2、2-2:2004 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 7 October 2004 BSI 7 October 2004 ISBN 0 580 44553 4 National foreword This Draft for Development is the official English language version of CLC/TS 50131-2-2:2004. This publication is
3、not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because it is a provisional European draft. It should be applied on this provisional basis, so that information and experience of its practical application
4、may be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion to a European Standard. A review of this publication will be initiated 2 years after its publication by the Eur
5、opean organization so that a decision can be taken on its status at the end of its 3-year life. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsi
6、ble BSI Committee will decide whether to support the conversion into a European Standard, to extent the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Subcommittee GW/1/1, Alarm components, at 389 Chiswick High Road, London W4 4AL, g
7、iving the document reference and clause number and proposing, where possible, an appropriate revision of the text.

28、ded by the manufacturer. All the test parameters specified shall carry a general tolerance of 10 % unless otherwise stated. A list of tests appears as a general test matrix in Annex B. 6.1 General test conditions 6.1.1 Standard laboratory conditions for testing The general atmospheric conditions in
29、the measurement and tests laboratory shall be those specified in EN 60068-1, sublause 5.3.1, unless stated otherwise. Temperature: 15 C to 35 C Relative humidity: 25 % RH to 75 % RH Air pressure: 86 kPa to 106 kPa 6.1.2 General detection testing environment and procedures Manufacturers documented in
30、structions regarding mounting and operation shall be read and applied to all tests. 6.1.2.1 Testing environment The detection tests require an enclosed, unobstructed and draught-free area at least 25 % larger in the three dimensions than the manufacturers claimed field of view, with the detector mou
31、nted in the as-used position on a wall or ceiling, or on a free-standing test rig. To standardize the test area walls and floor for IR tests, they shall each be covered with uniform materials having an infrared emissivity of at least 80 % in the 8 m to 14 m wavelength band, at least directly behind
32、the SWT, and in the FOV of the detector. Volumetric, curtain, and long-range detectors shall be mounted on the centre line of the vertical surface constituting the back wall of the test area, or on a free-standing test rig, at a height of 2,0 m unless otherwise specified by the manufacturer. Ceiling
33、 mounted detectors shall be mounted in an appropriate orientation permitting at least half the field of view to be verified. Annex C provides example diagrams for the range of walk tests for one format of detection pattern. Many others are possible. 6.1.2.2 Testing procedures The detector shall be c
34、onnected to the nominal supply voltage, placed in the alert/set mode, and connected to the monitoring system that is appropriate to the test. The detector shall be allowed to stabilize for 180 s. The intrusion signal or message output shall be monitored. If multiple sensitivity modes such as pulse c
35、ounting are available, any non-compliant modes shall be identified by the manufacturer. All compliant modes shall be tested. The following SWT temperature conditions shall apply during the test and shall be recorded at intervals sufficient to ensure consistent measurement: a) The temperature of the
36、background surface immediately behind the SWT shall be in the range 15 C to 25 C, and shall be horizontally uniform over that area to 2 C during calibration of the SWT. Over the whole background area it shall be measured at ten points. b) The averaged temperature difference between the background te
37、mperature and the SWT temperature shall be 3 C +/- 10 %. If it is greater, attenuation filters shall be placed directly over the detector lens or window to reduce proportionally the energy received by the detector. The procedure is described in Annex D.

The
39、 BDT verifies only the qualitative performance of a detector. It consists of a heat source equivalent to the human hand that can be moved across the field of view of the detector. An informative description is given in Annex E. The temperature of the source shall be not less than 3 C above the backg
40、round. A close-in walk test may be carried out as an alternative to using the BDT. 6.2.2 Basic test of detection capability A stimulus that is similar to that produced by the SWT is applied to the detector, using the BDT. Move the BDT perpendicularly across the centre line of the detection field at
41、a distance of not more than 1 m, and at a height where the manufacturer claims detection will occur. Move the BDT a distance of 1 m at a velocity of 0,5 m/s to 1,0 m/s. The detector shall produce an intrusion signal or message when exposed to an alarm stimulus both before and after being subjected t
42、o any test that may adversely affect its performance. 6.3 Walk testing Walk testing is accomplished by the controlled movement of a SWT across the field of view of the detector. The grade dependent velocities and attitudes to be used by the SWT are specified in Table 2. Walk tests shall not be repea
43、ted before a time interval of at least 20 s (or greater if specified by the manufacturer) has elapsed. An intrusion signal or message shall be generated during a (each) walk test to register a pass. If an individual walk test is failed, it shall be repeated twice more. Two passes out of the three te
44、sts shall constitute a passed test. General pass/fail criteria for all tests For a complete test series, 95 % or more of the tests shall be passed. 6.3.1 Standard walk test target (SWT) The SWT shall have the physical dimensions of 160 cm to 185 cm in height, shall weigh 70 kg 10 kg and shall wear c
45、lose-fitting clothing having an emissivity of greater than 80 % between 8 m to 14 m wavelength band. The averaged temperature difference between the SWT and the background shall be established. Temperatures shall be measured at five points on the body of the SWT, on the surface facing perpendicularl
46、y to the axis of the detector, and the background temperature close to each point measured at the same time. 1. Head. 2. Upper torso side. 3. Hand at body side. 4. Legs at knee. 5. Feet. Temperatures shall be measured using a non-contact thermometer or equivalent equipment, which shall be verified a
47、gainst the calibration heat source (6.3.3.1). The test house shall measure and calibrate at intervals that ensure conformance with the specified limits.

48、C/TS 50131-2-2:2004 The temperature differences at each body point are calculated, weighted and averaged. The informative detail calculation of the SWT temperature difference is given in Annex D. There shall be a means of calibration and control of the desired velocity at which the SWT is required t
49、o move. NOTE The use of a simulator/robot in place of the SWT is permitted, provided that it meets the specification of the SWT with regard to temperature. It is known as the simulated target. In case of conflict, a human walk test shall be the primary reference. 6.3.2 Standard walk test target calibration 6.3.2.1 A calibration heat source A heat source that has an absolutely constant temperature close to that of the human body is described in Annex F. 6.3.2.2 S
