23、the ability of a passive fibre optic device or a closure to withstand impacts likely to be encountered during usage. The impact may be a localized impact, a series of impacts with hard objects, or an impact normally associated with dropping the device. 2 Normative references The following referenced

Method B: a steel ball is droppe
27、d on the specimen which is placed on a smooth hard rigid surface of concrete or steel. Method C: the specimen is released such as to allow free fall drops from the position of suspension. Impairment of function to the extent that the device fails to meet the requirements of the relevant specificatio
28、n constitutes failure. 4 Apparatus 4.1 Method A Pendulum drop 4.1.1 Attaching fixture The attaching fixture shall be capable of being mounted on any convenient, rigid, vertical structure. If the device has an attached cable, the cable shall be mounted to the fixture in such a manner as to allow it t
29、o swing freely from a horizontal to a vertical position. An BS EN 61300-2-12:2009EN 61300-2-12:2009 (E) 6 example of a suitable set-up is shown in Figure 1. For devices which have no cable attached, one of two options shall be used: a) a connector assembly adaptor or other fixture of equivalent or l
30、ess weight shall be mounted such that a patchcord cable can be attached, or b) method C shall be used. 4.1.2 Surface plate The impact surface shall be a steel plate with a minimum thickness of 12,5 mm. The surface area of the plate shall be commensurate with the specimen dimensions. 4.2 Method B Imp
31、act with steel ball 4.2.1 Impact tool A steel ball of 1 kg shall be dropped from a hand-held position, or by a release device. Where necessary, other masses and shapes of the impact tool may be defined in the relevant specification. 4.2.2 Surface Unless otherwise specified, all test specimens shall
32、be positioned on a smooth hard rigid surface of concrete or steel. Where necessary, other surfaces may be defined in the relevant specification. 4.2.3 Drop apparatus An example of an apparatus to drop the impact tool is given in Figure 2. It consists of a hollow tube (guide) with a release system. T
33、he inner diameter of the tube shall be wide and smooth enough to minimise interaction between the tube and impact tool during the free fall. h l Attaching fixture Impact surface Specimen IEC 1169/11 Values for the cable length l and the drop height h are given in 5.4.2.

Where a liftingrelease device is used for the test, it shall not imp
35、art a rotational or sideways force to the specimen. 4.3.2 Impact surface Unless otherwise specified, all drops shall be on to a smooth hard rigid surface of concrete or steel. Where necessary, other surfaces may be defined in the relevant specification. 5 Procedure 5.1 Preparation of specimen Prepar

Visual examination shall be done according to IEC 61300-3-1
38、. 5.4 Test method 5.4.1 General One of the following three methods shall be used in this test. They require examinations and measurements before and after the test only. If examinations and measurements are required during the test by the relevant specification, details will be specified in the rele
39、vant specification. 5.4.2 Method A 5.4.2.1 Drop height Attach the cable clamping fixture at a drop height h from the impact surface as shown. The height, h, shall be 1,5 m. 5.4.2.2 Cable lenght The cable length, l, shall be 2 m. 5.4.2.3 Fixation Hold the specimen in a horizontal position with the ca
40、ble fully extended as shown and allow it to drop on to the impact surface. 5.4.2.4 Cycle Repeat the cycle 5 times. 5.4.3 Method B 5.4.3.1 Impact tool A steel ball with mass 1 kg shall be positioned above the centre of the specimen, using the equipment as described in 4.2.3 at an appropriate drop hei
41、ght, h, which shall be measured from the part of the specimen nearest the impact surface, shall be selected from Table 1. Table 1 Drop height IEC 61753-1 performance category Drop height h m Category A (Aerial) and G (Ground) 1 Category S (Subterranean) 2 5.4.3.2 Position Specimen shall be positione
42、d in an orientation such that it will be subjected to impact in the centre of the specimen. The specimen shall be subjected to one impact in this position. 5.4.3.3 Cycle Repeat the cycle for other impact locations by rotating the specimen along its longitudinal axis by 90. In total 4 positions shall
43、 be tested (at 0, 90, 180 and 270).

44、ubjected to impact on its resting surface, a corner or an edge as described in 5.4.4.2. 5.4.4.2 Drop height The drop height h, which shall be measured from the part of the specimen nearest the test surface, shall be determined from Table 2. Table 2 Drop height and specimen mass Specimen mass kg Drop
45、 height h mm 0 to 50 25 5.4.4.3 Corner and edge drop For corner or edge drops, the specimen shall be positioned such that a straight line drawn through the corner or edge to be tested and the specimens geometric centre is approximately perpendicular to the impact surface as shown in Figure 3.

47、wo corners and two edges. 5.4.5 Severity 5.4.5.1 Method A Method A has one level of severity: 5 drops from 1,5 m. 5.4.5.2 Method B Method B has two levels of severities: impact with steel ball of 1 kg from 1 m or 2 m. 5.4.5.3 Method C The severity consists of a combination of the drop height and the
48、 number of impacts. 5.5 Recovery Since examinations and measurements are to be made at the test conditions, no minimum recovery time is required. Clean the specimen in accordance with the manufacturers instructions. 5.6 Final examinations and measurements On completion of the test, remove all fixtur
49、es and make final examinations and measurements, as defined by the relevant specification, to ensure that there is no permanent damage to the specimen.
