The ANSI-ASQ National Accreditation Board/ACLASS provides accreditation to ISO/IEC 17025 for testing and calibration laboratories. ACLASS also provides accreditation for reference material producers (RMPs) to ISO Guide 34 and inspection bodies to ISO/IEC 17020. 

ACLASS is internationally recognized by ILAC, APLAC, and IAAC as a signatory of multilateral recognition arrangements (MRAs) that facilitate acceptance of test and calibration data between ACLASS-accredited laboratories and the international community.

Our strategy is to treat customers as partners while maintaining the integrity of the standards. ACLASS helps our customers and their customers realize the value and importance of accreditation. We help our customers enhance their business and technical performance by citing opportunities for improvement during our assessments. ACLASS assessors practice and maintain a congenial approach while conducting assessments. Our assessors undergo a rigorous selection process, with a focus on technical background and ability. In addition, we require that each assessor have effective communication skills and embrace our unique approach to customer service. Our competent assessors, strong customer service, and industry experience make ACLASS the best choice for accreditation.

ACLASS and its customers work together to build technical competence and quality assurance in the industry. Whether in staff training, documentation, analytical results, or customer satisfaction, our customers gain knowledge as a result of each visit by ACLASS. Our customers expand their thinking about accreditation and continually use it as a training tool and confidence builder for their quality and technical management systems.
