This document specifies the test method that measures the mass per unit area of a nonwoven.
SI values are regarded as the official standard system of measurement for this standard procedure. If other systems of measurement are used in place of SI units, their values must be reported independently. Systems of measurement must not be combined in any way, but shall be regarded and reported separately.

This document specifies a test method for the determination of the breaking force and elongation of nonwovens using a strip method in conditioned or wet state. This test method describes two procedures, Option A and Option B, for carrying out nonwoven material tensile tests. These two procedures use two types of specimens which are listed below, and three alternative types of testing machines are also listed below. CRE is the instrument of choice.
Type of specimen:
a) Option A – 25 mm strip tensile
b) Option B – 50 mm strip tensile
Style of tensile testing machine:
a) Constant-rate-of-extension (CRE)
b) Constant-rate-of-load (CRL)
c) Constant-rate-of-traverse (CRT)
SI values are regarded as the official standard system of measurement for this standard procedure. If other systems of measurement are used in place of SI units their values must be reported independently. Systems of measurement must not be combined in any way, but shall be regarded and reported separately.
NOTE INDA has sponsored studies comparing both options A and B. Studies indicated that if option A was performed using option B’s 50 mm wide material, the result for both options would harmonize, giving the same results, regardless of the other machine settings.

This document is a method for determining the total content (solvent extractible) of the following bisphenols in leather:
— bisphenol A;
— bisphenol B;
— bisphenol F;
— bisphenol S.
This method requires the use of liquid chromatography (LC) with triple quadrupole mass spectrometer (MS/MS) or with ultraviolet (UV) detector or with Diode Array Detector (DAD) or with Fluorescence Detector (FLD) to identify and quantify the bisphenols.
NOTE 1 This method can also be used for other bisphenols if they are validated by the laboratory.
NOTE 2 The main difference between LC-MS/MS and LC-UV, LC-DAD or LC-FLD is the quantification limit (9.2).

This guideline provides a list of recommended tests that can be used to assess the quality of chemicals used in tanning process.
This guideline applies to chemicals whose application has the same effect on leather, grouped in families.

This document specifies a test method for the determination of the strike- through time (STT) for each of three subsequent doses of liquid (simulated urine) applied to the surface of a test specimen of nonwoven coverstock. The STT is defined as the time taken for a known volume of liquid to pass through the nonwoven that is in contact with an underlying dry standard absorbent pad.
This test method is intended for Quality Control and is designed for comparison of STT for different nonwoven coverstocks. It does not simulate in-use conditions for finished products.
SI values are regarded as the official standard system of measurement for this standard procedure. If other systems of measurement are used in place of SI units (including inch-pound), their values must be reported independently. Systems of measurement must not be combined in any way, but shall be regarded and reported separately

This document specifies a test method for the determination of the ability of diaper coverstock to resist the transport back onto the skin of a liquid which has already penetrated the coverstock.
This test corresponds with Repeated Liquid Strike-Through Time - NWSP 070.7.
This test method is intended for Quality Control and is designed for comparison of wetback for different nonwoven coverstocks and treatments. It does not simulate in use conditions for finished products.
SI values are regarded as the official standard system of measurement for this standard procedure. If other systems of measurement are used in place of SI units (including inch-pound), their values must be reported independently. Systems of measurement must not be combined in any way, but shall be regarded and reported separately.

This document specifies a method for the determination of the resistance of rubber- or plastics-coated fabrics to blocking.
The method specified is acceptable in most cases. lf it is desired to use conditions other than those specified, these may be mutually agreed between the contracting parties but such variations shall be stated in the test report.
