Mine Safety and Health Administration, the name of the complete 
assembly, the name of the applicant, and spaces for the approval number, 
serial number, and the type or model of machine.
    (2) An extension of approval will not affect the original approval 
number except that the extension number shall be added to the original 
approval number on the approval plate. (Example: Original approval No. 
2G-3000; seventh extension No. 2G-3000-7.)
    (b) The applicant shall reproduce the design on a separate plate, 
which shall be attached in a suitable place, on each complete assembly 
to which it relates. The size, type, location, and method of attaching 
an approval plate are subject to MSHA's concurrence. The method for 
affixing the approval plate shall not impair any explosion-proof feature 
of the equipment.
    (c) The approval plate identifies as permissible the machine or 
accessory to which it is attached, and use of the approval plate 
obligates the applicant to whom the approval was issued to maintain in 
his plant the quality of each complete assembly and guarantees that the 
equipment is manufactured and assembled according to the drawings, 
specifications, and descriptions upon which the approval and subsequent 
extension(s) of approval were based.
    (d) A completely assembled approved machine with an integral dust 
collector shall bear an approval plate indicating that the requirements 
of part 33 of this chapter (Bureau of Mines Schedule 25B), have been 
complied with. Approval numbers will be assigned under each part of such 
joint approvals.
