It covers requirements additional to those given in BS 5873
8、 : Part 4. The tests described are intended to represent unauthorized attempts to gain access to secure storage furniture installed specifically for security purposes in educational institutions. The tests are designed to be applied to an article that is fully assembled and ready for use. Two securi
9、ty levels are specified, as follows: Security level G (General) for secure storage furniture to be used in areas where the risk of attack is small because the value of the contents of the secure storage is not sufficient to encourage entry attempts when the area is likely to be unoccupied. Security
10、level H (Heavy) for secure storage furniture to be used in areas where there is a real risk of attack because of the value of the contents of the secure storage or the isolation of its location. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of

20、ence should be made to the latest editions. 3 Classification Secure storage furniture shall be classified according to the level of security it is intended to provide, as follows. a) Security level G (General). Secure storage furniture which is intended for storage of relatively low value items, the
21、 value of which would not be sufficient to encourage entry attempts when the area in which the unit is placed is likely to be unoccupied. b) Security level H (Heavy). Secure storage furniture which is intended for storage of high value items, the value of which would put the furniture at risk of att
22、ack, and/or which is intended for use in isolated locations. 4 Security Secure storage furniture shall be tested when fully assembled and ready for use. The secure storage unit shall be subjected to the tests listed in table 1 for the relevant security level using the test procedures given in annex
23、A. It shall not be possible to remove the storage unit from its test mount, or to achieve access, using the times, means of attack and forces given in table 1. 5 Marking and labelling The secure storage units shall be marked permanently with the following information: a) the name and/or trademark of
24、 the manufacturer; b) the number and date of this British Standard, i.e. BS 5873 : Part 5 : 1998 1) ; c) the security level of the unit. 6 Instructions The secure storage unit shall be accompanied by instructions and recommendations for its secure attachment.BS 5873 : Part 5 : 1998 2 BSI 1998 2) For

Annex Annex A (normative) Methods of test for resistance to attack A.1 Principle Timed attempts are made using common hand-tools to remove the enti
26、re secure storage unit from a test mount or to gain entry into the interior and remove its contents. The hand-tools selected for the tests represent those which have been commonly used for attacks and which are widely available. The object of the methods of test is to assess whether the secure stora
27、ge unit can be removed entirely from its fixings or whether access to its contents can be achieved, either by opening the door or by deforming or penetrating it in such a way that the contents can be removed by hand or by a tool. Two security levels have been set (see table 1). A.2 General A.2.1 Tes
28、t mount The ease or difficulty with which the secure storage unit can be prised off a wall depends upon the strength of the wall itself. The secure storage unit shall therefore be test-mounted to a fixture of strength greater than that of the unit so that the assessment of its security, and mounting
29、 fasteners, if these are supplied, is independent of the mounting fixture. A.2.2 Test operatives and procedures A.2.2.1 Experience with a variety of designs and construction, gained during the development of the test procedures, has shown that it is impossible to entirely eliminate the human element
30、 from testing. In particular, the following points should be noted. a) Test operatives may become more adept at gaining access as more secure storage units are tested. b) Knowledge of the constructional details of a secure storage unit, either acquired or imparted, can facilitate gaining entry. c) T
31、he attacks are physically demanding. d) The variety of designs and construction of secure storage units precludes the establishment of a set of simple mechanical operations of specified magnitude. Secure storage units that prove resistant to entry by attack on one component or by one type of tool so
32、metimes yield easily when attacked at a different point or with another tool. A.2.2.2 As a consequence of the observations described in A.2.2.1a) and b), test operatives shall have previous experience of the testing of secure storage units, or similar products, for resistance to attack and shall be
33、allowed to examine the unit under test, as described in A.5.1.2, before commencing to attack it. A.2.2.3 As a consequence of the observation described in A.2.2.1c), care should be taken to ensure that the operatives have the necessary strength and stamina to perform the tests. A.2.2.4 As a consequen
34、ce of the observation described in A.2.2.1d), the test procedure involved requires that attacks are made using different combinations of tools and areas of the secure storage unit, either until the unit proves resistant to all approaches or until the combination most likely to effect entry has been
35、identified. In the latter case, the attack method is then continued in an attempt to gain entry. A.2.2.5 The hand-tools selected for the tests are specified in precise terms in order to standardize the attack test procedure to provide, so far as is possible, repeatable and reproducible results. A.3
36、Apparatus A.3.1 Test mount, comprising a surface to which the secure storage unit is affixed, having a strength and surface area greater than those of the unit to be tested. NOTE. Substantial timber beams, rag bolted to a brick or concrete wall (for wall-mounted tests) or floor (for floor-mounted te
37、sts) have been found to be satisfactory. A.3.2 Weights, or other means of applying a static force to the secure storage unit in downwards, upwards and sideways directions. A.3.3 Monobloc martensitic stainless steel table knife, conforming to ISO 8442. A.3.4 Ignition source, comprising a match flame
38、equivalent as specified in BS EN 1021-2 (to represent a smokers lighter). A.3.5 Propane powered brazing torch 2) . A.3.6 Club hammer, of mass 1.8 kg, conforming to BS 876. A.3.7 Flat cold chisel, overall length 200 mm and blade width 25 mm, conforming to BS 3066. A.3.8 Jemmy, hardened steel, of dime
39、nsions as shown in figure A.1. A.3.9 Flat blade screwdriver, (London Pattern) of blade length 450 mm, conforming to BS 2559. A.3.10 Hacksaw, with high speed steel flexible blade, for hand use, tooth pitch 1.0 mm, conforming to BS 1919. A.3.11 Battery-powered drill. A.3.12 Steel twist drill bits, of
40、diameter in the range 3 mm to 5 mm, conforming to BS 328 : Part 1. A.3.13 Impact hammer, comprising a cylindrical object having a mass of 6.5 kg supported from a pivot by a steel tube of 38 mm diameter and with a wall thickness of 2 mm. The distance between the pivot and the centre of gravity of the
41、 striker is 1 m. The pendulum arm is pivoted by a low fiction bearing as shown in figure A.2.

