Textile Test Methods - Carpets - Determination of Tuft Withdrawal Force

This National Standard of Canada has been extended and reaffirmed by the CGSB Committee on Textile Test

Methods and Terminology. It is identical in content and in layout with International Standard ISO 4919, Carpets —

Determination of tuft withdrawal force, published 1978-10-01 by the International Organization for Standardization

(ISO), and is reprinted with the permission of ISO. The international standard was reviewed by the CGSB committee

to determine its suitability for Canadian use. It was agreed to use it in total, without editorial changes.

Throughout this standard, the words “National Standard of Canada” are to be understood as replacing the words

“International Standard” wherever they appear.

Some terminology and conventions are not identical to those used in other test methods within CAN/CGSB-4.2 —

Textile Test Methods. For example, the comma is used throughout this standard as a decimal marker rather than the point.

The following National Standard of Canada corresponds to the referenced ISO standard:

CANADA                           ISO

CAN/CGSB-4.2 No. 2       ISO 139

The referenced ISO 1957 standard has no Canadian equivalent.

The testing and evaluation of a product against this method may require the use of materials and equipment that

could be hazardous. This document does not purport to address all the safety aspects associated with its use.

Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither

assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed.
