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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

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.

ISO 13629-1 was prepared by Technical Committee ISO/TC 38, Textiles.

ISO 13629 consists of the following parts, under the general title Textiles — Determination of antifungal activity of textile products:

• Part 1: Luminescence method
• Part 2: Plate count method (under preparation)

Introduction

Speciality products of antimicrobial-treated textiles have been increasing year by year in various applications and they certainly contribute to the prevention of a material’s deterioration and to the improvement of the environment and quality of life.

For these reasons, ISO/TC 38/WG 23 developed ISO 20743 in 2007, and is continuing to study a test method on the antifungal activity of textile products for a series of International Standards.

This part of ISO 13629 adopts an ATP luminescence method as a basis for the quantitative determination of antifungal activity.

Characteristics of the luminescence method are as follows:

• extremely small margin of error compared to the colony count method;
• elimination of the culturing time for colony formation, enabling a shorter testing time;
• simplification of testing operation.

The other parts will be developed relating to:

• Part 2: Plate count method.

1 Scope

This part of ISO 13629 specifies a test method for the quantitative determination of the antifungal activity by measuring the intensity of luminescence produced by an enzymatic reaction [adenosine triphosphate (ATP) method].

The part of ISO 13629 is applicable to various kinds of textile products, such as fibres, yarns, fabrics, clothing, bedclothes, home furnishings and other miscellaneous goods.

Based on the intended application and on the environment in which the textile product is to be used, the user can select the most suitable evaluation method from the following methods before enumeration by the ATP method:

• a) absorption method (an evaluation method in which test fungi suspension is inoculated directly onto the specimens);
• b) transfer method (an evaluation method in which test fungi are placed on an agar plate and printed onto the specimens).
