Sec. 35.12  Changes after certification.

    If an applicant desires to change any specification or 
characteristic of a certified hydraulic fluid, he shall first obtain 
MSHA's approval of the change, pursuant to the following procedures:
    (a) 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(s) as in the case of an original 
application.
    (b) The application and related material(s) will be examined by MSHA 
to determine whether testing of the modified hydraulic fluid will be 
required. Testing will be necessary if there is a possibility that the 
modification may affect adversely the performance characteristics of the 
fluid. MSHA will inform the applicant in writing whether such testing is 
required.
    (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 specifications to be added to those already 
on file, as the basis for the extension of certification.
