(ISO/IEC 17025 Accreditation)

The Industrial Hygiene Laboratory Accreditation Program (IHLAP), has been accrediting labs for more than 40 years.

The Industrial Hygiene Laboratory Accreditation Program is designed specifically for laboratories involved in analyzing samples to evaluate workplace exposure. Participation assists the laboratory in maintaining high-quality standards.

Please review Policy Module 3​ for more information before applying for AIHA LAP Accreditation Programs.

Why Participate in the Industrial Hygiene Laboratory Accreditation Program?

When a laboratory is accredited by AIHA LAP, the laboratory and its clients have the assurance that the laboratory has met defined standards for performance based on examination of a variety of criteria. The AIHA IHLAP is the largest program of its kind in the world and has been in operation since 1974. When an IH laboratory is accredited by AIHA LAP, it becomes part of an elite group of laboratories achieving and maintaining a high level of professional performance.

Who Should Participate in the​ Program?

An industrial hygiene laboratory is a laboratory that analyzes samples taken in the workplace environment. Since the results of these analyses are used to determine the magnitude or presence of a problem in the workplace environment, it is vital that the laboratory analyzing the samples be proficient in producing high-quality data on which important health decisions will be based. Accreditation from AIHA LAP is a mark of that capability.

What if an Organization has Multiple Industrial Hygiene Laboratories?

If an organization has a number of in-house industrial hygiene laboratories based in different locations, each location will be identified as a separate entity, and each must individually comply with all accreditation requirements.
