3Tear Strength Tearing Strength Standards involved: ISO /2; ASTM D1424; ASTM D2261; ISO ; BS EN ISO 4674, etcApparatus involved: Elmendorf Tester or Universal Strength Tester –CRE;The tearing strength is maximum force needed to continue tearing of a fabric that has a pre-cut opening in the specimen.
4Tensile Strength / Elongation Tensile Strength / Elongation at BreakStandard involved: ASTM D 5034; ASTM D2209; BS EN ISO 3376; BS EN ISO & 2, etcApparatus involved: Universal Strength Tester –CREThe tensile strength is determined by a force at a constant rate of extension to a fabric sample held in place by one fixed and one moveable jaw. The force required for a break in the fabric is recorded. The elongation at break is also recorded by the strength tester.
5Seam Strength / Slippage Standard involved: ASTM D1683; JIS L1093; ISO /2, BS EN 13572Apparatus involved: Universal Strength Tester –CREThe seam strength is determined by stretching a seam aligned midway between the gripping jaws, the maximum force before seam breakage is recorded. Seam slippage is similar to seam strength, instead that the force is measured when the seam has slipped to a defined displacement. The seam is not ruptured in the process
6Bursting Strength Bursting Strength Standard involved: ASTM D3786; ASTM D3787; JIS L1096; BS EN ISO & 2, etcApparatus employed: Hydraulic or Pneumatic Burst Testers and Ball Burst TesterThe specimen is clamped in a holder, a distension force, either by means of hydraulic, pneumatic, or mechanical means, is applied on the specimen until it ruptures. The bursting force is the maximum force recorded during the course of testing
7Water Repellency/Resistance AATCC 22 Spray TestApparatus employed: Spray tester,The test procedure involves applying water to a specimen surface, using gravity. The after-test specimens are then assessed for amount and degree of surface wetting observed
8Water Repellency/Resistance AATCC 35 Rain TestApparatus employed: Rain TesterThe test procedure involves applying water to a specimen surface, under pressure. A blotting paper is behind the tested specimen during the test. The amount of water that penetrates the fabric and is absorbed by the blotting paper is measured after the test.
9Odor Determination Principle The odor test indicates potential odor problems.MarketEUUSASChinaJapanTest MethodRef. SNVFed. Std. 148a Method 11N/AGB/T14272JIS L1093General Requirement<3<2
10Odor DeterminationThe odor test is performed with reference to SNV The test specimen (40g) is placed on top of 300ml sodium carbonate solution and kept in a closed container. The container is put it into a oven set to a temperature of 37 +/-2°C for 15 hours.Six people (minimum) are required to independently judge the odor intensity and rate it according to the following nomenclature:Intensity ScalesGrade 1 – odorlessGrade 2 – weak odorGrade 3 – tolerable odorGrade 4 – annoying odorGrade 5 – intolerable odor

12Liquid Repellency Principle To determine the degree to which a mixture of water and alcohol would be absorbed into a fabric.AATCC Test Methods 193Liquids composed of different combinations of water and alcohol are dropped onto the surface of a fabric. The time it takes to be absorbed into the fabric is observed. The rating is the number that has been assigned to the liquid that is not absorbed into the fabric.
13Moisture Management Principle To determine the moisture management characteristics of a fabric as a moisture management indexAATCC Test Methods 193The results of the test are used to determine a moisture management index that is based on water resistance, water absorption and transport characteristics and wicking properties of the fabric structure including the fibers and yarns.
14WickingPrincipleTo determine the degree to which a liquid moves up the length of a fabricFabrics are suspended in a measured depth of water and the distance that the water travels up the fabric specimen is measured over time.Indication of moisture transport away from a source.
15Drying RatePrincipleTo determine the rate at which a fabric will dry when wetted by waterFabrics are wetted with a fixed amount of liquid and then exposed to heat. The drying rate of the fabric is determined by measuring the change in weight over time.Indication of moisture transport away from a source.
16Water Repellency/Resistance AATCC 127 Hydrostatic Pressure TestApparatus employed: Hydrostatic head testerThe test procedure involves applying water under the surface of a fabric and measuring the amount of pressure it takes to force water through the fabric. The pressure to force 5 drops of water through the fabric is determined.
17Air Permeability Air Permeability Standard involved: ASTM D737; BS EN ISO 9237; JIS L1096, etcApparatus employed: Air Permeability TesterThe sample is secured on the permeability tester. The tester then generates an air pressure gradient across both sides of the sample. The faster the rate of pressure gradient degeneration, the higher is the air permeability of the sample
