17、Specification for Agencies Engaged in ConstructionInspection, Testing, or Special InspectionE1301 Guide for Proficiency Testing by InterlaboratoryComparisons3. Terminology3.1 DefinitionsThe approved standard definitions arelisted below.3.1.1 quality system, nthe organizational structure, re-sponsibi
18、lities, procedures, 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 specificati
19、on 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 provide inspections or tests; or using this specification toevaluate or accredit the agency.3.2.4 calibration, na process that establishes
20、the relation-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 ofequ
21、ipment, such 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 instrumentm
22、easurements 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
23、 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 documentsdescribing an agencys quality system.3.2.7 standardization, na process that determines whetheradjustments are needed to a specific piec
24、e 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 result of a measure-ment whereby it can be related to stated references, usuallynational or international standards, through an unbrok
25、en chainof 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 r
26、egular 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 values that couldbe attributed to the measured quantity.3.2.9.1 DiscussionThe uncertainty of a measurement isrequired in order to establ
27、ish its traceability. 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 agen
28、cy.3.2.11 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. Contro
29、l 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 Terminology D8.4. Significance and Use4.1 This specification provides the basic minimum criteriafor use in evaluating the qualifications of tes
30、ting or inspectionagencies, 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 evaluatin
31、g 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 This specification can be used as a basis for accredita-tion.5. Responsibilities and Duties5.1 The agency shall ensure that only inspec
32、tions 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 ensure that all e
33、quipment 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 Capabilities6

35、rements,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 pla
36、nt 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 aggregate a
37、t 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 compa
38、cted 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 mix
39、ture 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. Personnel Qualifications7.1 Management and SupervisionThe testing and inspec-tion services of the agency shal
40、l be under the direction of aperson charged with scientific or engineering managerial re-sponsibility. This person should be a licensed engineer and afull-time employee of the agency and shall have a minimum of5 years experience in inspecting and testing of road and pavingmaterials and construction;
41、 however, in place of being alicensed engineer, a person with equivalent science-orientededucation and experience in having satisfactorily directedtesting or inspection services, or both, of road and pavingmaterials is acceptable. This person shall possess all applicableprofessional licenses or cert
42、ificates required by public law orrequirements of the authority in one or more fields which theperson directs.ANICET Level IV Certification in ConstructionMaterials TestingSubfield Asphalt would be considered anexample of an acceptable certification of the experience of thisindividual.NOTE 2The Nati
