QUALITY TESTING

The cornerstone of success is stringent quality control. Can you be sure the product you are wearing conforms to AS/NZS 4602.1? A certificate from a test house guarantees that the garment or fabric sent to the test house has attained the AS/NZS 4602.1 standard. It is not a guarantee that the bulk production meets the standard. Therefore, it is necessary that every roll of fabric and retro-reflective tape is tested with highly specialised equipment which guarantees that all production meets the AS/NZS 1906.4 standard.

Y

In the quality control laboratory the Minolta Spectrophotometer is used to check every roll of fabric. This guarantees that the fabric used is fully compliant to the AS/NZS 1906.4 standard. This graph displays the CIE 1931 X, Y chromaticity diagram which defines a colour space for graphing colour. Specifications for the colour space and luminance (brightness) are provided in the AS/NZS 1906.4 standard. The colour space is divided into 2 main classes - yellow and orange-red, with further divisions for certain application FABRIC TESTING
