1、Designation: C 1077 09aStandard Practice forLaboratories Testing Concrete and Concrete Aggregates forUse in Construction and Criteria for Laboratory Evaluation1This standard is issued under the fixed designation C 1077; the number immediately following the designation indicates the year oforiginal a
2、doption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.
3、1. Scope*1.1 This practice identifies and defines the duties, responsi-bilities, and minimum technical requirements of testing labo-ratory personnel and the minimum technical requirements forlaboratory equipment utilized in testing concrete and concreteaggregates for use in construction.1.2 This pra
4、ctice provides criteria for the evaluation of thecapability of a testing laboratory to perform designated ASTMtest methods on concrete and concrete aggregates. It can beused by an evaluation authority in the inspection or accredita-tion of a laboratory or by other parties to determine if thelaborato
5、ry is qualified to conduct the specified tests.NOTE 1Specification E 329 provides criteria for the evaluation oflaboratories that perform the inspection of concrete during placement.1.3 If the laboratory requires external technical services toconduct tests, the external agency shall be subject to se
6、parateevaluation.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to us

17、aluation of the professionaland technical activities of concrete and concrete aggregatestesting laboratories.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 equip
18、ment 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 laboratory beingevaluated performs corrective actions for any deficienciesnoted, and these correct
19、ions 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 onsite assessmentas one phase of the accreditation process. As a separate phase,the accreditatio
20、n 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 accepted evaluationauthority in the construction materials testing field; therefore,testing lab
21、oratories 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 result of requirements in a projectspecification, or contract, or in response to local codes, or
22、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 future work or to compete with other localtesting laboratories, then the laboratory should contact
23、theorganization(s) most likely to use their services for a list ofacceptable evaluation authorities. A list of evaluation authori-ties is provided in the Qualification of Personnel and Labora-tory Evaluation section of the Manual of Aggregate andConcrete Testing.4The list is merely a collection of o
24、rganiza-tions willing to provide this service and is not an endorsementof any particular organization. Other organizations may also beavailable to provide this service.3.2.2 external technical services, nthose services requiredby a testing laboratory that are provided by another organiza-tion.3.2.3