Figure A.2 Impact hammer A.4 Preparing the secure storage unit If the secure storage unit is supplied with fastening bolts or screws, use these to affix the unit to the test mount (A.3.1), otherwise use the fixings recommended by the manufacturer. Wall mounted units shall be mounted clear o
44、f the floor. Floor mounted units shall be mounted on the floor with no wall support. Units intended to be mounted simultaneously both to the wall and floor together shall be tested secured both to the floor and wall. Units intended to be fitted either to a wall or the floor shall be tested separatel
45、y secured to the wall and the floor using two separate samples. Secure all secure storage units so that there is unrestricted access to the top and any exposed side. A.5 Procedure A.5.1 General A.5.1.1 Select the appropriate tests for the security level for the unit under test (see table 1). A.5.1.2
46、 Thoroughly inspect the secure storage unit noting any points of apparent weakness. Begin all tests, with the exception of A.5.2 and A.5.3, at these points. A.5.1.3 Perform the tests in the order listed in table 1, ceasing if the secure storage unit fails any test. If the unit satisfies the tests, r
47、epeat them on another unit with a different test operative. A.5.1.4 The times for resistance to the various attacks given in A.5.4 to A.5.10 are exclusive of any periods of rest for the operative that may be required. A.5.2 Resistance to vertical downwards or upwards static load (wall mounted cupboa
48、rds or wall/floor mounted lockers when using wall mounting attachments only) Apply to the edges of the top or any other effective location, a downwards static force as specified in table 1 by means of the weights or other means (A.3.2). Remove the force after 30 s and determine if the secure storage
49、 unit has been detached from the test mount. Repeat the test procedure applying the static force specified in table 1 upwards to the edges of the top or bottom or any other effective location. A.5.3 Resistance to a horizontal static load Apply to the secure storage unit, in the centre of one side, a horizontal static load as specified in table 1. Remove the load after 30 s and determine whether the secure storage unit has been detached from the test mount. BSI 1998 5 BS 5873 : Part 5 : 1998 A.5.4 Resistance to
