§2305.4. Approvals.

The conductors and equipment required or permitted by these orders shall be acceptable only if approved.

(a) When the term "approved" is used in these orders, it shall refer to products, materials, devices, systems, or installations that have been approved, listed, labeled, or certified as conforming to applicable governmental or other nationally recognized standards, or applicable scientific principles. The approval, listing, labeling, or certification of conformity, shall be based upon an evaluation performed by a nationally recognized testing laboratory recognized pursuant to 29 CFR 1910.7, which is incorporated by reference; or by a person, firm, or entity with appropriate registered engineering competence or by a person, firm, or entity, independent of the manufacturer or supplier of the product, with demonstrated competence in the field of such evaluation.

Exception: Where written approval by the Division is required in these orders.

(b) The Division may require proof in addition to that under (a) that the products, materials, devices, systems, or installations will provide reasonable safety under the conditions of use.

(c) When these orders require an approval of products, materials, devices, systems, or installations and that approval is not available under (a), it will be necessary to submit to the Division engineering calculations, stress analyses, and other data for each design, model, or make for which an approval is requested. The Division will then approve or disapprove the product, material, device, system, or installation as submitted or under specified conditions.
