LPS 1228 Issue 1.2 Specification for testing and classifying the burglary resistance of office furniture – lightweight containers

This standard describes tests for classifying the burglary resistance to physical attack of office furniture – lightweight containers, for example filing cabinets and document cabinets. The burglary resistance of the product itself and any in-situ hardware, such as locks and hinges, are tested.

The burglary resistance performance of a lightweight container is classified regardless of design or materials used in construction.

The resistance to manipulation of any fitted lock(s) is not tested.

LIGHTWEIGHT CONTAINER

A self-contained system of physical security elements used to store documents, cash and valuables and accessed through lockable opening element(s).

BURGLARY RESISTANCE

The capacity of a lightweight container to withstand the attempt of a forced entry.

SECURITY CLASSIFICATION

Indication of the degree of resistance of a lightweight container to forced entry.

SECURITY CLASSIFICATION EXPECTATION

The anticipated classification level for which the lightweight container was designed.

OPENING ELEMENT

A door, drawer or other feature that facilitates access to the interior of the lightweight container was designed.

LATCHED CONDITION

Every opening element of a lightweight container is closed with any automatic latching mechanism engaged. Closed elements of the product cannot be opened without a key, force or damage.

This is the minimum locked condition. The burglary resistance of the product will be adjudged for minimum resistance with the locking mechanism in this state.

LOCKED CONDITION

Every opening element of a lightweight container is closed, latched and deadlocked.

This is the optimum locked condition and the burglary resistance of the product will be adjudged with the locking mechanism in this state. This condition may be the same for the minimum locked condition if the locking logic does not include an automatic latch state.

MANUAL INTERVENTION ATTACK TEST

A manual attempt at gaining forced partial or full access with and/or without the aid of tools.

WORKING TIME (RESISTANCE TIME) The aggregate time of an attack test.

TOTAL TEST TIME

The maximum duration of an individual attack test which is the sum of the accrued working time, rest time of an operative for well-being and safety reasons, time to change tools or exchange defective expendable tool elements and any inspection time called by the team leader.

PARTIAL ACCESS

Formation of a hand-hole size aperture of sufficient size which allows complete passage of a test block, according to 8.3.1, to the interior of the lightweight container, through which small or flexible items of value may be removed, or information about the contents gained.

COMPLETE ACCESS

Change of state of the lightweight container by opening a closed element after overcoming the integrity of the locking system, or formation of an aperture which allows complete passage of a test block, according to 8.3.2, to the interior of the container through which larger items of value can be removed.

INFORMATION TO BE SUPPLIED BY APPLICANT

Prior to examination and testing an applicant shall provide comprehensive information about the product to the certification authority for consideration. All documents shall be dated and given a reference number and issue description. If the applicant is not the manufacturer then an application must be accompanied by written permission for testing from the manufacturer.

SPECIMENS TO BE SUPPLIED FOR TESTING

Subsequent to the certification authority’s acceptance of an application for approval, the following shall be observed:

1. The applicant shall supply an agreed number of specimens. If the product is in series production, specimens shall be selected by a certification authority representative.
2. If prototype specimens are supplied for testing, approval will not be given until the drawings for subsequent series production have been examined and confirmed that they accord with the tested prototype or that any changes will not reduce the security rating.
3. Additional component parts of some products may be requested for testing purposes.
4. When the product incorporates advances or changes in technology, then additional sample pieces, parts or sections can be requested for evaluation prior to the supply of the agreed specimens.
5. The applicant shall supply at least three specimens for testing. The specimens shall be complete with any associated hardware supplied or fitted. Depending on the product, other specimens may be necessary.
6. The size of specimens for testing shall be at the discretion of the test laboratory. The normal size of the product and intended application shall be taken into account. Where the product is manufactured and intended for use in a range of sizes, a size of specimen likely to be least effective against attack shall be chosen to ensure the test results are representative for the complete range. Where relevant, specific fixings/anchorage system for secure installation shall be supplied.

5. DESIGN REQUIREMENTS

LOCKS

Only integral lock(s) shall be used.

Lock(s) shall have the minimum of 1000 effective differs and mastered key lock(s) shall not reduce the security provided by a minimum of 1000 effective differs.

Lock mounting screws, nuts and rivets etc. on which the security of the protection device depends shall be concealed when the device is in the locked condition.

OPTIONAL FEATURES

Time Locks/Time Delay Locks

These may be mounted in addition to the locks specified in 5.1.

