Whistle for lifejackets, approved according to EN ISO 12402-8*. Please note to meet this standard whistles must be non metallic, loud (100dBA at 5 metres), able to be attached securely to a lanyard, be tough, and generate a two tone sound i.e. have at least two different frequencies to help avoid sound absorption. This whistle is all of these things and more (but not much more) Features Moulded clip for pocket or pouch Patented jam/lock design for secure cord attachment. The perfect, trouble-free, no-maintenance survival tool for paddling or camping or to carry (on a key ring maybe). This whistle takes less effort and energy to produce a louder, penetrating audible sound than can ever be achieved vocally. Because it is pealess, the safety whistle will always work- No pea to jam especially when filled with water.. Plastic for weight, corrosion resistance and comfort in cold weather (and to avoid sticking to your lips in freezing conditions) From EN ISO 12402-8 5.2.1 Whistles shall be non‑metallic and robust in construction, free from all burrs, and shall not rely on any moving part for the production of sound. 5.2.2 Three specimens shall be tested by being blown as hard as possible by a subject of between 20 years and 30 years of age and free from all known impairments to pulmonary function, in an outside and open area during calm clear weather. The sound generated shall be shown at least at an instant to have exceeded 100 dB(A) measured at a distance of (5 ± 0,1) m directly in front of the whistle. The predominant frequency shall be (2 ± 1) kHz and shall be multi‑tone. NOTE Multi‑tone means that the whistle has two chambers which emit different primary frequencies. 5.2.3 The whistle shall also be shown to be capable of producing sound in air immediately following immersion in fresh water. The procedure in 5.2.2 shall be repeated immediately after the whistle has been removed from immersion in fresh water. 5.2.4 The whistle shall be attached to a cord or line of a length sufficient to permit its use, which shall in turn be attached securely to the lifejacket or buoyancy aid. The attachment and the cord of the whistle shall be loaded vertically with a static load of (200 ± 10) N for 60 s without any damage or separation of the whistle from the PFD. 5.2.5 The whistle shall be stowed on the device in such a way that the performance of the lifejacket is not affected, but so that it can be removed for use with either hand of the user, and can be stowed by the user. The stowage of the whistle shall be verified when the lifejacket is tested according to
