Terminology3.1 Definitions:3.1.1 evaluation authority, nan independent entity, apa
17、rtfrom the testing laboratory being evaluated, that has thecapability to provide an unbiased evaluation of the professionaland technical activities of concrete and concrete aggregatestesting laboratories.3.1.1.1 DiscussionTwo acceptable methods of evaluationare inspection and accreditation, and thes
18、e 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 theprocess for an inspection agency. The testing lab
19、oratory 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 theinspection report or the results of their own o
20、nsite assessmentas one phase of the accreditation process. As a separate phase,the accreditation agency also reviews the testing laboratoryscorrective actions for the deficiencies noted and issues acertificate of accreditation once all of the deficiencies havebeen corrected. There is no universally
21、accepted evaluationauthority in the construction materials testing field; therefore,testing laboratories should give careful consideration whenselecting an evaluation authority to gain the most benefit fromthe evaluation. In most cases, a testing laboratory will select anevaluation authority as a re
22、sult 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 evaluation is inanticipation of futu
23、re work or to compete with other localtesting laboratories, then the laboratory should contact theorganization(s) most likely to use their services for a list ofacceptable evaluation authorities.3.1.2 external technical services, nthose services requiredby a testing laboratory that are provided by a

This mayinclude organizations that offer commercial testing services, anin-house quality control function, an academic institution, orany other organization providing the required testing services.3.1.7 Additional definitions c
