Testing of protective canvas
NOTE The possibility to use canvas tested according to ISO standards will be considered when a revision is undertaken
Five horizontal and five vertical samples, each 50 mm wide, were extracted from protective canvas These samples underwent tensile testing in a machine, where a 250 mm length was subjected to a tractive force that increased at a rate of 11 N per second.
Test results are considered to be acceptable when the average tearing resistance for horizontal and vertical samples is 3 000 N or more
Five circular samples of protective canvas were tested by placing each into a device with a free testing zone of 100 mm in diameter An increasing load of 11 N per second was applied to each sample using a punch with a 10 mm x 10 mm cross-section and a chamfer of 1 mm x 45°.
Test results are deemed acceptable when the average perforation force is at least 1,000 N and the average perforation energy is no less than 8 Nm.
A 200 mm wide sample is extracted from the full height of the protective canvas and placed on an abrasive machine The free end of the sample, covering a surface area of 400 cm², rests on a 200 mm wide abrasive wheel with a diameter of 800 mm The wheel is equipped with a 24 grain size abrasive belt, operating at a speed of 25 min\(^{-1}\).
The 400 cm² surface will bear a load of 5 N To ensure uniform pressure distribution, the pressure pad must conform to the wheel's shape and be covered with a 30 mm thick layer of polystyrene with a specific density.
Test results are considered to be acceptable when:
on an armoured canvas, reinforcement fibres are not worn through after 10 000 rotations;
on a non-armoured canvas, thickness is still at least half that of the original thickness after 10 000 rotations
