MIL-DTL-85052B
3.5.2.1 Clamp band hardness. Clamp band hardness shall be 51-59 hardness reading
(HR) Rockwell Superficial Scale, 30N, when tested in accordance with 4.3.3.
3.5.3 Clamp assembly performance.
3.5.3.1 Diametral retention. Each clamp sample as specified in 4.4.4.1 shall be tested in
accordance with the diametral retention test both before and after being subjected to the vibration
test (see 4.4.4.2.1). The clamp shall withstand an axial mandrel force as specified below:
Clamp Band Thickness
Axial Mandrel Force
0.020"
15-45 lbs
0.032"
25-55 lbs
0.040"
35-65 lbs
3.5.3.2 Vibration and transmissibility. The clamps shall not exhibit any evidence of
cushion separation or other deterioration when tested in accordance with 4.4.4.2. There shall be
no cracking or separation of metal components. The Transmissibility Ratio shall be recorded
(see 4.4.4.2.2).
3.5.3.3 Ozone resistance. When specified on the applicable specification sheet, the
clamps shall not exhibit any evidence of cracking on the outside circumference of the cushion
visible to the unaided eye when tested in accordance with 4.4.4.3. Cracks in cushion material
pinched between the metal band feet shall not cause the test to be considered a failure.
3.5.3.4 Thermal shock. The clamps shall not exhibit evidence of cracking, tackiness, or
degradation of the cushion material when tested in accordance with the thermal shock test
(see 4.4.4.4).
3.6 Surface texture. All surfaces shall have a smooth finish and shall be free from burrs
and sharp edges. The inside edges of the clamp band shall be rolled or provided with a radius to
eliminate sharp edges.
3.7 Identification of product.
3.7.1 Identification of clamps. Clamps shall be marked as specified on the applicable
specification sheet.
3.8 Workmanship. Workmanship shall be of a sufficiently high grade to ensure that
clamps are of uniform quality and free from burrs, slivers, sharp edges, or other defects, which
would affect their service and shall be uniform in appearance without any mold flash.
