The preparation before the test: test items must be in the normal temperature of 23 ℃ + 2 ℃, humidity, 50±5) % environment for 4 hours, and then the corresponding test. Test method: determination of tensile strength and elongation at break should be in accordance with the standard HG/T2580, specimen width of 50 mm, length is 350 mm, the fixture distance is 200 mm + / - 1 mm, stretching rate of 100 mm/min + 10 mm/min. Calculation results, accurate to 1 n tensile strength, elongation at break into integers. Tensile strength index for by the strength of 2100 n / 5 cm or more weft to a strength of 1600 n / 5 cm or more. The determination of tensile force should be in accordance with the standard HG/T2581 adopts double tongue single tear method, sample size is 225 mm long, wide 75 + 0. 5mm。 Test eligibility criteria: the extraction of three volumes product testing, a volume is unqualified, again from the original batch extraction volume 6, retest, if more than three volumes is unqualified, assesses this batch product is unqualified.
