b. Certificates of Conformance (COC). Only vehicle support stands that have been manufactured to
meet or exceed the safety guidelines of AMSE PALD Standards, Part 4 shall be purchased and
used. Local purchasers of commercial stands shall require suppliers of the stands to provide
proof of a qualified load test either from the manufacturer or a testing facility. Certificates of
Conformance (COC) with the load testing requirement by locally purchased stands will be
maintained by the unit.
c. Use of Straight Pins. The use of locally purchased stands that incorporate straight pins inserted
through the base and column to hold up the load is not recommended. Pin substitution is very
unsafe and happens frequently regardless of efforts to prevent it.
d. Product Marking and Identification. The marking and identification will be in accordance with
AMSE PALD Standards, paragraph 1. If the stand does not have these markings then it does not
meet US Army requirements and shall not be used.
(a) Rated Capacity. The rated capacity will be marked in a prominent location by casting imprint,
metal stamp, or use of durable materials and attachment methods.
(b) Identification. The original manufacturer or supplier will be marked in a prominent location by
casting imprint, metal stamp, or use of durable materials and attachment methods.
7. Testing Requirements.
Vehicle support stands are tested by
the manufacturer at
time of
production.
If a vehicle support stand has a U.S. Army data plate affixed, with a contract number stamped on the data
plate, the stand has already been tested and does not require subsequent testing. If there is no indication
of completed testing by the manufacturer, the stand must be tested prior to use. The using unit is
required to verify the proof load test of each vehicle support stand at 150% of rated capacity, and create a
Certificate of Conformance (COC) to record compliance of each individual vehicle support stand and keep
the certificate on file.
WARNING
Vehicle stands MUST be inspected for damage, defects or excessive
corrosion prior to every use. The use of damaged, corroded, or
otherwise defective stands could result in failure of the stand, causing
severe injury or death to the user.
a. The Operator and/or Unit level of maintenance will always inspect the stands for proper function
and safety prior to each instance of usage. Those stands that fail inspection must be identified
(affix DA Form 2402), segregated from other stands, and be disabled to preclude usage. The
defective stands will be disposed of in a timely manner in accordance with local disposal policies.
Replacement stands can be ordered through appropriate supply channels.
(1) The user will inspect the stand for the required legible markings.
(2) The base will be inspected for bends, separated welds, cracks, excessive corrosion,
damaged, loose or missing parts, or other evidence of mishandling or excessive wear. Any
evidence of these conditions will render the stand unsafe for use and require its replacement
with a stand that is known to be safe for use (see PMCS table, paragraph 9).
(3) The rack and pawl will be inspected for evidence of improper engagement or extreme wear.
The engagement areas will be free of dirt, debris, and excessive wear. A functional test
(manual operation to determine that all parts operate as required) of the rack and pawl
should be performed prior to use to insure the complete and proper engagement of
teeth. If
there is
any doubt concerning the reliability of
the stand, it
should be
replaced.
