Terminology3.1 Definitionsor definitions and terms commonly used in ASTM standards, including this standard, refer to TerminologyD1356. For an explanation

24、of units, symbols, and conversion factors, refer to Practice D1914.3.2 Definitions of Terms Specific to This Standard:3.2.1 chamber loading ratiothe total amount of test specimen divided by the net air volume of the environmental test chamberin 1/m3, m/m3, m2/m3, and m3/m3 for unit, line, area, and

25、volume emission sources, respectively (see 3.2.43.2.5).3.2.2 clean airdefined in this practice as air that satisfies all of the following criteria:(1) concentrations of total VOCs 10 g/m3;(2) concentration of any individual compound to be measured 2.0 g/m3;(3) particle concentrations 100 particles/f

26、t35,200 particles/m3 of 0.5 m diameter or larger (that is, the ISO Class M26according to ASHRAE 1995 ISO 14644; (1) clean room requirement for 0.5 m diameter particles;(4) concentrations of ozone and other potentially reactive species such as nitrogen oxides (NOx) and sulfur oxides (SOx) shouldbe at

27、 or below detectable levels (for example, 0.50.5 m diameter particles ASHRAE 1997c particles, (16) , and8.1.1.4 ozone and other potentially reactive species (NOx, SOx, etc.) should be at or below their detectable levels (for example,each reactive compound 0.9). However, its validity for extrapolatin

28、g the test results to a time beyond the test period depends on how well the emissionprocess is physically described by the model. In a product-specific test protocol, the emission characteristics of the specific producttype should be used to specify the time period within which the model is valid.12

29、. Report of the Test Results12.1 The report should generally include the following information:12.1.1 Testing ObjectivesThe purpose of the testing project and intended use of the results.12.1.2 Testing Laboratory IdentificationThe name, address, phone/fax numbers, and contact person.12.1.3 Product I

30、dentificationThe name, specific identifiers from the manufacturer, and a brief description of the product, itsapplication, and history.12.1.4 The procedure of collecting, packaging, handling, shipping, and storage of material samples.12.1.5 Facility and Equipment IdentificationA general description

31、of the facilities and equipment, including chemicalsampling and analysis.12.1.6 Test ConditionsIncluding temperature, humidity, air change rate, and dimensions of the test specimen.12.1.7 Results(1) names of VOCs identified in the prescreening analysis; (2) basis of selecting the individual VOCs for

32、environmental chamber testing; (3) concentration versus time data; and (4) emission factors calculated and/or the selected modeland its coefficients for TVOCs and selected individual VOCs. The report should clearly state all of the sampling, recovery, andanalytical conditions relating to the determi

33、nation of all analytes, as well as the method of calculating TVOC values.NOTE 9The TVOC value is a method-dependent measurement. When reporting TVOC values, the user of this practice should indicate themeasurement method used, including a detailed description of the adsorbents employed, the sampling

34、 volume, instruments, and analytical conditions. Itis recommended that the VOC range, expressed as vapor pressure (v.p.) at 25 C, of a given method be reported in parentheses with TVOC results; forexample, TVOC-by-GC/MS (v.p. 150 to 0.3 kPa) = 10 mg/m3.NOTE 10The European Union and WHO define VOCs b

35、y different criteria. The WHO definition is based upon boiling point; whereas, the EUdefinition contains a specific list of 64 compounds. The definition in Terminology D1356 may exclude some of the VOCs listed by the European Union(for example, 4-phenylcyclohexene, 2-butoxyethoxyethanol, and some of

36、 the higher boiling n-alkanes).12.1.8 ReferenceRefer to this practice and others as appropriate.12.2 Report all values in SI units unless specified otherwise.13. Quality Control and Quality Assurance13.1 Quality Assurance/Control (QA/QC) PlanAQA/QC plan should be designed and implemented to ensure t

37、he integrity ofthe measured and reported data obtained during product evaluation studies. This plan should encompass all facets of themeasurement program from sample receipt to final review and issuance of reports.13.2 Data Quality Objectives/Acceptance CriteriaThe QA/QC plan should be based on esta

38、blished data quality objectives andacceptance criteria that will depend on the purpose of the testing and the capability of the laboratory (equipment and personnel)to conduct the test procedures. Data quality objectives should be established for the following parameters prior to initiating thetestin

39、g program:13.2.1 Test Material/Product Transfer Time and Environmental ConditionsTolerance limits should be established for theelapsed time from production to testing under an acceptable range of specified environmental conditions.13.2.2 Test Chamber Conditions and Test ResultsPrecision and accuracy

40、 limits should be established for each parameter inTable 2.Accuracy certifications are supplied by the manufacturers of the sensors who calibrate them against National Institute ofStandards and Technology (NIST)-traceable primary sources.Accuracy checks are performed with independent sensors calibra

41、ted against NIST-traceable primary standards. Precisionmeasurements are obtained in the laboratory by continuous recording of the parameters. Non-compliance requires immediatecorrection and/or replacement of sensors. Calibrated replacements should be retained in the laboratory. Experience shows that

42、routine calibration and tracking of precision can prevent non-compliance.13.2.3 Record Keeping and LogsVarious documentation requirements shall be implemented for all test parameters includingenvironmental chamber and analytical performance. Many of these are identified in Guide D5116. Additionally,

43、 the identity ofpersons conducting each procedure shall be recorded. All devices used, date and time of tests, and the test data should be part ofQA/QC recording process. Completeness of records demonstrates the care and attention given to the QC process.D6670 132113.3 CalibrationCalibration must be

44、 frequent enough to ensure performance of the system within specified parameters.Frequency of calibration should be determined prior to the test, and periodic equipment checks should verify the acceptableperformance. All calibration and verification measurements should be recorded including the time

45、, equipment description, andmeasurement data.13.4 Accuracy DeterminationsAccuracy determinations require measurements of a known emission source (for example,permeation tubes, spiked samples) or test gas. These measurements should be made prior to establishing the project data qualityobjectives, and

46、 shall be consistent with the overall testing objectives. The procedures and materials used for establishing theaccuracy of the measurement system should be recorded.13.5 PrecisionPrecision determinations require replications sufficient to establish the systematic variation associated with allmeasur

47、ements. When multiple chambers are used as part of an experiment, duplicate samples shall be used. Variation in test datafrom a single chamber and among chambers can be established by use of standardized sources such as permeation tubes fordetermining organic concentrations and calculated emission r

48、ates.13.6 Duplicate AnalysisNo fewer than 15 % of the air samples collected should be subject to duplicate analysis. The resultsof such analyses shall be recorded and assessed to determine the adequacy of the total system performance relative to the testingobjectives.13.7 ChartingCharting QC data wi

49、ll allow analysis of system performance and observation of anomalistic or unacceptabledeviations.14.
