4、ice provides criteria for the evaluation of thecapability of a testing laboratory to perform designated ASTMtest methods on concrete and concrete aggregates. It can beused by an evaluation authority in the inspection or accredita-tion of a laboratory or by other parties to determine if thelaboratory

6、testing laboratories in accordance with this practice.1.4 If the laboratory requires external technical services toconduct tests, the external agency shall be subject to separateevaluation.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is
7、 theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

17、Terminology3.1 Definitions:3.1.1 For definitions of terms used in this practice, refer toTerminology C125.3.2 Definitions of Terms Specific to This Standard:3.2.1 evaluation authority, nan independent entity, apartfrom the testing laboratory being evaluated, that has thecapability to provide an unbi
18、ased evaluation of the professionaland technical activities of concrete and concrete aggregatestesting laboratories.3.2.1.1 DiscussionTwo acceptable methods of evaluationare inspection and accreditation, and these evaluations areoffered by many evaluation authorities. An inspection is anevaluation o
19、f equipment and procedures based on the TestMethods and Procedures section, along with a review of thequality system. An inspection report is the final step in theprocess for an inspection agency. The testing laboratory beingevaluated performs corrective actions for any deficienciesnoted, and these
20、corrections are to be placed with the otherinspection documentation as part of the permanent record ofthe inspection. An accreditation agency uses the results of theinspection report or the results of their own onsite assessmentas one phase of the accreditation process. As a separate phase,the accre
21、ditation agency also reviews the testing laboratoryscorrective actions for the deficiencies noted and issues acertificate of accreditation once all of the deficiencies havebeen corrected. There is no universally accepted evaluationauthority in the construction materials testing field; therefore,test
22、ing laboratories should give careful consideration whenselecting an evaluation authority to gain the most benefit fromthe evaluation. In most cases, a testing laboratory will select anevaluation authority as a result of requirements in a projectspecification, or contract, or in response to local cod
23、es, or otherindustry requirements. In those circumstances, the require-ments will stipulate the acceptable evaluation authorities. Ifthere are no specific requirements and the evaluation is inanticipation of future work or to compete with other localtesting laboratories, then the laboratory should c
24、ontact theorganization(s) most likely to use their services for a list ofacceptable evaluation authorities. A list of evaluation authori-ties is provided in the Qualification of Personnel and Labora-tory Evaluation section of the Manual of Aggregate andConcrete Testing.5The list is merely a collecti
25、on of organiza-tions willing to provide this service and is not an endorsementof any particular organization. Other organizations may also beavailable to provide this service.3.2.2 external technical services, nthose services requiredby a testing laboratory that are provided by another organiza-tion
