20、tates Coast Guard (USCG). 1.2 The buoyant cushions covered by these requirements are intended for USCG approval under 46 CFR 160.048 or 160.049. 1.3 These requirements do not cover buoyant cushions that employ entrapped air as the prime buoyant means. 2 Units of Measurement 2.1 Values stated without

21、 parentheses are the requirement. Values in parentheses are explanatory or approximate information. 3 Undated References 3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 4
