3、Scope*1.1 This practice identifies and defines the duties, responsi-bilities, and minimum technical requirements of testing agencypersonnel and the minimum technical requirements for equip-ment utilized in testing concrete and concrete aggregates foruse in construction.1.2 This practice provides cri
4、teria for the evaluation of thecapability of a testing agency to perform designatedASTM testmethods on concrete and concrete aggregates. It can be used byan evaluation authority in the inspection or accreditation of atesting agency or by other parties to determine if the agency isqualified to conduc
5、t the specified tests.NOTE 1Specification E329 provides criteria for the evaluation ofagencies that perform the inspection of concrete during placement.1.3 This practice provides criteria for Inspection Bodies andAccreditation Bodies that provide services for evaluation oftesting agencies in accorda
6、nce with this practice.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior

17、dard:3.2.1 evaluation authority, nan independent entity, apartfrom the testing agency being evaluated, that has the capabilityto provide an unbiased evaluation of the professional andtechnical activities of concrete and concrete aggregates testingagencies.3.2.1.1 DiscussionTwo acceptable methods of
18、evaluationare inspection and accreditation, and these evaluations areoffered by many evaluation authorities. An inspection is anevaluation of 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
19、theprocess for an inspection agency. The testing agency beingevaluated performs corrective actions for any deficienciesnoted, and these corrections are to be placed with the otherinspection documentation as part of the permanent record ofthe inspection. An accreditation agency uses the results of th
20、einspection report or the results of their own onsite assessmentas one phase of the accreditation process. As a separate phase,the accreditation agency also reviews the testing agencyscorrective actions for the deficiencies noted and issues acertificate of accreditation once all of the deficiencies
21、havebeen corrected. There is no universally accepted evaluationauthority in the construction materials testing field; therefore,testing agencies should give careful consideration when select-ing an evaluation authority to gain the most benefit from theevaluation. In most cases, a testing agency will
22、 select anevaluation authority as a result of requirements in a projectspecification, or contract, or in response to local codes, or otherindustry requirements. In those circumstances, the require-ments will stipulate the acceptable evaluation authorities. Ifthere are no specific requirements and th
23、e evaluation is inanticipation of future work or to compete with other localtesting agencies, then the agency should contact the organiza-tion(s) most likely to use their services for a list of acceptableevaluation authorities. A list of evaluation authorities is pro-vided in the Qualification of Pe
24、rsonnel and Laboratory Evalu-ation section of the Manual of Aggregate and ConcreteTesting.5The list is merely a collection of organizations willingto provide this service and is not an endorsement of anyparticular organization. Other organizations may also be avail-able to provide this service.3.2.2
