17、erms Specific to This Standard: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 Discussion
18、Two 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 of thequality system. An inspection re
19、port 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 ofthe inspection. An accreditation age
20、ncy 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 issues acertificate of accreditation onc
21、e 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 benefit from theevaluation. In most ca
22、ses, 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 evaluation authorities. Ifthere are no sp
23、ecific 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 of evaluation authorities is pro-vided
24、in the Qualification of Personnel 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
25、provide this service.3.2.2 external technical services, nthose services requiredby a testing agency that are provided by another organization.3.2.3 field technician, nan employee of the agency who isassigned to perform sampling and testing functions outside thelaboratory.3.2.4 laboratory technician,

This includes organi-zations that offer commercial testing services, an in-housequality control function, an academic institu
28、tion, or any otherorganization providing the required testing services, whetherperformed in the laboratory or in the field.4. Significance and Use4.1 The testing and inspection of concrete and concreteaggregates are important elements in obtaining quality con-struction. A testing agency providing th
29、ese 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.