Cable Entry Holes (less than 100mm2)

A cable entry hole shall not be greater than 100 mm².

Where cable entry holes are present but not used they shall be obstructed and/or, such that the security integrity of the lightweight container is not compromised.

Cable entry holes and respective protection offered shall be shown on the construction drawings and be present in the test specimens.

Anchorage

Any facilities for secure installation present but not used should not afford access to the interior of the container. This includes provision for blind apertures.

EXAMINATION

All information and drawings supplied will be reviewed to ensure suitability for testing and approval purposes.

CONFORMITY BETWEEN SPECIMENS AND DOCUMENTATION

Prior to testing, the specimens shall be visually examined for conformity with the details supplied by the applicant.

If it is discovered that a specimen does not so conform, testing will not be performed until the drawings and documents have been modified or the specimens have been altered by the manufacturer.

If a lack of conformity of the specimens and construction drawings is discovered during the testing, the applicant will be required to amend the construction drawings and documents accordingly. The applicant shall be notified thereof whilst evaluation of the product is in progress. Any test may be discontinued and repeated on another specimen if it is concluded that as a result of the non-conformity the attack should have been directed at an alternative location.

Locking

On lightweight containers intended to be opened in normal use, provision of a suitable lock(s) shall be verified and the design/attachment of the lock(s) reviewed for any weakness that may be exploited during testing. The locking logic shall also be reviewed in order to determine the minimum and optimum locked conditions for test purposes.

• Security Features

Security features shall be reviewed to ensure that, as far as is reasonably possible, they are tamper resistant so as to prevent surreptitious interference of the designed level of security prior to attack.

General laboratory procedures, confidential handling of specimens, event record requirements and presentation of the test report shall be in accordance with the requirements specified in EN 45001.

The overall objective is to confirm the security classification expectation of a lightweight container by conducting a series of manual intervention tests. Requirements for each security classification are given in Table 1. Overall classification is confirmed if the requirements for the anticipated class are met.

MANUAL INTERVENTION ATTACK TESTS

Using tools from the tool kit appropriate to the security classification expected (see Table 1), or by manual manipulation, attacks are made against the product with a view to allowing free entry of one of the test blocks specified in Clause 8.3 into the lightweight container or access to a protected item. The working time (resistance time) shall be recorded in order to determine whether the lightweight container is capable of meeting the expected security classification. For the classification expectation of this style of test to be verified, all security aspects shall withstand attack.

Test Block To Measure Complete Access

A test block of 350mm diameter cross section and 400mm length shall be used to measure complete access.

The tolerance shall be ± 3mm.

ATTACK TOOLS

The tool manifest for the manual intervention attack tests and ascribed tool kit is as follows:

MANUAL INTERVENTION ATTACK TESTS

TEST FACILITY

The apparatus for this test shall consist of a floorbase suitable for mounting a lightweight container in its normal attitude. The floorbase shall be free from movement for the duration of testing. The manifest of attack tools specified in Clause 9 complete the apparatus requirement.

TEST TEAM

The test team shall comprise a team leader whose function is to direct, time, compile an event record and control the testing work on a product specimen and a test operative whose prime function is to carry out the testing work on the specimen as directed by the team leader.

At any time during testing the team leader may substitute himself for the test operative, the operative assuming the role of timekeeper whilst maintaining the event record.

A different test operative may be used for different styles of attack but only one operative (other than the team leader) shall partake in any individual test.

TEST METHOD

Locate the lightweight container under test on the appropriate floorbase.

Secure any opening element in the minimum or optimum locked condition, as appropriate.

Attack tools of the appropriate kit relative to the security rating expectation shall be arranged, adjacent to the test frame, ready for immediate use.

A series of attack tests shall then be undertaken with each continued until, (i) the objective is achieved, (ii) the maximum test duration is exceeded, or (iii) the team leader decides that the attack is ineffective for classification purposes.

Tests on the locking system shall be undertaken in both the minimum and optimum locked conditions, as applicable.

Attack tests shall only be aimed at areas or features which in the opinion of the team leader have not been weakened by previous tests.

During each individual attack test the timing device used to measure test duration shall remain activated. The resolution of this device shall be at least 1 second. The timing device(s) used to record working time shall have a resolution of at least 0.01 second. At the conclusion of the test, the working time shall be rounded to the next full second.
