标准简介
ISO/IEC 17025:2017 是检测和校准实验室能力的通用要求国际标准,是全球实验室认可体系的核心标准。该标准由国际标准化组织(ISO)和国际电工委员会(IEC)联合发布,为实验室展示其运营能力、产生有效结果的能力提供了要求框架。ISO 17025 认可是国际上互认实验室检测和校准数据的基础,通过国际实验室认可合作组织(ILAC)的互认协议(MRA)在全球范围内实现检测结果互认。
ISO/IEC 17025:2017 版引入了基于风险的思维方法,与 ISO 9001:2015 的管理体系要求更加协调。标准的主要要求包括两大部分:技术要求(人员能力、设施和环境条件、设备和溯源性、外部供应的产品和服务、方法选择和验证、抽样、测试和校准物品的处理、技术记录、测量不确定度评估、结果有效性保证、结果报告)和管理体系要求(文件管理、记录控制、纠正措施、内部审核、管理评审)。实验室可选择实施完整的 ISO 9001 管理体系(选项 A)或按标准附录要求实施管理体系(选项 B)。认可由各国认可机构(如中国 CNAS、美国 ANAB/A2LA、英国 UKAS)执行。
Laboratory Competence
Demonstrates that laboratories are technically competent and produce valid, reliable results. The globally accepted benchmark for testing and calibration laboratory quality.
Measurement Traceability
Requires that measurement results are traceable to the International System of Units (SI) through an unbroken chain of calibrations with stated measurement uncertainties.
Impartiality & Independence
Mandates that laboratories operate impartially, managing risks to impartiality and ensuring that commercial, financial, or other pressures do not compromise technical judgment.
list_alt Key Requirements
- Impartiality and confidentiality obligations
- Structural and resource requirements
- Personnel competence, training, and authorization
- Equipment calibration and metrological traceability
- Method selection, validation, and verification
- Sampling, handling, and transportation of test items
- Quality assurance of results and proficiency testing
- Management system requirements (Options A and B)
Who Needs to Comply?
Testing and calibration laboratories of any size in any sector — including environmental, forensic, clinical, food safety, materials testing, and calibration facilities. Required by many regulatory authorities and often mandated by industry standards and customer specifications.
Key Requirements
Impartiality
Laboratory activities must be undertaken impartially. The laboratory must identify risks to impartiality on an ongoing basis, including relationships with parent organizations, and demonstrate how such risks are eliminated or minimized.
Method Validation
Use appropriate methods and procedures for all tests and calibrations. Non-standard methods, laboratory-developed methods, and modified standard methods must be validated to confirm fitness for intended use.
Metrological Traceability
Ensure measurement results are traceable to SI units through documented unbroken chains of calibration. Maintain calibration records and evaluate measurement uncertainty for all quantitative results.
Quality Assurance of Results
Implement procedures to monitor the validity of results through proficiency testing, interlaboratory comparisons, use of certified reference materials, and replicate testing using the same or different methods.
Management System
Implement a management system covering document control, internal audits, management reviews, corrective actions, and handling of complaints. Two options: develop a bespoke system (Option A) or use an existing ISO 9001 system (Option B).
Penalties & Enforcement
No direct legal penalties — ISO 17025 is a voluntary accreditation standard. However, laboratories that lose accreditation may be unable to perform regulatory testing, lose contracts, and see their test results unrecognized by regulators and trading partners.
