                      Subpart A_General Provisions

 

Sec.  36.12  Changes after certification.



    If an applicant desires to change any feature of certified 

equipment, he shall first obtain MSHA's approval of the change, pursuant 

to the following procedure:

    (a)(1) Application shall be made, as for an original certificate of 

approval, requesting that the existing certification be extended to 

cover the proposed change. The application shall be accompanied by 

specifications and related material as in the case of an original 

application.

    (2) Where the applicant for approval has used an independent 

laboratory under part 6 of this chapter to perform, in whole or in part, 

the necessary testing and evaluation for approval of changes to an 

approved product under this part, the applicant must provide to MSHA as 

part of the approval application:

    (i) Written evidence of the laboratory's independence and current 

recognition by a laboratory accrediting organization;

    (ii) Complete technical explanation of how the product complies with 

each requirement in the applicable MSHA product approval requirements;

    (iii) Identification of components or features of the product that 

are critical to the safety of the product; and

    (iv) All documentation, including drawings and specifications, as 

submitted to the independent laboratory by the applicant and as required 

by this part.

    (b) The application will be examined by MSHA to determine whether 

inspection and testing of the modified equipment or component or 

subassembly will be required. Testing will be necessary if there is a 

possibility that the modification may affect adversely the performance 

of the equipment. MSHA will inform the applicant whether such testing is 

required and the component, subassembly, and related material to be 

submitted for that purpose.

    (c) If the proposed modification meets the requirements of this 

part, a formal extension of certification will be issued, accompanied by 

a list of new and corrected drawings and specifications to be added to 

those already on file as the basis for the extension of certification.
