(a) Upon completing investigation of a complete assembly of an
electrical machine or accessory, MSHA will issue to the applicant either a
written notice of approval or a written notice of disapproval, as the case
may require. No informal notification of approval will be issued. If a
notice of disapproval is issued, it will be accompanied by details of the
defects, with recommendations for possible correction. MSHA will not
disclose, except to the applicant, any information upon which a notice of
disapproval has been issued.
(b) A formal notice of approval will be accompanied by a list of
drawings, specifications, and related material, covering the details of
design and construction of the equipment upon which the approval is based.
Applicants shall keep exact duplicates of the drawings, specifications, and
descriptions that relate to equipment for which an approval has been issued,
and the drawings and specifications shall be adhered to exactly in production
of the approved equipment.
(c) An applicant shall not advertise or otherwise represent his
equipment as approved (permissible) until he has received MSHA's formal
notice of approval.
