Textiles — bursting properties of fabrics

Part 1: Hydraulic method for determination of bursting strength and bursting distension.
National foreword.
This British Standard is the English language version of EN ISO 13938-1:1999. It is identicalwith ISO 13938-1:1999. Together with BSEN ISO 13938-2:1999, it supersedes BS 4768: 1972, which is with drawn.
The UK participation in its preparation was entrusted to Technical Сommittee TC1124, Physical testing of textiles, whichhas the responsibility to:
— aid enquirers to understand the text
— present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, andkeep the UKinterests informed;
— monitorrelated international andEuropean developments and promulgate them in the UK.
Alist of organizations represented on this committee can be obtained on request to its secretary.
Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications maybe found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application.
Compliance with a British Standard does not of itself confer immunity from legal obligations.

The text of EN ISO 13938-1:1999 has been prepared by Technical committee CEN/TC 248. “Textiles and textile product”, the secretariat of which is held by BSI, in collaboration with Technical committee ISO/TO 38 “Textiles”. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement at the latest by February 2000 and conflicting national standards shall be withdrawn at the latest by February 2000.
It is a revision of ISO 2960:1 974.
EN ISO 13938 is in two parts as follows:
prEN ISO 13938-1 Textiles — Bursting properties of fabrics — Part 1: Hydraulic method for determination of bursting strength and bursting distension (ISO/EDIS 13938-1:1998) prEN ISO 13938-2 Textiles — Bursting properties of fabrics — Part 2: Pneumatic method for determination of bursting strength and bursting distension (ISO/EDIS 13938-2:1998) NOTE: Normative references to International Standards are listed in annex ZA (normative). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This standard describes a hydraulic method for the determination of bursting strength and bursting distension of textile fabrics. In this part a hydraulic pressure is applied using a constant rate of pumping device.
NOTE prEN ISO 13938-2. describes a method using pneumatic pressure.
