Second edition · September 2026 · regulatory cut-off 5 September 2026
"10 ppm" and "0.1% of the normal therapeutic dose" are not regulatory requirements.
A literal string search across eight official EU and EMA documents returns zero occurrences. 266 pages and 19 editable tools to derive limits from the HBEL, measure them with methods that can actually see them, and defend them in front of an inspector whose question is not "what is the limit" but "where does this number come from". This edition absorbs the SOP + Protocol bundle sold at €99, and the price stays €149.

Two editions, not two languages in one file. The guide and the toolkit exist in two editions only, Italian and English, of identical structure: choose the ITA - Italiano or the ENG - English variant. Purchase gives access to the edition you choose.
The guide
24 chapters in six parts that run from the clause to the decision, and from the decision to the evidence that holds it up. Every regulatory statement carries the clause, the date and the status of the text behind it, plus a label declaring its force: legal obligation, authority expectation, voluntary technical standard, or a decision the site has to justify.
The toolkit
19 editable tools per edition — 11 Excel workbooks with live formulas, unit checks and independent recalculation, and 8 Word documents with model text, revision history and approval tables. 38 files in total. No limit, frequency, swab area or number of repetitions is pre-loaded: they are placeholders to be set with your own site's rationale.
Lifetime updates
The framework is moving: PIC/S PI 006-3 applies until 30/09/2026 and PI 006-4 comes into force on 01/10/2026 without either 10 ppm or 0.1% of the normal therapeutic dose; the veterinary Regulation has applied since 16/07/2026; the concept paper on the revision of Annex 15 closed consultation in April 2026. When the texts change you receive the revised guide and toolkit at no further cost.
€149, unchanged — with a €99 product inside it
This edition fully absorbs the "Bundle Cleaning Validation GMP | SOP + Protocol", which GuideGxP sold separately at €99.00 and which is now archived as a standalone product. Its cleaning SOP and its cleaning validation protocol become Tools 12 and 13 of the toolkit: rewritten from scratch, made fully parametric and — for the first time — available in Italian as well as English.
The price of the guide does not change: €149.00. The first edition was 160 pages and no editable files; this one is 266 pages and 38 files.
The 19 tools in the toolkit
Eleven Excel and eight Word, in Italian and in English: 38 files. No operational value is pre-loaded. Limits, frequencies, recovery percentages, hold times, swab areas, numbers of sampling points, campaign lengths and visual thresholds are "to be defined" placeholders, and every worked example number is declared fictitious on the line where it appears. The number of validation repetitions is always a parametric field accompanied by a risk assessment rationale. Every checklist line carries its precise regulatory reference, and every tool states what it does not demonstrate. No tool reproduces or adapts tables, figures or templates from ISO, ASTM, PDA, ISPE, APIC or USP.
EXCEL
01 · HBEL/PDE Register and Toxicological Assessment Status
Per product: the HBEL expressed as a PDE or as a TTC with value and unit, who derived it and with what qualification, the date of the next reassessment. A second sheet lists the products without an HBEL, ranked by priority.
EXCEL
02 · MACO, MSC/MSSR and Operating Limits Calculator
The centre of the toolkit, and a calculator rather than a table: live formulas, unit checks with visible conversion, and a Verification sheet that recalculates independently. The historical methods are computed in a separate box, with their source, for comparison only.
EXCEL
03 · Product-Contact Surface and Process Train Inventory
Surface area per item of equipment and per part, with the unit and the estimation method declared. It includes the list of parts that get forgotten — hoses, IBCs, transfer lines, filters, hoppers, punches — with a mandatory tick.
EXCEL
04 · Grouping, Bracketing and Worst-Case Rating Matrix
Grouping families with the criterion for membership; criteria, weights and scale declared as a site choice; the toxicological, cleanability and solubility worst cases, which need not coincide; and a register of new products marked covered or not covered.
EXCEL
05 · Cleaning Process Risk Assessment (FMECA / HACCP)
An explicit risk question and an acceptability criterion declared in advance on a separate, dated sheet. The "observation" column exists because a risk assessment that assumes controls without having seen them is a deficiency the inspectorate has described in writing.
