1、Designation: C1077 10aStandard Practice forLaboratories Testing Concrete and Concrete Aggregates forUse in Construction and Criteria for Laboratory Evaluation1This standard is issued under the fixed designation C1077; the number immediately following the designation indicates the year oforiginal ado
2、ption 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.1.
3、 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 pract
4、ice 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 thelaboratory
5、 is qualified to conduct the specified tests.NOTE 1Specification E329 provides criteria for the evaluation oflaboratories that perform the inspection of concrete during placement.1.3 This practice provides criteria for Inspection Bodies andAccreditation Bodies that provide services for evaluation of
6、testing laboratories in accordance with this practice.1.4 If the laboratory requires external technical services toconduct tests, the external agency shall be subject to separateevaluation.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is
7、 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 use.2.

18、evaluation 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 equ
19、ipment 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 corre
20、ctions 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 accreditat
21、ion 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 l
22、aboratories 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, o
23、r 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 contac

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.5The list is merely a collection of
