The assessment of conformity assessment bodies (CABs) in the field of environmental testing is conducted as per ISO/IEC 17,025:2017 by the accreditation bodies (AB). All the environmental testing CABs are required to face the assessment for getting accreditation as per the applied scope of accreditation for the testing of air, water and soils samples. The CABs may undertake the testing of various samples as per the facility available within the CAB. The testing of environmental parameters can be segregated into three discipline, namely biological testing, chemical testing and mechanical testing. The techniques of assessment for the applicant CABs and accredited CABs can be divided into two categories, off site assessment and onsite assessment. The types of assessment adopted by the accreditation bodies (AB) can be different at different stage based on the requirement of the economic environment of the country. In this paper, the various types of assessment techniques along with the national accreditation processes in India are discussed.

认可机构 (AB) 根据 ISO/IEC 17,025:2017 对环境测试领域的合格评定机构 (CAB) 进行评估。要求所有环境检测认证机构按照空气、水、土壤样品检测认可的适用范围接受认可评估。CAB 可以根据 CAB 内可用的设施对各种样品进行测试。环境参数的测试可以分为三个学科，即生物测试、化学测试和机械测试。申请 CAB 和认可 CAB 的评估技术可分为非现场评估和现场评估两类。认可机构（AB）所采用的评估类型在不同阶段可以根据国家经济环境的要求而有所不同。本文讨论了各种类型的评估技术以及印度的国家认证过程。
