18、nology3.1 DefinitionsThe approved standard definitions arelisted below.3.1.1 quality system, nthe organizational structure,responsibilities, procedures, activities, capabilities, and re-sources that together aim to ensure that laboratory servicessatisfy data requirements.3.2 Definitions of Terms Spe
19、cific to This Standard:3.2.1 agency, nthe organization engaged to test or inspectroad and paving materials as required by a specification orcontract.3.2.2 quality system manual (QSM)a set of documentsdescribing an agencys quality system.3.2.3 userthe person or organization engaging the agencyto prov
20、ide inspections or tests; or using this specification toevaluate or accredit the agency.3.2.4 calibration, na process that establishes the relation-ship (traceability) between the results of a measurementinstrument, measurement system, or material measure and thecorresponding values assigned to a re
21、ference standard.3.2.4.1 DiscussionThe purpose of calibration is to estab-lish the traceability of a measurement on certain types ofequipment, such as balances (measurement instrument) anddynamic shear rheometer (measurement system). Uncertaintyestimates obtained during calibration are used to judge
22、 if aninstrument is suitable for its intended purpose. There is a needto re-establish traceability or recalibrate only when instrumentmeasurements drift out of control (as determined throughverification of calibration).3.2.5 check, na specific type of inspection and/or mea-surement performed on equi
23、pment and materials to indicatecompliance or otherwise with stated criteria.3.2.5.1 DiscussionChecks are performed on items ofequipment that do not make measurements, such as specimenmolds and ovens. Stated criteria can be dimensional tolerances.3.2.6 quality system manual (QSM), na set of documents
24、describing an agencys quality system.3.2.7 standardization, na process that determines whetheradjustments are needed to a specific piece of equipment, suchas pycnometers and flow meters, when its performance iscompared with that of a generally accepted standard.3.2.8 traceability, nthe property of a
25、 result of a measure-ment whereby it can be related to stated references, usuallynational or international standards, through an unbroken chainof comparisons all having stated uncertainties.3.2.8.1 DiscussionThere is a need for traceable measure-ments. Measurements, not the instrument, can be tracea
26、ble.Measurement traceability is established through calibration.Measurement traceability is maintained through check ofcalibration (a regular check of instrument output using acontrol standard).3.2.9 uncertainty, na parameter associated with the resultof a measurement that defines the range of the v
27、alues that couldbe attributed to the measured quantity.3.2.9.1 DiscussionThe uncertainty of a measurement isrequired in order to establish its traceability. The uncertaintyestimates obtained during calibration are used to judge if aninstrument is suitable for its intended purpose.3.2.10 user, nthe p
28、erson or organization engaging theagency to provide inspections or tests; or using this specifica-tion to evaluate or accredit the agency.3.2.11 verification, na process that establishes whether theresults of a previously calibrated measurement instrument,measurement system, or material measure are
29、stable.3.2.11.1 DiscussionVerification is used to maintain thetraceability of a measurement and to determine when torecalibrate. Control charts are often used to plot verificationresults and determine if instrument measurements have driftedout of control.3.3 Other Definitions:3.3.1 Refer to Terminol

Significance and Use4.1 This specification provides the basic minimum criteriafor use in evaluating the qualifications of testing or inspectionagencies, or both, for road and paving materials. The criteriamay be supplemented by more specific criteria and require-ments. An individual user c
31、an also use it to judge thequalification of an agency.4.2 The intent of this specification is to provide a consensusbasis for evaluating a testing or inspection agency, or both,with respect to that agencys capability to objectively andcompetently provide the specific services needed by the user.4.3
32、This specification can be used as a basis for accredita-tion.5. Responsibilities and Duties5.1 The agency shall ensure that only inspections or tests forwhich it is adequately equipped and staffed are performed.5.2 The agency shall ensure that personnel perform onlyinspections and tests for which th

34、ce with appropriate standards and quality controlcriteria. Documents unique to the user shall be furnished to theagency.6. General Capabilities6.1 Laboratory TestingThe laboratory testing services of aroad and paving materials testing agency shall include some orall of the following capabilities:6.1
35、.1 Testing of road and paving materials and mixtures inthe laboratory,6.1.2 Testing of aggregate for compliance with specificationrequirements,6.1.3 Preparation and evaluation of mix design in accor-dance with the proper method common to the geographicalarea in which it offers services or in accorda
36、nce with theappropriate ASTM or AASHTO standard procedure,6.1.4 Determination of percent binder and gradation of plantaggregates in plant mix, and6.1.5 Determination and verification of mix properties forcomparison with the mix design.6.2 Field Testing and InspectionThe field services of aroad and p
37、aving materials testing and inspection agency shallinclude some or all of the following capabilities:6.2.1 Investigation of aggregate at the source for compli-ance with specification requirements,6.2.2 Inspection of proportioning and mixing at the plant orproject site in accordance with users requir
38、ements.6.2.3 Inspection of handling, laying, and rolling operationsof the mixture at the site,6.2.4 Determination of thickness of compacted mixture, and6.2.5 Determination of density and the percent compactionof a bituminous pavement after construction.NOTE 1Since the requirements for construction c
39、ontrol can varywidely from project to project depending upon the nature of the mixture,location, and intended use of the bituminous mixture in the project, thecapability of the agency for testing and inspection should be that necessaryto accomplish construction control of the users specific project
