This This Standard Standard was was prepa prepared red by the St anda andards rds Australi Australiaa Committe Committeee on Testin Testing g of  Textiles Textiles to superse supersede de AS 2001.2. 2001.2.4, 4, Deter Determin minatio ation n of burs bursting ting press pressure ure of textile textile  fabri cs . In the preparation of this Standard, the committee has recognized the need to revise certain aspects of the previous Standard relating to the specification of the clamping apertu aperture, re, type type of diaph diaphrag ragm, m, and fluid fluid flow rate. rate. Guide Guideline liness on calibra calibration tion and verification procedures of the unit using aluminium foil sheet are also incorporated. A separate Standard for determining the bursting force of textile fabrics (ball burst method) has been published AS 2001.2.19. In preparing this Standard, cognizance was taken of the following Standards: ISO 2960 Textiles—Determination of bursting strength and bursting distention—  Diaphragm  Dia phragm method  me thod  BS 4768 Method for the determination of the bursting strength and bursting distention of fabrics ASTM D 3786 Hydraulic bursting strength of knitted goods and non-woven fabrics:  Diaphragm  Dia phragm burstin burs tin g strength str ength tester tes ter met hod 

METHOD 1 SCOPE. COPE.

This Standard sets out two methods for determining the bursting pressure of both wet and dry fabrics. Method Method A—Constant A—Constant flow rate. rate. Method Method B—Constant B—Constant time to rupture. NOTE: The results obtained by the two methods may not be comparable.

The methods are applicable to all textile fabrics. They are particularly applicable to knitted and other fabrics for which breaking or tearing force determinations are not suitable. A method for the preparation of fabrics with an extensibility greater than that of the thin flexible diaphragm is given in Appendix A. 2 REFERENCE REFERENCED D DOCUMEN DOCUMENTS. TS.