EXCEL
06 · Sampling Plan and Swab Point Register
Per point: the selection rationale in a mandatory column, the declared sampled area, the applicable limit with its unit, the qualified operator. A coverage sheet states which materials and methods have a recovery study behind them and which do not.
EXCEL
07 · Recovery Study: Data Collection and Factor Calculation
The factor per material × method × level combination, with mean, standard deviation and replicates; a matrix flagging uncovered combinations; and an Impact sheet that signals when the recovery-corrected limit falls below the LOQ.
EXCEL
08 · Analytical Method Selection and LOQ Requirements
The LOQ ↔ recovery-corrected limit comparison with a calculated outcome, method validation status, and a mandatory "what the method does not see" column for non-specific methods. Plus the positive control: uncleaned equipment must return an unacceptable result.
EXCEL
09 · Results Register, Trending and Cleaning Process Capability
Distance from the limit, margin of safety, trend charts per point and per item of equipment, identification of the limiting case, and a count of repeated alert limit excursions. No capability index and no threshold are pre-loaded: the statistic is the site's choice.
EXCEL
10 · Equipment Cleaning and Use Log
The record required by 21 CFR 211.182, and the first one an inspector asks for. It computes actual dirty and clean hold times and compares them with the validated intervals; a dedicated sheet handles dedicated equipment, where the records live in the batch record.
EXCEL
11 · Cleaning Validation Programme Dashboard
A product × equipment matrix showing coverage status, the date of the last change that could have invalidated the validation, the ongoing verification regime and the reason it is that one. One sheet is dedicated to the veterinary scope.
WORD
12 · Equipment Cleaning SOP (parametric template)
Replaces, in two languages, the SOP from the archived bundle. A step-by-step procedure in the imperative with every parameter as a placeholder and a "validated value" field beside it, maximum dirty and clean hold times, and a mandatory stop at visual inspection.
WORD
13 · Cleaning Validation Protocol
Replaces, in two languages, the protocol from the archived bundle, and it is the document the programme is judged on. Fifteen sections, with the consistency table "worst case condition declared | how it is realised in the run | evidence" and the number of repetitions as a parametric field.
WORD
14 · Cleaning Validation Report
Results per point in the same unit as the protocol, with a unit reconciliation table; deviations with the rationale for accepting or invalidating the run; and an explicit conclusion, because an ambiguous conclusion is not a conclusion.
WORD
15 · Acceptance Limit Rationale
The document that answers "where does this limit come from": the derivation chain step by step with units, the comparison against the historical limit and its outcome, and the margin below the HBEL justified in terms of cleaning process capability.
WORD
16 · Visual Threshold Study and Inspector Qualification Protocol
Declared observation conditions — lighting, distance, angle — a safety factor between laboratory and shop floor with its rationale, and the inspector qualification section: training, vision testing, practical competence, requalification.
WORD
17 · Hold Time and Campaign Study Protocol
Three distinct studies in a single protocol: dirty hold time, clean hold time with microbiological as well as chemical analytes, and campaign length, with the constraint that the validation run is performed at the end of the maximum campaign. No interval is pre-loaded.
WORD
18 · Change Impact Assessment on Cleaning Validation
Eleven change categories; the golden rule — cleaning becomes lighter or heavier, and with what consequences; the decision between no revalidation, limited verification and revalidation; and the blocking condition that keeps the change open until the validation work is complete.
WORD
19 · Inspection Simulation Kit
"Question | expected evidence | red flag" tables across ten macro-areas; a traceability exercise that starts from a number picked at random out of the report and works back to its source; a dossier red flag checklist; and a scored self-assessment with no pass mark pre-loaded.
