Secondary effects of antibacterial efficacy such as fungal resistance, odour prevention and biodeterioration are not covered by this standard.

NOTE 1 For the product so determined that the test method for textile products should be applied from their usage, shape, etc, clause 10 (Quantitative test) of JIS L 1902 may be applied.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 22196 : 2007 Plastics – Measurement of antibacterial activity on plastics surfaces (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS and IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.

This Standard is applicable to plastic products, metal products, ceramic products and the like, and does not cover textiles, soft foamed materials such as sponges, and products utilizing such materials.

This Standard is applicable to all textile products, including cloth, wadding, thread and material for clothing, bedclothes, home furnishings and miscellaneous goods, regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting).

Based on the intended application and on the environment in which the textile product is to be used and also on the surface properties of the textile properties, the user can select the most suitable of the following four determination methods on determination of antibacterial activity.

a) Absorption method An evaluation method in which test bacterial suspension is inoculated directly onto the specimens.

b) Transfer method An evaluation method in which test bacteria are placed on an agar plate and transferred onto the specimens.

c) Printing method An evaluation method in which test bacteria are placed on a filter and printed onto specimens.

d) Halo method A qualitative method to evaluate by the existence of halo

The colony plate count method and the ATP (ATP = Adenosine Tri-phosphate) luminescence method are also specified for measuring the enumeration of bacteria.

The evaluation of photocatalytic antibacterial efficacy treated on the photocatalytic finished textile product shall be carried out according to JIS R 1702.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 20743: 2013 Textiles-Determination of antibacterial activity of textile products (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards andJIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according toISO/ IEC Guide 21-1.
