Terminology3.1 For definitions of terms relating to Pile Floor Coverings,D13.21, refer to Terminology D5684.3.1.1 The following terms are relevant to this standard:backing, backing fabric, binding sites, carpet, change in surfaceappearance, durability, finished, finished pile yarn floor cover-in
21、g, floor covering, pile, pile yarn floor covering, resistance todelamination, soiling, textile floor covering, total mass, tuftbind, tuft element, tuft height, tufted fabric.3.2 For all other terminology related to textiles, refer toTerminology D123.4. Significance and Use4.1 This guide is useful to
22、 select test methods and orpractices that are commonly used in industry for evaluatingpile yarn floor covering. Refer to the particular test method orpractice cited for the property of interest for significance anduse statements.5. Sampling5.1 Sampling Units:5.1.1 Uncoated Floor CoveringThe basic sa
23、mpling unitof uncoated floor covering is a production roll.5.1.2 Coated Floor CoveringThe basic sampling unit ofcoated floor covering is a shipping roll. The number ofshipping rolls obtained from each production roll ranges fromone to over ten.5.2 Lot SampleIn quality acceptance and quality controls
24、ituations, take a lot sample as directed in Practice E122 whenstatistical knowledge of the product variability and test methodprecision is available and a decision has been made on themaximum deviation that can be tolerated between the estimateto be made from the lot sample and the result that would
25、 beobtained by measuring every sampling unit of the lot. Other-wise the number of sampling units is a lot sample and the useof the test results obtained from the individual test samplesshall be in accordance with the manufacturers Quality Controlprogram or with the specification agreed upon between
26、pur-chaser and the supplier.5.3 Laboratory Sampling UnitA laboratory sampling unitshall consist of full width section of floor covering cut fromone end of each roll in the lot sample and shall be at least 100mm (4 in.) longer than the specimens required for the test beingconducted. For coated pile y
27、arn floor covering exclude theseam end of a production roll.5.4 Test SpecimensFrom each laboratory sampling unit,take as many test specimens as directed by the procedure beingused that will yield a standard test result.6. Calibration6.1 Many of the test methods cited herein require the use ofproperl
28、y calibrated testing equipment. All testing systemsshould be verified before use. Refer to the individual testmethods for specific information on the preparation, calibra-tion, and verification of apparatus.7. Conditioning7.1 Condition the test specimens in the specific atmospheredetailed in the met
29、hod of interest. If a conditioning procedureis not specified, bring the test specimens to moisture equilib-rium in the standard atmosphere for testing textiles as directedin Practice D1776.8.
