Introduction
Metal products (such as steel bars, steel strands, anchors, etc.) are widely used in construction, bridges, highways, water transportation and other construction engineering fields.
The quantity directly affects the quality and safety of construction projects, and the technical capabilities of inspection agencies have also attracted more and more attention from industry authorities and the society. can
As a kind of conformity assessment activity, force verification has gradually become a technical force for testing institutions such as industry authorities, accreditation agencies, and users of test results.
An important means for evaluating technical ability.
GB/T 27043-2012 specifies the capabilities required by proficiency testing providers and the general requirements for establishing and operating proficiency testing plans.
Organization and management of proficiency testing in all inspection and testing fields. This standard is based on GB/T 27043, combined with metals used in construction projects
The characteristics and requirements of the field of product mechanical performance testing provide guidance for the development of proficiency testing activities, which will help standardize capabilities in this field
The organization and implementation of the verification plan.
This standard does not involve the content required for the management of proficiency testing providers. For related content, see GB/T 27043-2012.
