4 Tests
4.1 Visual inspection
Visual inspection shall be conducted at normal visual acuity.
The visual inspection shall include tactual examination and the assessment of the device marking, information supplied by the manufacturer and any safety data sheet.
4.2 Heel band test
4.2.1 Resistance to slipping
The fins shall be suspended on a support body having a radius of 20 mm by means of the heel band.
Each heel band adjustment shall be set to its midpoint.
A tensile force of 150 N is applied to the open.heel fin in the direction of the heel, for duration of lOs.
4.2.2 Resistance to slipping out or detachment
The fins shall be suspended on a support body having a radius of 20 mm by means of the heel band.
Each heel band adjustment shall be set to its midpoint.
A tensile force of 200 N is applied to the open-heel fin in the direction of the heel, for duration of 10 s.
4.2.3 Permanent linear deformation
Test three samples: one end of the band is fixed; apply the force of 100 N to the free end of the heel strap for 10 s.
Measure the permanent linear deformation 30 mm after the pull test.
4.3 Practical performance
During the test the fins will be subjectively assessed by three test subjects and their comments on the following points shall be recorded after the test:
— donning and doffing of the fins as well as adjustment of all straps (if applicable), without help on land;
— jumping into water (feet first) from the height of 1.5 m;
— swimming at a depth of at least I m for 15 m.
During jumping and swimming the fin shall not be damaged and shall not detach or become loose.
5 Marking
Each fin shall be marked according to the relevant following items:
a) the manufacturer shall be identified by name, trade mark or other means of identification;
b) size (if applicable);
c) type-identifying mark;
d) the number of this European standard.BS EN 16804 pdf download.
