Sec. 18.6 Applications.
(a) Investigation leading to approval, certification, extension
thereof, or acceptance of hose or conveyor belt, will be undertaken by
MSHA only pursuant to a written application, in duplicate, accompanied
by a check, bank draft, or money order, payable to Mine Safety and
Health Administration to cover the fees. The application shall be
accompanied by all necessary drawings, specifications, descriptions, and
related materials, as hereinafter provided. The application, all related

(b) [Reserved]
(c) Applications for acceptance of a conveyor belt as fire resistant
shall include the following information: Trade name of the conveyor
belt, thickness of covers, friction and skim coats, number of plies,
type and weight of ply material, and designation of breaker strip or
floated ply. The applicant shall provide other description or
specifications as may be subsequently required.
(d) Applications for acceptance of hose as flame resistant shall
include the following information: Trade name of hose, identification of
materials used, including compound numbers, thickness of cover,
thickness of tube, and number and weight of plies. The applicant shall
provide other description or specifications as may be subsequently
required.
(e) Drawings, drawing lists, specifications, wiring diagram, and
descriptions shall be adequate in number and detail to identify fully
the complete assembly, component parts, and subassemblies. Drawings
shall be titled, numbered, dated and shall show the latest revision.
Each drawing shall include a warning statement that changes in design
must be authorized by MSHA before they are applied to approved
equipment. When intrinsically safe circuits are incorporated in a
machine or accessory, the wiring diagram shall include a warning
statement that any change(s) in the intrinsically safe circuitry or
components may result in an unsafe condition. The specifications shall
include an assembly drawing(s) (see Figure 1 in Appendix II) showing the
overall dimensions of the machine and the identity of each component
part which may be listed thereon or separately, as in a bill of material
(see Figure 2 in Appendix II). MSHA may accept photographs (minimum size
8 x 10\1/2\) in lieu of assembly drawing(s).
Purchased parts shall be identified by the manufacturer's name, catalog
number(s), and rating(s). In the case of standard hardware and
miscellaneous parts, such as insulating pieces, size and kind of
material shall be specified. All drawings of component parts submitted
to MSHA shall be identical to those used in the manufacture of the
parts. Dimensions of parts designed to prevent the passage of flame
shall specify allowable tolerances. A notation ``Do Not Drill Through''
or equivalent should appear on drawings with the specifications for all
``blind'' holes.
(f) MSHA reserves the right to require the applicant to furnish
supplementary drawings showing sections through complex flame-arresting
paths, such as labyrinths used in conjunction with ball or roller
bearings, and also drawings containing dimensions not indicated on other
drawings submitted to MSHA.
(g) The applicant may ship his equipment to MSHA for investigation
at the time of filing his application and payment of the required fees.
Shipping charges shall be prepaid by the applicant.
(h) For a complete investigation leading to approval or
certification the applicant shall furnish MSHA with the components
necessary for inspection and testing. Expendable components shall be
supplied by the applicant to permit continuous operation of the
equipment while being tested. If special tools are necessary to assemble
or disassemble any component for inspection or test, the applicant shall
furnish them with the equipment to be tested.
(i) For investigation of a hose or conveyor belt, the applicant
shall furnish samples as follows:
Hose--a sample having a minimum length of 2 feet;
Conveyor belt--a sample of each type 8 inches long cut across the entire
width of the belt.
(j) The applicant shall submit a sample caution statement (see
Figure 3 in Appendix II) specifying the conditions for maintaining
permissibility of the equipment.
(k) The applicant shall submit a factory-inspection form (see Figure
4 in Appendix II) used to maintain quality control at the place of
manufacture or assembly to insure that component parts are made and
assembled in strict accordance with the drawings and specifications
covering a design submitted to MSHA for approval or certification.
(l) MSHA will accept an application for an approval, a letter of
certification, or an acceptance for listing of a
[[Page 92]]
product that is manufactured in a country other than the United States
provided: (1) All correspondence, specifications, lettering on drawings
(metric-system dimensions acceptable), instructions, and related
information are in English; and (2) all other requirements of this part
are met the same as for a domestic applicant.
