NVLAP is a voluntary system for assessing and evaluating testing laboratories and accrediting those found competent to perform specific test methods or types of test methods. Laboratory accreditation programs are established for specified product or service areas in response to requests and demonstrated need. The publication, intended for the NVLAP technical experts who serve as assessors and evaluators, describes general policies and practices of NVLAP assessment and evaluation. The specific technical criteria for assessing and evaluating laboratories are provided elsewhere, in NVLAP Handbooks and checklists for each technical area. 收起
