21、3. Terminology3.1 DefinitionsThe approved standard definitions arelisted below. In addition, for information purposes only,Appendix X1 includes definitions for the terms verification,calibration, traceability, and uncertainty.3.1.1 quality system, nthe organizational structure, re-sponsibilities, pr
22、ocedures, activities, capabilities, and resourcesthat together aim to ensure that laboratory services satisfy datarequirements.3.2 Definitions of Terms Specific to This Standard:3.2.1 agency, nthe organization engaged to test or inspectroad and paving materials as required by a specification orcontr
23、act.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 provide inspections or tests; or using this specification toevaluate or accredit the agency.3.2.4 calibration, na process that establishes the relati
24、on-ship (traceability) between the results of a measurementinstrument, measurement system, or material measure and thecorresponding values assigned to a reference standard.3.2.4.1 DiscussionThe purpose of calibration is to estab-lish the traceability of a measurement on certain types ofequipment, su
25、ch as balances (measurement instrument) anddynamic shear rheometer (measurement system). Uncertaintyestimates obtained during calibration are used to judge if aninstrument is suitable for its intended purpose. There is a needto re-establish traceability or recalibrate only when instrumentmeasurement
26、s drift out of control (as determined throughverification of calibration).3.2.5 check, na specific type of inspection and/or mea-surement performed on equipment and materials to indicatecompliance or otherwise with stated criteria.3.2.5.1 DiscussionChecks are performed on items ofequipment that do n
27、ot make measurements, such as specimenmolds and ovens. Stated criteria can be dimensional tolerances.3.2.6 quality system manual (QSM), na set of documentsdescribing an agencys quality system.3.2.7 standardization, na process that determines whetheradjustments are needed to a specific piece of equip
28、ment, suchas pycnometers and flow meters, when its performance iscompared with that of a generally accepted standard.3.2.8 traceability, nthe property of a result of a measure-ment whereby it can be related to stated references, usuallynational or international standards, through an unbroken chainof
29、 comparisons all having stated uncertainties.3.2.8.1 DiscussionThere is a need for traceable measure-ments. Measurements, not the instrument, can be traceable.Measurement traceability is established through calibration.Measurement traceability is maintained through check ofcalibration (a regular che
30、ck of instrument output using acontrol standard).3.2.9 uncertainty, na parameter associated with the resultof a measurement that defines the range of the values that couldbe attributed to the measured quantity.3.2.9.1 DiscussionThe uncertainty of a measurement isrequired in order to establish its tr
31、aceability. The uncertaintyestimates obtained during calibration are used to judge if aninstrument is suitable for its intended purpose.3.2.10 user, nthe person or organization engaging theagency to provide inspections or tests; or using this specifica-tion to evaluate or accredit the agency.3.2.11
32、verification, na process that establishes whetherthe results of a previously calibrated measurement instrument,measurement system, or material measure are stable.3.2.11.1 DiscussionVerification is used to maintain thetraceability of a measurement and to determine when torecalibrate. Control charts a
33、re often used to plot verificationresults and determine if instrument measurements have driftedout of control.3.3 Other Definitions:3.3.1 Refer to Terminology D8.4. Significance and Use4.1 This specification provides the basic minimum criteriafor use in evaluating the qualifications of testing or in
34、spectionagencies, or both, for road and paving materials. The criteriamay be supplemented by more specific criteria and require-ments. An individual user can also use it to judge thequalification of an agency.4.2 The intent of this specification is to provide a consensusbasis for evaluating a testin
35、g or inspection agency, or both,3Withdrawn.D 3666 07a2with respect to that agencys capability to objectively andcompetently provide the specific services needed by the user.4.3 This specification can be used as a basis for accredita-tion.5. Responsibilities and Duties5.1 The agency shall ensure that
36、 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 they are adequately trained,qualified, and certified in accordance with applicable specifi-cations.5.3 The agency shall ensur
37、e that all equipment is properlymaintained in good operating condition and is calibrated asapplicable.5.4 The agency shall perform all testing and inspection inaccordance with appropriate standards and quality controlcriteria. Documents unique to the user shall be furnished to theagency.6. General C
38、apabilities6.1 Laboratory TestingThe laboratory testing services ofa road and paving materials testing agency shall include someor all of the following capabilities:6.1.1 Testing of road and paving materials and mixtures inthe laboratory,6.1.2 Testing of aggregate for compliance with specificationre
39、quirements,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 accordance with theappropriate ASTM or AASHTO standard procedure,6.1.4 Determination of percent binder and gradation of plantaggregates in
40、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 paving materials testing and inspection agency shallinclude some or all of the following capabilities:6.2.1 Investigation of aggregat
41、e 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 requirements.6.2.3 Inspection of handling, laying, and rolling operationsof the mixture at the site,6.2.4 Determination of thickness of co
42、mpacted mixture, and6.2.5 Determination of density and the percent compactionof a bituminous pavement after construction.NOTE 1Since the requirements for construction control can varywidely from project to project depending upon the nature of the mixture,location, and intended use of the bituminous
43、mixture in the project, thecapability of the agency for testing and inspection should be that necessaryto accomplish construction control of the users specific project or specialrequirements.7.
