4.1.3 Resistance to cleaning, disinfection and decontamination The suit, complete with all attachments and samples of suit materials and each suit material combination, shall be subjected to cleaning, disinfection and, where applicable, to decontamination, in accordance with 5.4.1.3 and shall then be visually inspected in accordance with 5.3. There shall be no visible signs of damage or degradation. 4.1.4 Resistance to repeated pressurization in water When tested in accordance with 5.4.2, the thermal insulating material used in the construction of the suit shall not loose more than 5 % of its original thickness. 4.1.5 Tensile strength of material When samples of thermal insulating material that have been subjected to testing in accordance with 5.4.2 are tested in accordance with 5.4.4 the material shall withstand a tensile load of 150 N for 10 s without breaking. 4.1.6 Resistance to permanent deformation After the testing for tensile strength (5.4.4), the permanent elongation of the suit material, when measured in accordance with 5.4.7, shall be less than 5 % of the original length. 4.1.7 Strength of suit seams When tested in accordance with 5.4.5, each type of seam used to manufacture the suit shall withstand a tensile load of 100 N for 10 s without breaking. 4.1.8 Strength of closures When tested in accordance with 5.4.6, each type of closure (including touch and close fasteners and slide fasteners) shall withstand a tensile load of 100 N for 10 s without opening. 4.2 Limitation of water flow into and out of the suit 4.2.1 Seams All seams between thermal insulating material components of the suit shall be provided with means (e.g. glue, weld, tape) to prevent free flow of water through the seam when tested in accordance with 5.3 and 5.4.5. 4.2.2 Closures All closures, including touch and close fasteners and slide fasteners shall be provided with means of reducing the free flow of water through the closure, for example a flap that can be secured over the closure when tested in accordance with 5.3. 4.3 Thermal performance of suit materials The thermal insulating material used for the construction (see 4.1.4) of the suit shall be of one of the thermal performance classes specified in Table 1 when tested in accordance with 5.4.3.

This will be allowed only as a seal or for comfort purpose. 4.4 Sizing The manufacturer shall use the sizing system specified in EN 340 or another sizing system. If the manufacturer uses a sizing system other than that specified in EN 340, the manufacturer shall state at least two body dimensions including at least the height and chest girth of the intended user. When the suit is donned by a test diver in accordance with 5.5.6.2 the size of the suit shall correspond to the size marked on it by the manufacturer. 4.5 Practical performance When tested in accordance with 5.5.6.2 it shall be possible for the suit to be donned and doffed with the assistance of no more than one person. When wet suits are subjected to practical performance tests in accordance with 5.5 the test divers shall be able to carry out all the procedures listed in 5.5.6.2 and 5.5.6.3 and not report a practical performance score of 5 or more (given in Annex B) for more than 3 of the separate test procedures and no score higher than 8 for any procedure. When tested in accordance with 5.5.6.2 the satisfactory surface condition of the suit in contact with the user shall be confirmed by showing no excessive irritation, abrasions or other skin injuries.
5 Test methods 5.1 General Samples of the material used in the manufacture of the wet suit, where applicable assembled in the same way as in the suit (e.g. in the case of seams), and at least three wet suits, including one of each size if applicable, shall be submitted for visual inspection (see 5.3) and testing. One suit shall undergo laboratory tests in accordance with 5.4.1.1, 5.4.1.2 and 5.4.1.3, the samples of material shall undergo laboratory tests in accordance with 5.4 and all three suits shall undergo practical performance tests under realistic conditions in accordance with 5.5.

0,1 m2. The tank in which the apparatus is immersed shall be at a uniform temperature between 10 °C and 15 °C and the difference between the water temperature within the apparatus and the external water temperature shall be between 25 °C and 30 °C. Each sample shall be tested at pressures of 1 bar absolute and 6 bar absolute.
