22、t methods for diving masks to protect the eyes of persons engaged in underwater activities where the user is breathing underwater. Full face and oro-nasal masks are not covered by this European Standard. 2 Terms and definitions For the purposes of this document, the following terms and definitions a
23、pply. 2.1 diving mask mask that seals on the face, that only covers the eyes and nose in a single volume 2.2 lens transparent part(s) of the mask which enables the user to see underwater Note 1 to entry: A diving mask can have more than one lens. 2.3 head strap device used to maintain the diving mas

25、e 1 to entry: The lens seal may also be part of the face seal. 3 Safety requirements 3.1 Design The mask shall not have any projecting parts, or corners and edges, which can injure the user. The mask shall be provided with means to allow the occlusion of the nasal passages, to aid ear clearing. All
26、parts which have to be actuated by the user underwater shall be accessible and operable even when wearing protective gloves. (Three finger gloves 206+mm thickness, doubled lined). These parts shall be designed such that the setting cannot be altered inadvertently during use. DIN EN 16805:2016-02 EN
27、16805:2015 (E) 5 Materials, including any anti-fogging compound specified by the manufacturer, that may come into contact with the wearers skin shall not be known to be likely to cause irritation or any other adverse effects to health. Testing shall be done in accordance with 4.2 and 4.6. 3.2 Lens 3
28、.2.1 General a) Any (main/front) lens shall not distort vision; Testing shall be done in accordance with 4.2 and 4.6. b) Lens shall be attached in a reliable and tight manner to the mask; Testing shall be done in accordance with 4.2, 4.5 and 4.6. c) Where anti-fogging compounds are used as intended
29、or specified by the manufacturer, they shall be compatible to eyes, skin, nasal mucosa and to the components of the diving mask. Testing shall be done in accordance with 4.2. 3.2.2 Impact resistance The lens shall be resistant against impacts. Testing shall be done in accordance with 4.3.1. 3.2.3 Br
30、eak pattern When tested for break pattern in accordance with 4.3.2, either: the lens specimen remains intact; or no individual fragment shall weigh more than 3,6 g, and measure more than 25 mm. Testing shall be done in accordance with 4.3.2. 3.2.4 Lens seal Lens seal of the diving mask should provid
31、e a good seal against the lenses. Testing shall be done in accordance with 4.5. 3.3 Head strap and attachment Head strap and attachment shall be designed so that the diving mask can be donned and removed easily. When wetted, the head strap(s) and attachment of a diving mask shall withstand a pull fo
32、rce of 40 N, during 10 s, without slipping, and a pull force of 100 N, during 10 s, without detaching or slipping out of the attachment and/or buckles. Testing shall be done in accordance with 4.4.1. The permanent linear deformation of the head strap(s) shall not be greater than 5 % when tested at a
33、 pull force of 30 N for 10 s, measurement being carried out 30 min after pulling. Testing shall be done in accordance with 4.4.2. DIN EN 16805:2016-02 EN 16805:2015 (E) 6 3.4 Face seal Face seal of the diving mask should provide a good seal on the face. All parts of the face seal coming into contact
34、 with the face shall be smoothly finished. Testing shall be done in accordance with 4.2 and 4.6. 4 Test methods 4.1 General Unless otherwise specified, the values stated in this standard are expressed as nominal values. Unless otherwise specified, values shall be subject to a tolerance of 5 %. Unles
35、s otherwise specified, the room temperature for testing shall be (24 8) C and at a relative humidity of at least 50 %. The temperature limits with no specified tolerance shall be subject to an accuracy of 3 C. 4.2 Visual inspection Visual inspection shall be conducted at normal visual acuity. The vi
36、sual inspection shall include tactual examination and the assessment of the device marking, information supplied by the manufacturer and any safety data sheet. 4.3 Lens 4.3.1 Impact resistance Impact resistance shall be tested using a completely assembled diving mask mounted on a rigid support such
37、that a steel ball (25,4 mm diameter, 66 g) falls normally from a height of 130 cm onto the lens. If the mask provides a separate lens for each eye or a single lens covering both eyes of a regular shape (e.g. round, oval, rectangular), the steel ball shall hit the geometric centre of the lens within
38、a 25 mm diameter. If a single lens covers both eyes and is of an irregular shape (e.g. with a nose indent), two separate tests shall be conducted where the steel ball hit a modified geometric centre over each eye within a 25 mm diameter. The lens shall not break. 4.3.2 Break pattern Same procedure a
39、s 4.3.1, but the height from which the ball is dropped shall be as follow: starting at 3 m, that height shall increase by 50 cm increments up to 5 m and then at a maximum of 5,3 m. The height shall be increased until the lens breaks or the maximum height is reached. Lens tested shall be enclosed in
40、a polyethylene bag to facilitate fragment identification (the thickness of the polyethylene bag covering the lens shall not exceed 0,075 mm). Interpretation of results: the test for break pattern shall be judged to have satisfactorily completed if one of the following criteria are met: the lens spec
41、imen remains intact after an impact from the 3,005 m ball drop; the break pattern shall exhibit a spalled surface of innumerable small pieces, which may be described as granular, across and through the entire lens area. The lens shall be inspected 3 min after the impact. Any fragment, free of any cr
42、ack, shall be measured and weighted. DIN EN 16805:2016-02 EN 16805:2015 (E) 7 4.4 Head strap 4.4.1 Resistance to slipping The diving mask shall be fixed on a support as shown in Figure 1. Each head strap adjustment shall be set to its mid-point. The pull force shall be applied as shown in Figure 1.

DIN EN 16805:2016-02 EN 16805:2015 (E) 8 Key F force Figure 2 Test configuration for permanent linear deformation 4.5 Water tightness test a) Support the dry mask horizontally, face downwards,
45、above a clean sheet of dry absorbent paper so that the supports are clear of the seal between the lens and the mask. Pour sufficient water into the mask cavity to give a depth of 20 mm or the maximum that can be achieved above the lens whichever is the lower. Examine the absorbent paper and the oute
46、r side of the lens after 30 min, no water shall be detectable. b) Place the dry mask horizontally, face downwards, in an empty bowl and arrange it so that water has free access to the lower side of the lens, and its inner face is weighted so as to give the mask negative buoyancy in water. Pour water
47、 into the bowl to a depth of at least 20 mm or the maximum that can be achieved above the lens whichever is the lower. Examine the inside of the mask after 30 min, no water shall be detectable. All testing will be carried out on three samples of diving mask. DIN EN 16805:2016-02 EN 16805:2015 (E) 9
48、4.6 Practical performance 4.6.1 General For reasons of safety, practical performance tests should be carried out only after all laboratory tests have been satisfactorily completed. 4.6.2 Test subjects The diving mask shall be tested by three test subjects who are able to achieve a good face seal wit
49、h the mask under test, they should not have any facial hair and should be practicing regularly with diving masks. 4.6.3 Basic testing Each test subject shall make a test dive to a depth of at least 3 m while wearing protective gloves. During the test the diving mask will be subjectively assessed by three test subjects and their comments on the following points shall be recorded after the test: a) mask comfort; b) security of mask and head strap(s); c) adjust
