Sec. 18.12  Letter of certification.

    (a) A letter of certification may be issued by MSHA for a component 
intended for incorporation in a complete machine or accessory for which 
an approval may be subsequently issued. A letter of certification will 
be issued to an applicant when a component has met all the applicable 
requirements of this part. Included in the letter of certification will 
be an assigned MSHA certification number that will identify the 
certified component.
    (b) A letter of certification will be accompanied by a list of 
drawings, specifications, and related material covering the details of 
design and construction of a component upon which the letter of 
certification is based. Applicants shall keep exact duplicates of the 
drawings, specifications, and descriptions that relate to the component 
for which a letter of certification has been issued; and the drawings 
and specifications shall be adhered to exactly in production of the 
certified component.
    (c) A component shall not be represented as certified until the 
applicant has received MSHA's letter of certification for the component. 
Certified components are not to be represented as ``approved'' or 
``permissible'' because such terms apply only to completely assembled 
machines or accessories.
