When tested in accordance with Appendix B, the attachment assembly shall not-
(a) show evidence of detachment from the flotation aid;
(b) show evidence of webbing or tapes slipping more than 25 mm past or through a fastening device (e.g. buckle, snap-lock fitting and similar); or
(c) fail or unfasten so that the test weight is released.
The ability of the flotation aid to withstand exposure to heat shall be such that when tested in accordance with Appendix A, it shall not suffer a loss of buoyancy greater than 10% of its initial buoyancy after being subjected to a temperature of 60 +2°C for 4h. For the purpose of this requirement, flotation aids which employ inflatable chambers as a source of buoyancy shall have those chambers inflated to a pressure of 6.9 +0.5, -0kPa at normal room temperature prior to exposure to heat.
Fasteners, excluding zip fasteners, that are fundamental to the operation of the flotation aid with respect to maintaining the flotation of the user shall meet at least one of the following:
(a) At least two simultaneous or sequential actions shall be required for their release or opening in order to prevent unintended opening. See Figure 3.1.
(b) Centre release fasteners that are able to be released or opened by one single action and are dependent on pressure for release shall require a force of more than 50 N applied to the release mechanism of the fastener in order for it to be released or opened. Testing shall be in accordance with Appendix D. See Figure 3.2(b).
(c) Side release fasteners that are able to be released or opened by one single action and are dependent on pressure for release shall require a force of more than 30 N applied to the release mechanism of the fastener in order for it to be released or opened.Testing shall be in accordance with Appendix D.
