Full title and description

Cleanrooms and associated controlled environments — Biocontamination control — Part 2: Evaluation and interpretation of biocontamination data (ISO 14698-2:2003). This part gives guidance on methods for the evaluation of microbiological monitoring data and estimation of results obtained from sampling of viable particles in risk zones; it is intended to be used, where appropriate, together with ISO 14698-1.

Abstract

ISO 14698-2:2003 provides guidance on statistical and practical methods to evaluate microbiological monitoring data from cleanrooms and associated controlled environments, including approaches to estimate concentrations from discrete samples, interpret results against control criteria, and report findings. A technical corrigendum to the 2003 edition was published in 2004.

General information

• Status: Published (Edition 1, 2003). ISO record indicates the standard has been subject to review/withdrawal ballot activity.
• Publication date: 2003 (ISO edition published September 2003 / catalog entries commonly list October 2003).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 13.040.35 (Cleanrooms and associated controlled environments; biocontamination control).
• Edition / version: Edition 1 (2003). Technical corrigendum: ISO 14698-2:2003/Cor 1:2004.
• Number of pages: 11 (main ISO PDF listing).

Scope

ISO 14698-2:2003 covers guidance for the evaluation and interpretation of viable microbiological monitoring data obtained from cleanrooms and associated controlled environments used in industries such as pharmaceutical, biotechnology, medical devices and healthcare. It addresses statistical treatment of sampling results, estimation of airborne and surface viable particle concentrations from discrete samples, comparison with control or alert levels, and reporting formats; it does not itself set specific regulatory limits but supports consistent interpretation and decision-making.

Key topics and requirements

• Statistical methods for evaluating microbiological monitoring results (treatment of low-count data, estimation techniques).
• Guidance on interpreting discrete sample results against control/alert criteria and risk zones.
• Methods to estimate viable particle concentrations from sampling data and to express uncertainty.
• Recommendations for reporting formats and documentation of microbiological monitoring programs.
• Use in conjunction with ISO 14698-1 (general principles and methods for biocontamination control) and applicable cleanroom standards.
• Corrections and clarifications published as a technical corrigendum in 2004.

Typical use and users

Primary users are contamination-control specialists, validation and quality assurance engineers, microbiologists, production managers and regulatory/compliance personnel in pharmaceutical, biotechnology, sterile medical device manufacturing, hospital sterile services, and laboratories. The standard is used when analysing and interpreting microbiological monitoring data to support process control, environmental monitoring programs, investigations, and regulatory submissions.

Related standards

Key related documents include ISO 14698-1:2003 (Part 1 — general principles and methods), the ISO 14644 series on cleanroom classification and testing (for airborne particle control), and regional/adopted standards and successors such as EN 17141:2020 which has been used in some jurisdictions to update or replace earlier regional adoptions of ISO 14698 material. The technical corrigendum ISO 14698-2:2003/Cor 1:2004 also applies.

FAQ

Q: What is this standard?

A: ISO 14698-2:2003 is the second part of the ISO standard series on biocontamination control for cleanrooms; it provides guidance on the evaluation and interpretation of microbiological monitoring data collected in controlled environments.

Q: What does it cover?

A: It covers statistical and practical approaches to analyse viable-particle sampling results, estimate concentrations from discrete samples, interpret results relative to control or alert criteria, and present monitoring findings — intended to be applied alongside ISO 14698-1 (general principles).

Q: Who typically uses it?

A: Contamination-control specialists, microbiologists, validation/QC engineers, production and facility managers in pharmaceutical, biotech, medical device, hospital sterile services, and laboratory environments — anyone responsible for environmental monitoring program design, data review, investigations, or regulatory compliance.

Q: Is it current or superseded?

A: The edition was published in 2003 with a technical corrigendum in 2004. ISO’s catalog shows the document as published but indicates review/withdrawal activity (withdrawal ballot initiated status at ISO catalog), and several regional adoptions based on this standard have been withdrawn or superseded (for example, some European adoptions were replaced by EN 17141:2020). Users should verify the current status in their country and check for newer ISO or regional standards before relying on it for compliance decisions.

Q: Is it part of a series?

A: Yes — ISO 14698 is a two-part series: Part 1 (ISO 14698-1:2003) covers general principles and methods for biocontamination control; Part 2 (this document) covers evaluation and interpretation of the data. The ISO 14644 series on cleanrooms is also closely related.

Q: What are the key keywords?

A: Biocontamination, viable particles, microbiological monitoring, cleanrooms, controlled environments, sampling interpretation, environmental monitoring, ISO 14698-2.
