(Specification)Standard Safety Specification for Consumer Trampoline Enclosures
Standard Safety Specification for Consumer Trampoline Enclosures
SCOPE
1.1 This safety specification covers the components, assembly, use, labeling, and performance requirements of consumer trampoline enclosures (see Specification F 381).
1.2 This specification is applicable to trampoline enclosures to be sold as an accessory to or packaged with trampolines of (1) a minimum bed size of 3300 in. (2.1 m2), 2 a minimum height of 20 in. (510 mm), (3) intended for the purpose of continuous, vertical jumping activities, and (4) intended for consumer use.
1.3 This specification includes the following sections and selected subsections:
SectionScope1Referenced Documents2Terminology3Components4General Requirements5Performance Requirements6Performance Tests6Information Packet7Product Marking8Packaging and Package Marking9
1.4 This standard does not purport to address all of the hazards that my be associated with trampolines or trampoline enclosures, or both. The standard's existence alone will not necessarily prevent injuries. Like other physical activities, trampoline use involves the risk of injury, particularly if the equipment is used improperly. Similarly, the use of a trampoline enclosure alone will not necessarily prevent all injuries.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 The following precautionary caveat pertains only to the test methods portion of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use..
