EN 14225-2:2005 (E) 4 Introduction This document for dry diving suits has been prepared to meet the needs of persons engaged in underwater activities where the user is breathing underwater, and where thermal comfort and required thermal protection is higher than that provided by a wet suit. A dry suit is also designed to enable the wearers to maintain their buoyancy and to adjust the gas volume in the suit according to their requirements. A dry suit may be comprised of one or more pieces. Dry suits may be used in conjunction with a range of accessories including passive and active undergarments, gloves, a hood and other head protection equipment. The conformity of a dry suit to this document does not imply that it is suitable for all circumstances, nor does the standard make detailed provisions for all the special uses for which dry suits may be utilised. A dry suit manufactured for special purposes may also: a) provide or enable thermal insulation; b) provide special protection. The level of protection and performance offered by a dry suit may be altered by a number of factors, including the water temperature, the depth of the dive, the diver’s work rate and behaviour, and the manner in which the suit has been maintained. The adequacy of the protection provided by a dry suit also depends upon the individual diver’s level of cold tolerance. The degree of thermal protection offered by a dry suit is especially problematic. Appropriate material and manikin tests are being developed and refined, but at best they will only be able to provide broad indications of the likely protection provided by a particular suit to an individual diver.

This enhanced visibility shall be for the relevant use environment. The colour fastness (dry and wet) of suit material when determined in accordance with ISO 105-A02:1993 shall be resistant to rubbing (wet and dry), when tested in accordance with EN ISO 105-X12:2002 to at least step 4, and to salt water when tested in accordance with EN ISO 105-E02:1996 to at least step 4. 4.6.3.2 Retroreflective material There shall be affixed to the suit surface a total area of at least 400 cm2 of material, which is retroreflective to light and which conforms to the requirements detailed in SOLAS:1974, as amended, Chapter III as amended by IMO Resolution MSC 47(66) and LSA Code, adopted by Res. A.658(16), Annex 2, issued by
the International Maritime Organisation (IMO). These retroreflective areas shall be located in at least two positions of the suit. Preference shall be given to the upper body, and parts of the suit that will not be covered by attachment or by other parts of the diving equipment. When retroreflective material attached to a suit, and the same material that has not been attached to a suit are tested in accordance with EN ISO 15027-3:2002, 3.11.6.4.2, there shall be no difference in retroreflectivity between the two samples. 5 Test methods 5.1 General At least three dry suits of different sizes including the largest and the smallest sizes, as stated by the manufacturer, together with material samples shall be submitted for visual inspection (see 5.3) and testing. One suit and suit material samples where appropriate shall undergo laboratory tests in accordance with 5.4 and 5.5, and all three suits shall undergo leakage test (5.5.2) and practical performance tests under realistic conditions in accordance with 5.6. 5.2 Test sequence The tests shall be conducted in accordance with the flow chart shown in Figure 1.