You use it from tomorrow morning
| The situation |
What you use |
| I have to justify a limit the site has used for ten years |
Chapters 2 and 8 + Tools 02 and 15: the documented comparison between the historical limit and the HBEL-derived limit, and the relocation of the historical limit as an alert limit on the conditions set out in EMA Q&A Q6 |
| I do not know whether my product has an HBEL, or who derived it |
Chapter 5 + Tool 01: a register carrying the qualification of the person who derived it, the documented assessment of the external provider, and the priority-ranked sheet of products with no HBEL |
| I have to calculate the MACO and I do not want the batch size wrong |
Chapters 6 and 7 + Tool 02: the batch size is that of the next product, with unit checks, scale plausibility checks and a Verification sheet that recalculates independently |
| The method's LOQ does not reach the calculated limit |
Chapter 16 + Tool 08: the answer is not to raise the limit. The routes are to change method or to apply Chapter 3 §3.6 (iii), and the sheet computes the outcome of the comparison |
| I have to decide how many times to repeat the validation |
Chapter 18 + Tools 13 and 18: the number is a parametric field accompanied by a risk assessment rationale. Annex 15 §10.13 asks for "an appropriate number of times based on a risk assessment" |
| A change touches the detergent, the scale or the equipment |
Chapter 21 + Tool 18: eleven categories, impact on HBEL, MACO, surfaces, worst case and hold times, and the blocking condition that keeps the change open until the validation work is complete |
| I also manufacture for veterinary use |
Chapter 3 + Tool 11, veterinary scope sheet: since 16/07/2026 Regulation (EU) 2025/2091 obliges, with "shall", and provides the only binding definition of cleaning validation in this scope |
| I have an inspection in two weeks |
Chapter 24 + Tool 19: 47 questions with expected evidence, 18 dossier red flags, and the traceability exercise that starts from a number in the report and works back to the chromatogram |
Where "10 ppm" and "0.1% of the normal therapeutic dose" actually come from
Eight official documents, zero occurrences. A literal string search on the official PDFs of Annex 15 §10 (clauses 10.1–10.15), EudraLex Part I Chapter 3 §3.6, Chapter 5 §5.17–5.22, Part II §12.70–12.76, the EMA HBEL guideline (EMA/CHMP/CVMP/SWP/169430/2012), its Q&A (EMA/CHMP/CVMP/SWP/246844/2018), Regulation (EU) 2025/2091 Annex V, and PIC/S PE 009-17 Annex 15. Neither criterion appears in any of the eight. What each text asks for instead is a toxicological evaluation. Anyone can repeat this check in an afternoon with the public PDFs and a search box: it is that reproducibility that makes the statement defensible in an audit rather than merely polemical.
They survive in two live texts only. PIC/S PI 006-3 §7.11.3 introduces them with "for example" inside a recommendation, and it is applicable until 30/09/2026. WHO TRS 1019, Appendix 3 §11.9 calls them "the three most commonly used criteria" — an observation of common practice, not a prescription — in a 2006 text that does not contain the word HBEL, and in a parenthesis it reveals where the 10 ppm came from: "basis for heavy metals in starting materials", a limit born for heavy metals in starting materials and carried across to residues by analogy.
The 1993 FDA inspection guide does not recommend them. It is reference material written for investigators and it binds neither FDA nor industry. It states that FDA does not intend to set acceptance specifications and then, immediately afterwards, reports those values as limits "mentioned by industry representatives in the literature or in presentations". They are not FDA limits and they are not FDA recommendations: they are what industry was saying in 1993, recorded by a document whose content has stood still since 1993.
What stands in their place, and what changes on 01/10/2026. EMA Q&A 246844/2018, Q6, never names the figures: it sets the HBEL as the ceiling, relocates historical limits as conditional alert limits, and asks that repeated excursions not be accepted. And PIC/S PI 006-4, published on 30/07/2026 and in force from 01/10/2026, replaces §7.11 with a §7.12 that carries neither 10 ppm nor 0.1% of the normal therapeutic dose; until 30/09/2026 PI 006-3, which does carry them, remains applicable. A cleaning guide published across that date that failed to state both effective dates would be wrong for half the year.
