DIN EN 1972:2016-02 EN 1972:2015 (E) 4 Introduction A snorkel allows the user to breathe, when swimming in a prone position, without having
24、 to raise the mouth out of the water. DIN EN 1972:2016-02 EN 1972:2015 (E) 5 1 Scope This European Standard specifies safety requirements in order to increase the safety in the use of snorkels for swimmers and divers. This European Standard is applicable to snorkels, which allow users to breathe at
25、the water surface whilst floating with the face submerged. It covers snorkels used by swimmers and divers. This European Standard is not applicable to combined face masks and snorkels, in which the snorkel tube opens into face mask. 2 Terms and definitions For the purposes of this document, the foll
26、owing terms and definitions apply. 2.1 snorkel device composed of a hose and/or tube with a mouthpiece, allowing a user to breathe while swimming in a prone position; it may also include optional devices such as valves and water deflectors 2.2 mouthpiece part of the snorkel, usually held by the teet
27、h, sealing against the lips and through which air is inhaled and exhaled 3 Requirements 3.1 General The snorkel shall not have any projecting parts, or corners and edges, which can cause injury. Test in accordance with 4.1 and 4.5. 3.2 Dimensions The dimensions of a snorkel shall comply with Table 1
28、. Table 1 Dimensions Class Application Total inner volumeaml max. Lbmm max. A people with large lung capacities 230 380 B people with small lung capacity (e.g. children) 150 350 aThe total inner volume representing the dead space of the snorkel for respiratory exchange. bLinear distance between the
29、centre of the mouthpiece opening and the lowest part of the air intake opening. Test in accordance with 4.1 and 4.2. DIN EN 1972:2016-02 EN 1972:2015 (E) 6 3.3 Mouthpiece The mouthpiece material shall not be known to be likely to cause irritation or any other adverse effects to health. The mouthpiec
30、e shall be designed so that is easily retained in the mouth, e.g. using lug(s) for gripping between the teeth. All parts of the mouthpiece coming in contact with the oral mucosa shall be smoothly finished. The end of the tube shall not extend beyond the mouthpiece into the mouth. Test in accordance
31、with 4.1 and 4.5. 3.4 Resistance to air flow When tested in accordance with 4.3, the peak respiratory pressure of the snorkel during inhalation and exhalation shall be within the range of 10 mbar. 3.5 Joints When tested in accordance with 4.4 with an axial force of 30 N for 10 s, joints shall show n
32、o signs of disengagement. 3.6 Optional devices 3.6.1 Snorkel keeping device Any snorkel keeping device affixed to the tube to prevent loss of the snorkel in use, shall be arranged in such a way that the position of the snorkel can be adjusted. The snorkel keeping device shall enable the snorkel to b
33、e displaced from the mouth and replaced without having to displace the face mask. Test in accordance with 4.1 and 4.5. 3.6.2 Shut-off valves If a shut-off valve to prevent the ingress of water is fitted, it shall only shut off when submerged. After being submerged the valve shall easily open on the
34、first exhalation. Test in accordance with 4.5. 4 Test methods 4.1 Visual inspection Visual inspection shall be conducted at normal visual acuity. The visual inspection shall include the assessment of the device marking, information supplied by the manufacturer and any safety data sheet. 4.2 Testing
35、of dimensions The inner volume of the snorkel may be determined either by dimensional measurement and calculation or by filling the snorkel with water. Put the snorkel with its mouthpiece in a position that it would be during normal use. DINEN 1972:2016-02EN 1972:2015 (E) 7 Determine the linear dist
36、ance L between the centre of the mouthpiece opening and the lowest part of the air intake opening. 4.3 Resistance to air flow test Connect the mouthpiece to a breathing simulator. Set the breathing simulator to a sinusoidal operation of 25 strokes/min with 2,5 l/stroke at ambient pressure and temper
37、ature. The deviation between frequency and amplitude shall not be more than 3 %. Take the pressure recording at the mouthpiece. Continue the measurement until steady-state is achieved. 4.4 Joint strength test A tensile testing machine or a dead weight arrangement with means for measuring with accura
38、cy of 2 N over the whole measuring range shall be used. Apply a load of (30 2) N across the joint at a uniform rate over 5 s. Maintain the force for 10 s and examine the joint for any damage. 4.5 Practical performance test 4.5.1 General For reasons of safety, practical performance tests should be ca
39、rried out only after all laboratory tests, according to 4.1 to 4.4, have been satisfactorily completed. 4.5.2 Test subjects The snorkel shall be tested by subjects who are practicing regularly with snorkels. 4.5.3 Basic testing Each test subject shall make a test swim which include at least two subm
40、ersions to a depth of at least 1 m. During the test the snorkel will be subjectively assessed by the user and the users comments on the following points shall be recorded after the test: a) snorkel comfort; b) security of any joints and attachments; c) adjustment of the mouthpiece and any snorkel ke
41、eping device; d) ease of breathing and of opening of any shut-off valve on the first exhalation; e) any other comments reported by the user on request. 4.5.4 Report A record with a final report of the tests performed with the test persons shall be kept. DIN EN 1972:2016-02 EN 1972:2015 (E) 8 5 Marki
