18、 Conformity AssessmentGeneral Requirements For Accreditation Bodies Accrediting Conformity AssessmentBodies53. 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
19、 independent entity, apart from the testing agency being evaluated, that has the capability toprovide an unbiased evaluation of the technical activities of concrete and concrete aggregates testing agencies in accordance withAnnex A1 or Annex A2.3.2.1.1 DiscussionTwo acceptable methods of evaluation
20、are inspection and accreditation, and these evaluations are offered by many evaluationauthorities. An inspection is an evaluation of equipment and procedures based on the Test Methods and Procedures section, alongwith a review of the quality system.An inspection report is the final step in the proce
21、ss for an inspection agency.The testing agencybeing evaluated performs corrective actions for any deficiencies noted, and these corrections are to be placed with the otherinspection documentation as part of the permanent record of the inspection. An accreditation agency uses the results of theinspec
22、tion report or the results of their own onsite assessment as one phase of the accreditation process. As a separate phase, theaccreditation agency also reviews the testing agencys corrective actions for the deficiencies noted and issues a certificate ofaccreditation once all of the deficiencies have
23、been corrected. There is no universally accepted evaluation authority in theconstruction 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 sel
24、ect an evaluation authority as a resultof requirements in a project specification, 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 theev
25、aluation is in anticipation of future work or to compete with other local testing 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 Personn
