ISO 32100-2010 pdf download.Rubber-or plastics-coated fabrics – Physical and mechanical tests – Determination of flex resistance by the flexometer method.
This International Standard specifies a test method for determining the flex resistance of rubber- or plastics-coated fabrics in the folded condition. The test method is applicable only to products which can be clamped in the test apparatus used and to products with which the fold made in the test specimen can be caused to move back and forth along the specimen during the test.
The appearance of the test specimen, after completion of either the flex number (see 3.1) or a specified number of flex cydes, is taken as a measure of the flex resistance in the folded condition.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 flex number
number (agreed between the interested parties) of flex cycles to which the test specimen is subjected, the specimen being subsequently examined using a magnifying lens with x6 magnification to determine whether any damage or other visible change is observable
3.2 flex cycle
cycle comprising one forward and one backward (i.e. a complete to-and-fro) movement of the moveable clamp of the test apparatus.ISO 32100 pdf download.
