# §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](/cfr/33/183.5.md)).
- (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](/cfr/33/183.5.md)).
- (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](/cfr/33/183.5.md)).
- (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](/cfr/33/183.5.md)).
- (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)](#a..g) of this section is measured in accordance with ASTM D 2842 (incorporated by reference, see [§ 183.5](/cfr/33/183.5.md)).
