New Austroads test methods on the evaluation of seamless knitted tubular filter fabric released

Wednesday, 15 November 2023

Austroads has published four new test methods that describe the procedure to be used when assessing seamless knitted tubular filter fabric.

Seamless tubular filter fabric is a type of filtration material that is constructed in a continuous tubular form without any seams or joints. This fabric is specifically designed for use in various filtration applications where a seamless structure is important for optimal performance. It is often used in construction and drainage .

ATM 821 details the procedure for determining whether a seamless tubular filter fabric pretreated in ultraviolet light will deweave, unravel or ladder when placed over a mandrel. ATM 822 provides instructions for the evaluation of abrasion resistance for seamless knitted tubular filter fabric. ATM 823 sets out the process for determining the weave stability of seamless knitted tubular fabric, while ATM 824 provides the method to determine the range of dimensions of openings among sample areas of seamless knitted tubular filter fabric.

“Test methods outline a more consistent approach to the testing of materials,” says Ross Guppy, Austroads Project Manager of Transport Infrastructure. “The release of new test methods represents an important step in the move to harmonise every aspect of contemporary construction practice across Australian and New Zealand”
