21、oses of this European Standard the definitions of EN 50290-1-2 apply. 4 Test method 4.1 Sample A length of cable (typically 3 m in length). 4.2 Equipment The apparatus consists of : a) a shot-gun, as specified in the Detail Specification; NOTE 1 The type of gun is likely to vary from country to coun
22、try. b) a frame for holding the cable sample. It is important that the sample is free to move and the test set-up should also take into account that the shot may scatter in an elliptical manner depending on the gun used; c) gun shot : - size 4 or 7 or as specified in the Detail Specification ; NOTE
23、2 The shot size is likely to vary from country to country, and should represent the hazard particular to the installation. - the shot type shall be specified in the Detail Specification ; NOTE 3 Typically lead or steel is used, depending on the country. Lead shot deforms on impact and is less damagi
24、ng than steel shot. - the cartridge type shall be specified in the Detail Specification.1)At draft stage.- 5 - EN 50289-3-12:2001 4.3 Procedure The cable sample shall be mounted on the frame and shot at from the distance specified in the Detail Specification. A typical distance is 20 m. The number o
25、f shots with visible impact should be low, typically three or less, in order to give a reproducible test. If more than three shots hit the cable, then the test may be repeated if any of the requirements are not met. 4.4 Details to be specified The detail specification shall include : a) gun type, b)
26、 shot size, c) shot type, d) cartridge type, e) distance between gun and sample. 5 Requirements The acceptance criteria for the test shall be stated in the relevant Detail Specification. Typical failure modes include damage to the cable core elements and cable sheath (e.g. piercing of loose tubes) a
27、nd loss of continuity. 6 Test report The test report shall include: - temperature; - sample length; - details of test configuration, including cable orientation; - report of damage inflicted, including fibre and conductor continuity; - report of damages on sheath and screens; - number of tests carri
28、ed out, to achieve minimum visible impacts; - pass/fail criteria.BS EN 50289-3-12:2001 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for preparing British Standards.
