Inspection Body Accreditation Program

The A2LA Inspection Body Accreditation Program offers accreditation for the inspection and conformity of a wide variety of processes and products.

A2LA recognizes the very close relationship between inspection, sampling, laboratory testing and measurement, yet understands that inspection encompasses a variety of activities not covered in laboratory accreditation. Inspection activities include examinations by qualified personnel of materials, products, components, assemblies, cargoes, and consignments using techniques that include the following:

  • Visual examination  
  • Visual comparison with standards (e.g., color matching)  
  • Dimensional checks  
  • Examination using gauges and instruments
  • Virtual evaluations

An inspection body may also participate in testing, measurement, or sampling and may apply for accreditation in multiple fields concurrently.
