Code of Federal Regulations Title 33. Navigation and Navigable Waters § 33.183.114 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° 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° C in reference fuel B, of ASTM D 471 (incorporated by reference, see § 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° C in reference fuel B, of ASTM D 471 (incorporated by reference, see § 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° C in reference oil No. 2, of ASTM D 471 (incorporated by reference, see § 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° C in reference oil No. 2, of ASTM D 471 (incorporated by reference, see § 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° 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° 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 § 183.5).
