Overview
ISO 6141:2015/Amd 1:2020 is an important amendment to the international standard ISO 6141:2015, which specifies the contents of certificates for calibration gas mixtures used in gas analysis. This amendment introduces a comprehensive cross-reference list aligning the requirements of ISO 6141 with those of ISO Guide 31:2015 and ISO/IEC 17025:2017. These references enhance clarity and consistency in documenting information for calibration gas mixtures, facilitating improved conformity and traceability in laboratory practices.
Key Topics
This amendment focuses on harmonizing the certificate content requirements through:
-
Cross-reference Table: A detailed table (Table A.1) mapping elements from ISO 6141 to corresponding clauses in ISO Guide 31:2015 (contents of certificates for reference materials) and ISO/IEC 17025:2017 (general requirements for testing and calibration laboratories). This includes:
- Unique identification of reference material and certificate numbers
- Names and addresses of certifying bodies
- Description, intended use, and certified values of calibration gas mixtures
- Uncertainty and metrological traceability of certified values
- Dates (certification, preparation, analysis) and validity periods
- Methods of preparation and analysis
- Signatures of certifying officers
- Customer identification and number of document pages
-
Alignment to Laboratory Competence: Ensuring that certificates for calibration gases meet requirements for laboratory competence and quality control as stipulated by ISO/IEC 17025.
-
Reference to ISO 17034:2016: The note highlights that ISO 17034 sets similar requirements for reference material certificates, emphasizing uniformity for producers of calibration gases and related reference materials.
Applications
ISO 6141:2015/Amd 1:2020 is highly relevant to:
- Calibration Gas Producers: Assists producers in creating compliant certificates, ensuring traceability and reliability of calibration gas mixtures for industrial and environmental gas analysis.
- Testing and Calibration Laboratories: Supports laboratory accreditation processes by aligning certification documentation with internationally recognized competence requirements (ISO/IEC 17025).
- Quality Assurance Teams: Facilitates implementation of consistent documentation practices for calibration gases, improving audit readiness and regulatory compliance.
- Gas Analysis Equipment Manufacturers: Provides clear standards for traceable calibration gas certificates, crucial for validating sensor and analyzer accuracy.
- Regulatory Bodies and Certification Authorities: Offers a standardized framework to evaluate calibration gas documentation for conformity assessment.
Related Standards
For a comprehensive understanding and effective application, this amendment should be used alongside the following key standards:
- ISO Guide 31:2015 - Reference materials: Contents of certificates, labels, and accompanying documentation. This guide details best practices for documenting reference materials which underpin calibration procedures.
- ISO/IEC 17025:2017 - General requirements for the competence of testing and calibration laboratories. This standard specifies quality and technical requirements that laboratories must meet.
- ISO 17034:2016 - General requirements for the competence of reference material producers, ensuring that reference materials (including calibration gases) meet stringent quality standards.
By integrating the requirements of these standards, ISO 6141:2015/Amd 1:2020 provides a robust framework ensuring accuracy, traceability, and clarity in calibration gas certification, essential for effective and reliable gas analysis across various industries.
