Terminology3.1 Definitions:3.1.1 For definitions of terms used in this practice, refer to Terminology C125.3.2 Definitions of Terms Specific to This Standard:3.2.1 evaluation authority, nan independent entity, apart from the testing agency being ev
19、aluated, that has the capability toprovide an unbiased evaluation of the professional and technical activities of concrete and concrete aggregates testing agencies.3.2.1.1 DiscussionTwo acceptable methods of evaluation are inspection and accreditation, and these evaluations are offeredby many evalua
20、tion authorities. An inspection is an evaluation of equipment and procedures based on the Test Methods andProcedures section, along with a review of the quality system. An inspection report is the final step in the process for an inspectionagency. The testing agency being evaluated performs correcti
21、ve actions for any deficiencies noted, and these corrections are to beplaced with the other inspection documentation as part of the permanent record of the inspection. An accreditation agency usesthe results of the inspection report or the results of their own onsite assessment as one phase of the a
22、ccreditation process. As aseparate phase, the accreditation agency also reviews the testing agencys corrective actions for the deficiencies noted and issuesa certificate of accreditation once all of the deficiencies have been corrected. There is no universally accepted evaluation authorityin the con
23、struction materials testing field; therefore, testing agencies should give careful consideration when selecting an evaluationauthority to gain the most benefit from the evaluation. In most cases, a testing agency will select an evaluation authority as a resultof requirements in a project specificati
24、on, or contract, or in response to local codes, or other industry requirements. In thosecircumstances, the requirements will stipulate the acceptable evaluation authorities. If there are no specific requirements and theevaluation is in anticipation of future work or to compete with other local testi
25、ng agencies, then the agency should contact theorganization(s) most likely to use their services for a list of acceptable evaluation authorities. A list of evaluation authorities isprovided in the Qualification of Personnel and Laboratory Evaluation section of the Manual of Aggregate and Concrete Te
26、sting.5The list is merely a collection of organizations willing to provide this service and is not an endorsement of any particularorganization. Other organizations may also be available to provide this service.3.2.2 external technical services, nthose services required by a testing agency that are

This includes organizations that offer commercial testing services, an in-house qualitycontrol function, an academic institution, or any other organization providing the required testing services, whether performed inthe laboratory or
30、in the field.4. Significance and Use4.1 The testing and inspection of concrete and concrete aggregates are important elements in obtaining quality construction. Atesting agency providing these services must be selected with care.4.2 A testing agency shall be deemed qualified to perform and report th
31、e results of its tests if the agency meets the requirementsof this practice. The testing agency services shall be provided under the technical direction of a registered professional engineer.4.3 This practice establishes essential characteristics pertaining to the organization, personnel, facilities
32、, and quality systems ofthe testing agency. This practice may be supplemented by more specific criteria and requirements for particular projects.3Available from American Concrete Institute (ACI), P.O.
