(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.
(3) An applicant may request testing and evaluation to non-MSHA product safety standards which have been determined by MSHA to be equivalent, under § 6.20 of
this chapter, to MSHA's product approval requirements under this part.
(b) The application shall specify the operating conditions (see
§33.22) for which certification is requested.
(c) Shipment of the equipment to be tested shall be deferred until

detail to identify fully the design of the unit or system and to disclose its
materials and detailed dimensions of all component parts. Drawings must be
numbered and dated to insure accurate identification and reference to
records, and must show the latest revision. Specifications and drawings,
including a complete assembly drawing with each part that affects dust
collection identified thereon, shall include:
(1) Details of all dust-collector parts. A manufacturer
who supplies the applicant with component parts or sub- assemblies may submit
drawings and specifications of such parts or subassemblies direct to MSHA
instead of to the applicant. If the unit or system is certified, MSHA will
supply the applicant with a list, in duplicate, of drawing numbers pertaining
to such parts or subassemblies for identification purposes only.
(2) Details of the electrical parts of units designed to
operate as face equipment (see §33.38) in accordance

unit or a combination unit that includes electrical parts, and is designed
to operate as electric face equipment, as defined in §33.38, the application shall be in triplicate.
(f) The application shall state that the unit or system is completely
developed and of the design and materials which the applicant believes to be
suitable for a finished marketable product.
(g) The applicant shall furnish a complete unit or system for
inspection and testing. Spare parts, such as gaskets and other expendable
components subject to wear in normal operation, shall be supplied by the
applicant to permit continuous operation during test periods. If special
tools are necessary to disassemble any part for inspection or test, they
shall be furnished by the applicant.
(h) Each unit or system shall be carefully inspected before it is
shipped from the place of manufacture or assembly and the results of the
inspection shall be recorded on a factory-inspection form. The applicant
shall furnish MSHA with a copy of the factory-inspection form with his
application. The form shall direct attention to the points that must be
checked to make certain that all parts are in proper condition, complete in
all respects, and in agreement with the drawings and specifications filed
(i) With the application the applicant shall furnish MSHA with
complete instructions for operating and servicing the unit or system and
information as to the kind of power required. After MSHA's investigation, if
any revision of the instructions is required a revised copy thereof shall be
submitted to MSHA for inclusion with the drawings and specifications.
