6、 intended for United States Coast Guard (USCG)approval under 46 CFR 160.077 as recreational use devices.2 Units of Measurement2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.3 Undated References3.1 Any undated reference to a

7、code or standard appearing in the requirements of this standard shall beinterpreted as referring to the latest edition of that code or standard.4 Glossary4.1 For the purpose of this standard the following definitions apply.4.2 AUTOMATIC INFLATION SYSTEM A system that automatically inflates one or mo

8、recompartments when the buoyant device is submerged in the water, and operates independently of anyaction by the wearer.4.3 BELT A device that wraps around the torso but does not cover the shoulders or arms in thedeflated condition.4.4 CLOSURESa) Primary A means of securing the device onto the body

9、so that the device can be expectedto function substantially in the intended manner without the use of any other means of fasteningthe device onto the body.b) Secondary A closure that:1) If it is the only closure that is closed on the device, does not result in the devicebeing donned as intended; and

10、2) Is not usually required to be closed in order for the device to substantially complywith the requirements in this standard.4.5 DESIGN PRESSURE RANGE The range of pressures, as specified by the manufacturer, towhich a compartment may be inflated to provide the intended in-water performance.JANUARY

23、5th through 95th percentileof the adult U. S. population with respect to height and girth.4.25 VEST A device that covers the shoulders but has no sleeves. A yoke-style device is consideredto be a vest.5 Components and Materials5.1 A component of a device covered by this standard shall (see Table 5.1