What this means for your dossier — and the only "obliges" on this page. It does not mean those criteria are forbidden: the 2018 Q&A retains them, conditionally. It means they are not requirements, and that presenting them as requirements weakens the dossier in front of an inspector who asks where the number comes from. The only text that obliges, in this scope, is Commission Implementing Regulation (EU) 2025/2091 — veterinary, directly applicable since 16/07/2026 — which with "shall" brings cleaning validation inside a text of law and provides the only binding definition. Annex 15, EudraLex, PIC/S, ICH, WHO, ISO, PDA, ISPE, APIC and ASTM never carry a mandatory verb in this volume, and the labels say so line by line. Regulatory cut-off 5 September 2026, with a register of 63 sources carrying designation, edition, date and status. The 15 findings in Chapter 22 are read from published official documents — 6 FDA Warning Letters from 2024-2026 and 9 EudraGMDP Statements of Non-Compliance — and are anonymised without exception: never a company name, never a brand, never a product name.
Inside the guide
Part I — What the sources actually say (chs. 1-4). How to use the guide; the textual verification across the eight documents, and every text in scope that says anything about limits, set side by side; the two legal chains — guidance for human use, law for veterinary use; the map of Annex 15 §10, Chapters 3 and 5, Part II and 21 CFR.
Part II — The limit: HBEL, PDE, MACO (chs. 5-8). HBEL, PDE, ADE and TTC: four acronyms, three meanings and one divergence recorded and left unresolved; from the HBEL to a quantity of residue; from the MACO to the limit the laboratory actually measures; alert limits, cleaning process capability and margin of safety.
Part III — Designing the programme (chs. 9-12). The cleaning lifecycle and the architecture of the programme; developing the cleaning process — manual, COP, CIP; grouping, bracketing and worst case selection; the risk assessment of the cleaning process, with controls observed rather than assumed.
Part IV — Measuring (chs. 13-17). Swab, rinse and what neither technique sees; visual inspection as a method that is qualified; recovery, where the obligation exists and the threshold does not; specific, non-specific and the question of TOC; bioburden and endotoxins on product-contact surfaces.
Part V — Executing, maintaining, changing (chs. 18-21). The protocol and its execution, with worst case conditions declared and actually realised; results, deviations and the report; hold times, campaigns and dedicated equipment; change control, revalidation and ongoing verification.
Part VI — Proving it in an inspection (chs. 22-24). The 15 verified inspection findings and the themes that recur; the full applied scenarios; inspection readiness with 47 questions in question / expected evidence / red flag format, 18 dossier red flags, and the construction of the cleaning validation file.
Plus 5 appendices. A register of the 63 cited sources with designation, edition, date, status and the chapters that cite them; a regulatory status matrix; the 145 decisions the book asks you to take, each mapped to chapter, decision owner, document and tool; 19 tool sheets; and a glossary of 86 entries, which opens with the only two binding definitions in scope.

Who it is for. QA Managers and Heads of Quality, Qualified Persons, Validation and CQV, QC and the analytical laboratory, Manufacturing, Microbiology, Regulatory Affairs, Engineering, consultants and auditors, veterinary and mixed sites, CDMOs. It is written for people who already have the regulations: it does not explain what cross-contamination is and it does not summarise GMP. It explains which decision to take, on what basis, who signs it, in which document it is recorded, and how it is defended in an inspection.
Who it is not for. Anyone looking for a number to copy into a protocol will not find one: no limit, no frequency, no swab area and no number of repetitions is pre-loaded, because no source in scope sets one generally. Also out of scope, each with its own volume in the series: contamination control strategy, environmental monitoring, cleaning and disinfection of classified areas, pharmaceutical water, aseptic fill-finish, cleanroom classification, and the Validation Master Plan. We would rather say so here than let you find out halfway through the volume.
Do you need to justify a limit, rebuild a protocol or defend your site's programme?
Describe the site, the scope (human, veterinary or mixed) and the point where you are stuck. GuideGxP will assess the request and, where appropriate, may put you in touch with a specialist compatible with your technical needs and your geography.

No purchase required. Requests are assessed before any referral to a specialist.
GuideGxP guides do not replace official regulation (EMA, EU GMP, ICH, PIC/S, ISO, EN, FDA, pharmacopoeias): they are operational support tools, and the user remains responsible for the correct application of the regulations in force in their own corporate context. ISO, ASTM, PDA, ISPE, APIC and USP documents are voluntary and paid: their full text must be purchased from the body that publishes them and is not reproduced here. Warning Letters express FDA's position on alleged violations and are not judicial determinations. Digital product: no physical shipment.
