4) Durability of Effects

Members should obtain data regarding the products' durability of effects (through acceleration and exposure tests), and maintain conditions in which the data can be disclosed to customers and interested parties. JIS tests should be conducted to test acceleration tests carried out by members, and the products need to meet the standards for determining performance.

However, it is not obligatory that members carry out JIS tests after conducting exposure tests.

5) Safety

In order to obtain product certification, the members should evaluate their products' safety based on safety tests using the products, compositional materials' MSDS and other items, and confirm that the products meet the following safety standards.

⚫Mandatory Test Items
1) Peroral Acute Toxicity: LD50 ≥ 2,000mg/kg
2) Primary Skin Irritation Test: No Irritation or mild irritation
3) Mutation Test: Negative mutagenicity

Also, additional confirmation of the following item is needed for products that may normally be used in a state in which they have long-term, direct skin contact.

4) Skin Sensitization Test: Negative

Supplementary Note:

Photocatalyst products described in these standards for determining performance are end products to which photocatalyst is applied and processed.

Labeling methods for photocatalyst products and their contents depend on items stipulated by the standards operation committee.

3) Standards for Determining Performance

In order to obtain product certification, products should meet the following initial performance requirements for two types of bacteria which are stipulated by JIS.

(Photocatalyst Antibacterial Finishing Products: Film Contact Method)
  • RL ≥ 2.0 (UV Luminous Intensity: Required Value) *
  • ◿R ≥ 0.3 (UV Luminous Intensity: Required Value)*
(Photocatalyst Antibacterial Finishing Fiber Products: Glass Contact Method)
  • SL ≥ 2.0 (UV Luminous Intensity: Required Value) *
  • ◿S ≥ 0.3 (UV Luminous Intensity: Required Value)*

* "UV Luminous Intensity: Required Value" is the intensity of ultraviolet rays at locations where applicable products are supposed to be used or applicable products claim to produce photocatalystic antibacterial effects.

4) Durability of Effects

Members should obtain data regarding the products' durability of effects, and maintain conditions in which the data can be disclosed to customers and interested parties. The members should conduct JIS evaluation tests after carrying out tests (acceleration and exposure tests) in which the durability of effects, such as the endurance that applicable products claim to have, are evaluated, and confirm that the products meet "3) Standards for Determining Performance."

5) Safety

In order to obtain product certification, the members should evaluate their products' safety based on safety tests using the products, compositional materials' MSDS and other items, and confirm that the products meet the following safety standards.

⚫Mandatory Test Items
1) Peroral Acute Toxicity: LD50 ≥ 2,000mg/kg
2) Primary Skin Irritation Test: No Irritation or mild irritation
3) Mutation Test: Negative mutagenicity

Also, additional confirmation of the following item is needed for products that may normally be used in a state in which they have long-term, direct skin contact.

4) Skin Sensitization Test: Negative

Supplementary Note:

Photocatalyst products described in these standards for determining performance are end products to which photocatalyst is applied and processed.

Labeling methods for photocatalyst products and their contents depend on items stipulated by the standards operation committee.
