3.2 Specimens to be supplied for testing

The following shall be observed subsequent to the acceptance of an application for approval:

1. The applicant shall supply an agreed number of specimens.
2. The number of specimens to be supplied for test is dependent upon the test schedule specified for the product type, the classification sought by the applicant, together with the range of design variations and alternative hardware to be covered by the assessment.

All specimens shall be complete with associated hardware, fixings and instructions. Additional specimens of hardware may be required for separate tests.

1. Additional component parts, such as spare keys, may be requested for testing purposes.
2. The type and configuration of specimens selected for testing shall be at the discretion of the test laboratory. The normal size and configuration of the product and its intended application shall be taken into account. Where the product is offered in a range of sizes and configurations, specimens of those sizes and configurations likely to be least effective against attack shall be chosen to ensure the test results are representative of the complete range.
3. The test specimens shall incorporate optional features/accessories that could decrease the cylinder’s manipulation resistance. They shall not incorporate optional features/accessories that could increase the intruder resistance provided by the product (e.g. chemicals or other additives designed to temporarily enhance the cylinder’s resistance to manipulation).
4. All specimens shall be supplied complete with specified fixings for secure installation and installed by the manufacturer or their nominated representative.
5. The laboratory may request additional components or elements of products for testing purposes.
6. If a prototype product or associated hardware/accessories is supplied for testing, then classification cannot not be provided 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.

Note: Changes to production methods (e.g. machining to casting) or designs between prototype and final production stages may affect the products’ performance. Therefore, it is not automatically possible to attribute security ratings achieved by prototype test samples to subsequent series production.

classification box, the instructions supplied with the product shall reflect the limitations noted within the fire assessment reports that support the claims of suitability made. Where reference is made to the fire assessment report, copies of that report shall be accessible to those likely to wish to purchase or install the product.

1. It is recommended that all fixings and security features on products primarily intended for use in commercial properties are, as far as is reasonably possible and where applicable, tamper resistant on the non-attack side to prevent surreptitious interference of the designed level of security by an attacker’s accomplice.

• Any exposed fixings that can be accessed from the attack side may be exploited as part of the manual attack tests.

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 attack test.

• Test method

Mount the cylinders, including any reinforcement or protection devices supplied with them as defined in clause 4.2.9.2 in accordance with the manufacturer’s instructions, with the attack side of the cylinder confronting the test operative.

The attack tests conducted shall be those most likely to cause the specimen to fail to meet the requirements defined in clause 3.4.10.

Each individual attack test shall be continued until either:

• The objective is achieved, that is, the lock driving mechanism can be operated without using the original key; or
• The maximum test duration defined in Table 7 is exceeded; or

(c) The team leader decides that the attack is ineffective for classification purposes.

Each individual attack test shall be undertaken on a new specimen.

A ‘0’ shall be entered into box 9 when classifying:

• cylinders that have not been tested in accordance with clause 4.2.8; or
• cylinder that have failed to comply with the requirements of manipulation resistance classification ‘1’ defined in clause 3.4.9; or
