18、Annex A1 or Annex A2.3.2.1.1 DiscussionTwo acceptable methods of 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
19、 of thequality system. An inspection report is the final step in 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
20、 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 accreditation agency also reviews the testing agencyscorrective actions for the deficiencies noted and i
21、ssues acertificate of accreditation once all of the deficiencies 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
22、 benefit from theevaluation. In most cases, a testing agency will 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 ev
23、aluation authorities. Ifthere are no specific requirements and the 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
24、of evaluation authorities is pro-vided in the Qualification of Personnel and Laboratory Evalu-ation section of the Manual of Aggregate and ConcreteTesting.6The list is merely a collection of organizations willingto provide this service and is not an endorsement of anyparticular organization. Other o

Significance and Use4.1 The testing and inspection of concrete and concreteaggregates are important elements in obtaining quality con-str
29、uction. A testing agency providing these services must beselected with care.4.2 A testing agency shall be deemed qualified to performand report the results of its tests if the agency meets therequirements of this practice. The testing agency services shallbe provided under the technical direction of
30、 a registeredprofessional engineer.4.3 This practice establishes essential characteristics per-taining to the organization, personnel, facilities, and qualitysystems of the testing agency. This practice may be supple-mented by more specific criteria and requirements for particu-lar projects.5. Organ
