There ISO 5084:, Textiles - Determination of the thickness of textiles and textile products (other than textile floor coverings, nonwovens and to those listed in ISO 5084 are specified in this part of ISO 9073. These are a) a different sampling procedure; b) specific pressures at which to test normal and bulky nonwovens; c) a specific area for the size of the presser-foot; d) a shorter time to note the gauge reading ili
