Scope*1.1 This practice identifies and defines the duties,responsibilities, and minimum technical requirements of test-ing agency personnel and the minimum technical requirementsfor equipment utilized in testing concrete and concrete aggre-gates for use in construction.1.2 This practice provides
4、 criteria 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 co

17、an independent entity, apartfrom the testing agency being evaluated, that has the capabilityto provide an unbiased evaluation of the technical activities ofconcrete and concrete aggregates testing agencies in accor-dance with Annex A1 or Annex A2.3.2.1.1 DiscussionTwo acceptable methods of evaluatio
18、nare 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 theproces
19、s 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 theinspecti
20、on 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 havebeen
21、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 select a
22、nevaluation 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 the evaluat
23、ion 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 Personnel a
