1. Objective
This reference categorization table shows the concept of test categories, product examples, and reference
examples of test categories in order to assure the maximum possible level of consistency among member
companies and among products in performing the durability test defined in Terms 4, 5, 6, and 7: “VoluntarySpecifications for Quality and Safety” of the Rules and Detailed Rules of this society.
Definition of durability test
“Durability test” as used in this guideline refers to a series of tests for treating the products conferred withantibacterial, antifungal, and antiviral functions, etc. under preset conditions considering the environment
where such products are normally used before testing their functions, and does not assure functional durability
during actual use and product lifetime.
2. Points of Note in Operation
1) The durability test is positioned as preparation for evaluating the antibacterial, antifungal, or antiviral
activity which is necessary to register a product with SIAA.
2) The reference categorization table shows product examples and test categories from the point of view ofcustomers, in order to supplement the content (range) of application of the categories of waterproofing test
[Table 1] and light resistance test [Table 2].
3) The test categories are the guidelines for test conditions stipulated voluntarily by this society, and thecontent of this reference categorization table is not absolute.
4) As products are used in various ways, the application category may differ depending on the usage
environment and portion even in the case of an identical product.
5) The test categories are defined under the responsibility of the company that registers the product and cangrasp the actual condition of the product used. Additionally, the categories described in “VoluntaryRegistration Data Sheets Concerning Quality and Safety” shall be the same as the test conditions
implemented.
6) The content of this guideline may be reviewed and amended as needed.
7) This guideline does not restrict the specifications (standards) of the industrial associations and institutions
to which the member companies belong.
3. Durability Test (For details of test conditions, refer to test methods S08 and S09.)
Waterproofing test and light resistance test are set as durability tests.
4-1. Categories of Waterproofing Test
Assuming that the surface of a product conferred with antibacterial, antifungal, or antiviral function loses
its functionality and performance becomes deteriorated when in contact with water (or warm water), a test
according to the performance of the product (antibacterial, antifungal, or antiviral test) shall be implemented
after treating a test piece under the test conditions (water temperature and immersion time) specified forwaterproofing test categories.
Waterproofing test is classified into four categories, considering the degree of contact of the product withwater (Table 1).

4-2. Categories of Light Resistance Test
Light resistance test, in which a test according to the performance of the product (antibacterial, antifungal,or antiviral test) is implemented after treating a test piece under the test conditions (testing device andirradiation time) specified for light resistance test categories, based on the assumption that the performanceof a product conferred with antibacterial, antifungal, or antiviral function becomes deteriorated when it isexposed to light (in particular, ultraviolet ray), is classified into three categories considering the exposure of
the product to light (Table 2).
