Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Conditioning atmospheres and physical tests for textile fabrics.
This second edition cancels and replaces the first edition (ISO 13938-2:1999), of which it constitutes a
minor revision.

INTERNATIONAL STANDARD ISO 13938-2:2019(E)
Textiles — Bursting properties of fabrics —
Part 2:
Pneumatic method for determination of bursting strength
and bursting distension
1 Scope
This document describes a pneumatic pressure method for the determination of bursting strength and
bursting distension of textile fabrics.
NOTE ISO 13938-1 describes a method using hydraulic pressure.
The method is applicable to knitted, woven, nonwoven and laminated fabrics. It can be suitable for fabrics
produced by other techniques. The test is suitable for test specimens in the conditioned or wet state.
From the available data there appears to be no significant difference in the bursting strength results
achieved using hydraulic or pneumatic burst testers, for pressures up to 800 kPa. This pressure range
covers the majority of performance levels expected of general apparel. For speciality textiles requiring
high bursting pressures, the hydraulic apparatus is more suitable.
