Subpart F—Flotation Requirements
for Inboard Boats, Inboard/Outdrive Boats, and Airboats
Sec. 183.114—Test of flotation materials
(a) Vapor test. The flotation material must
not reduce in buoyant force more than 5 percent after being
immersed in a fully saturated gasoline vapor atmosphere for
30 days at a minimum temperature of 38 deg. C.
(b) 24-hour gasoline test. The flotation material
must not reduce in buoyant force more than 5 percent after
being immersed for 24 hours at 23 plus or minus 2 deg. C in
reference fuel B, of ASTM D 471 (incorporated by reference,
see Sec. 183.5).
(c) 30-day gasoline test. The flotation material
must not reduce in buoyant force more than 5 percent after
being immersed for 30 days at 23 plus or minus 2 deg. C in
reference fuel B, of ASTM D 471 (incorporated by reference,
see Sec. 183.5).
(d) 24-hour oil test. The flotation material
must not reduce in buoyant force more than 5 percent after
being immersed for 24 hours at 23 plus or minus 2 deg. C in
reference oil No. 2, of ASTM D 471 (incorporated by reference,
see Sec. 183.5).
(e) 30-day oil test. The flotation material
must not reduce in buoyant force more than 5 percent after
being immersed for 30 days at 23 plus or minus 2 deg. C in
reference oil No. 2, of ASTM D 471 (incorporated by reference,
see Sec. 183.5).
(f) 24-hour bilge cleaner test. The flotation
material must not reduce in buoyant force more than 5 percent
after being immersed for 24 hours at 23 plus or minus 2 deg.
C in a 5-percent solution of trisodium phosphate in water.
(g) 30-day bilge cleaner test. The flotation
material must not reduce in buoyant force more than 5 percent
after being immersed for 30 days at 23 plus or minus 2 deg.
C in a 5-percent solution of trisodium phosphate in water.
(h) The buoyant force reduction in paragraphs
(a) through (g) of this section is measured in accordance
with ASTM D 2842 (incorporated by reference, see Sec. 183.5).
