30、 the correct operation of the detector to the specification provided 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 I. BS EN 50131-2-7-2:2012Copyright European Committee

32、s in the measurement and tests laboratory shall be those specified in EN 60068-1:1994, 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 6.2.2 General detection testing environment and procedures Manufacturers documented inst
33、ructions regarding mounting and operation shall be read and applied to all tests. 6.2.2.1 Testing environment The detectors or sensor elements will be mounted according to the manufacturers description on the monitored object (glass window or door glass pane). Some tests will be performed on the mon
34、itored object, others will be performed on panes (unframed window), where the detectors are mounted directly on. 6.2.2.2 Test procedures The tests will be performed with the types of glass claimed by the manufacturer. These tests will be performed with the sizes and thicknesses of glass as specified
35、 in Annex A. Additionally, tests will be performed with the maximum size claimed by the manufacturer if this is greater than the maximum size specified in Annex A. Additional tests will be performed with the thinnest glass claimed by the manufacturer, if this is thinner than the minimum thickness sp
36、ecified in Annex A. The detector shall be connected to the nominal supply voltage and connected to the monitoring system that is appropriate to the test. The detector shall be allowed to stabilise for 180 s. The intrusion signal or message output shall be monitored. If multiple sensitivity modes are
37、 available, any non-compliant modes shall be identified by the manufacturer. All compliant modes shall be tested. 6.3 Basic Detection Test 6.3.1 General The purpose of the Basic Detection Test is to verify that a detector is still operational after a test or tests has/have been carried out. The Basi
38、c Detection Test verifies only the qualitative performance of the detector. The Basic Detection Test is performed using the BTS. 6.3.2 Basic Test Source For functional verification there shall be a device available which will simulate a glass breakage or destruction, without breaking the glass (BTS)
39、, alternatively a pane of standard sized glass (see Annex A) can be broken to verify the detection. The Basic Test Source (BTS) which is specified by the manufacturer simulates the breaking of a standard glass window by the low energy attack test. This device should be a test device, which is specif
40、ied for testing through simulation of a glass break from or recommended by the manufacturer. This device should simulate a glass breakage or destruction, by pressing the device onto the monitored glass and simulating a sound, frequency or condition, which needs to be detected.

42、r message when a test device (BTS) is used to simulate a glass breakage. The test will be performed according to the manufacturers instructions after the first installation, to verify, that all detectors are installed properly. It will be performed again, after or / and during the environmental test
43、s under the same conditions the tests had been performed the first time, to verify that the detectors will still function the way, the manufacturer claims to support (e.g. detection range) and to compare this results with the results of the initial test. If the test is not compatible with the detect
44、or, use the manufacturers information to generate the correct algorithm. The detector(s) shall produce an intrusion signal or message when exposed to an alarm stimulus both before and after being subjected to any test that may adversely affect its performance. 6.4 Performance tests 6.4.1 General The
45、 general test conditions of 6.2.2 shall apply to all tests in this series. Detection performance shall be tested against the manufacturers documented claims. Any variable controls shall be set to the values recommended by the manufacturer to achieve the claimed performance. The detectors shall be as
46、sessed in the specified test environment. 6.4.2 Verification of detection performance 6.4.2.1 General All performance tests are based on physical destruction characteristics (e.g. the sound of breakage) of the size, thickness and types of glass claimed to be supported by the manufacturer including t
47、he standard glass types listed in Annex A, if claimed to be supported by the manufacturer. 6.4.2.2 Sensitivity performance test The test will be performed for each glass type claimed to be supported by the manufacturer. Each glass pane will be positioned on on top of the support / distance pieces, t
48、o ensure that the glass break signal can reach the detectors undampened. Three detectors shall be mounted according to the manufacturers installation instructions on the monitored glass (if a simultaneous installation is not supported, the test shall be performed for each detector separately), at the maximum distance of the planned
