UL certified

At the same time as being a certification body (profit organization), it is a certification name performed by our company as a standard in state law. In the pre-stage of electrical products, from materials to final products, we set standards for functions and safety, formulate evaluation methods at the same time, and actually carry out evaluation tests.

Although it is not a national institution, some states require it as a basis for machine safety, and when it is distributed in the United States, certification is effectively required.

For details of UL, please refer to the homepage of the relevant organization.

The application process is as follows:

1. Estimate
2. Scope Letter is a document necessary for formulating and estimating a test program.
Notification of samples, evaluation period, applicable standards
3. Sending materials and samples from the client and conducting product evaluation by UL
4. After analyzing the report and incorporating it into the design, apply for this certification (issue of preliminary evaluation report by UL)

* Since the required inspection items differ depending on the product, it seems that explanation is unnecessary (causing extra confusion).

UL certification includes the "listing mark" currently attached to final products and the "recognized component mark" attached to components (parts and materials of final products) that do not function or are restricted by themselves, mainly. Used in medical and industrial equipment, the products unique properties are inspected, evaluated and certified for use under specific conditions and for withstand predictable accidents. There is an application mark.

In addition, there may be a letter on the left and right of the mark (“C” on the left or “C” on the left and “US” on the right), but the “C” is certified in Canada, “US”, respectively. The description of is intended to be certified in the United States, and the one with "C" means that it is certified in Canada, and the one with "C" and "US" means that it is certified in both the United States and Canada.
