ASTM International has announced the addition of accreditation from the globally-recognized American Association for Laboratory Accreditation (A2LA) for nine of its proficiency testing programs. 

The new accreditations cover programs including:

• Cetane,
• Crude oil,
• Engine coolants,
• In-service diesel oil,
• Insulated fluid quality,
• Polypropylene,
• Thermal analysis of plastics, and more.

The recent additions bring the total number of ASTM International programs that have achieved A2LA accreditation to 28, including automotive lubricant additives, biodiesel, and many more. Nearly 60% of  ASTM’s proficiency testing programs have now been accredited. 

Programs accredited through A2LA are assessed against criteria from a key standard: Conformity Assessment – General Requirements for Proficiency Testing (ISO/IEC 17043:2010). 

More than 5,000 laboratories use ASTM’s statistical quality assurance tools in the proficiency testing programs. For more information, visit www.astm.org/ptp.
