In 1970, NIST, which was then called NBS, held a conference to consider a proposal for a voluntary national testing laboratory accreditation program. The program, in addition to providing laboratory examination services, would issue accreditations to provide national recognition to those laboratories found to be competent performing certain tests. Sections of Guide 25 on Accommodations and Environment , Equipment and Reference Materials , and Outside Support Services and Supplies , require a laboratory to provide itself with equipment and environments that do not adversely affect the tests and calibrations performed. Copies of the newly published handbook have been sent to applicant laboratories and assessors. Advance Data Tech.
