| Japanese Standards | ![]() | JIS (Japanese industrial Standards / Japanese industrial standards) | Japanese standards established in accordance with the Industrial Standardization Act. The Industrial Standardization Act primarily consists of the establishment of JIS and the JIS marking system. The purpose of the JIS mark system is to enable users and consumers to obtain quality and peace of mind from products deemed JIS compliant. The Industrial Standardization Act was revised on June 9, 2004, and the fisJIS mark system was renewed on October 1, 2005. These revisions saw drastic changes, such as the transition of the product certification system from a national system to a private third party organization. |
|---|---|---|---|
| International Representative Standards | ![]() | UL (Underwriter's laboratories Inc.) | Established in 1894 as a non-profit organization in the U.S., it carries out approval tests for materials and products. The U.S. has no safety standards based on national laws unlike Japan, and UL approval, which is required by state laws and regions in many places, is indispensable for sales in the U.S. There are two types of certifications: listed and recognized. UL listed is meant for self-contained product. Others are recognized as UL Recognized products. |
![]() | CSA (Canadian standards Association) | It is a non-profit organization established in Canada in 1919 and carries out approval testing similar to UL. Like UL in the U.S., CSA certification is essential for sales in Canada. |
Notes on international standard products:
Terminals are approved as a combination of the terminal itself and the tool for crimping it.
Therefore, products using tools other than those specified will not be accepted as approved products. Furthermore, the use of specified tools only does not qualify for approval.
