---

The C₂H₂ and 0₂ volumes shall be corrected to conditions of 20°C and 1 013 hPa, and shall have a tolerance of ± 5 %.

The gas volume charge shall be calculated using the following formula:

^Charge ⁼ 50 I < 50% У internal space <100 I

NOTE Internal space is defined in 3.8.

The calculated volume shall be rounded-up to the next full number.

Gas flow/charge measuring equipment capable of reaching the requirements of 10.3 (with volumes within the tolerance and homogeneity). For the storage of the gas volume, the laboratory shall use a flexible container(s). The properties of the flexible container(s) in respect to the dimensions, material and stability shall be chosen so that these will not influence the results of the gas attack test (e.g. back pressure < 1 hPa , no absorption of energy).

For reasons of worst case test conditions and reproducibility, the ignition device and the flexible container(s) for the gas charge shall be positioned near the middle of the internal space of the ATM safe (see 3.8). The sequence of the procedure is as follows:

• Fill the gas charge container(s) with air or inert gas to check it for leakage and position;

• Empty the gas charge container(s);

• Close and lock the door;

• Fill the flexible container(s) with the stoichiometric and homogenous gas charge;

• Ignite the charge.

NOTE To obtain a homogeneous gas charge, the mixing of the gas components can either be done before (e.g. mixing by devices such as a nozzle) or after (e.g. mixing by a circulation pump) filling into the flexible container(s). A webcam may be used to check for leakage and container position.

After detonation, the tool attack shall be performed until partial access (as defined in 7.4.a)) is achieved, or until the required post-ignition resistance value (see Table 2) is reached. The tool attack shall be recorded as a post­detonation tool attack.

This post-detonation tool attack is limited to the use of attack tool categories А, В, C and D.

Any post-detonation tool attack shall be continued until no more information necessary for determining the post­detonation resistance value can be reasonably expected.

Calculate the resistance value for the tool attack using the following formula:

^{R V}PD ^VPD ⁽³⁾

where

RV_PD is the post-detonation resistance value;

is the sum of all operating times for the post-detonation tool attacks;

c is the highest tool coefficient of the attack tool used in the post-detonation tool attacks (see

Annex A);

BV_PD is the sum of basic values for all attack tools used only in the post-detonation tool attacks.

The calculated value shall be rounded-up to the next full number: it represents the resistance value in RU for the post-detonation work.

Before the ignition:

• Record observations, volumes, gas charge and mixing procedure.

After the ignition:

• Record observations describing the effect on the test specimen.

For the post-detonation tool attack test, record in chronological order at least the following details:

• point of attack;

• — tools used;

• record of all operating times;

• measurements made and record of events;

• — reference to any photographic or video records made;

• resistance value in RU.

If the requirement (e.g. ATM safe III GAS) is met, the product may be marked with the letters ‘GAS’ after the grade number. Products shall not be marked with a grade number which is higher than that achieved in the tool attack tests (see Clause 7).

11. Core drilling test

    1. Principle

The test establishes the resistance to a burglary attack using core drilling equipment as the principle tool. The test applies only to safes, strongroom doors and strongrooms, and is carried out only if the applicant wishes to claim CD designation.

The core drilling test may be carried out on the test specimens used for tool attack tests. Alternatively, if agreed by the testing laboratory, another panel whose construction is identical with that of the test specimen used for the tool attack may be used.

Testing shall be carried out with electric power tools of category D in accordance with Table A. 10, and with core bits of (150 ± 5) mm diameter of category D or S in accordance with Table A.12. Preparatory work prior to core drilling is permitted with tools of categories В and C in accordance with Table A.11. The use of these tools is limited to 150 RU. The resistance value for this preparatory work shall be calculated in accordance with 7.9.

Testing shall be carried out with electric power tools of tool category S in accordance with Table A.10, and with core bits of (150 ± 5) mm diameter or (400 ± 10) mm diameter of category S in accordance with Table A.12. It is not allowable to change the diameter of core drills after the test has commenced.

The following ancillary tools are permitted to assist in the core drill test:

• thermal tools (see Table A.11, tool category C) or grinding/slitting tools (see Table A.10, tool category C);

• hammer with a head weight of 1,5 kg (see Table A.5, tool category A);

• any number of screwdrivers and chisels (see Table A.1, tool category A).

The resistance value from the use of the ancillary tools is calculated according to 7.9 with the respective basic values and tool coefficient of 35 RU/min. The use of these tools is limited to 800 RU. The calculated resistance value of the ancillary tools adds to the resistance value of the core drill equipment.

Core drilling shall be used to create a partial access (as defined in 7.4 a)) through the test specimen of safes as well as a complete access (as defined in 7.4 b)) through the test specimen of strongroom doors and strongrooms. During the test, the core bit may be changed.

The core drilling test may be terminated, and the requirements for CD designation deemed to have been achieved; if the tester decides that, because of slow penetration, or because the drilling is repeatedly halted or the bit damaged, there is sufficient evidence to suggest that the resistance value requirement in accordance with Table 1 (safes) respectively Table 3 (strongroom doors and strongrooms) would be achieved.

NOTE 1 For positioning the test equipment and fixing it to the test specimen, other tools can be used, but they should be used only for this purpose and should not otherwise influence the time of penetration.

NOTE 2 A complete access (test blocks in accordance with 7.3.3) on strongroom doors and strongrooms can be achieved by a single penetration or several overlapping penetrations.

The resistance value for making a partial access on safes as well as a complete access on strongroom doors and strongrooms shall be calculated according to 7.9.

Basic values for tools used for fixing or positioning of the core drilling equipment shall not be included in the calculation; neither shall the time taken for positioning or fixing be included in the operating time. Time used to ‘sharpen’ or otherwise treat a core bit to restore its cutting ability shall be counted as operating time.

If the requirement (e.g. safe V CD, strongroom door XII CD) is met, the product may be marked with the letters 'CD’ after the grade number. Products shall not be marked with a grade number which is higher than that achieved in the tools attack tests (see Clause 7).

Attack tools

In this annex, tool coefficients and basic values are given for each tool (see Tables A.1 to A. 14) and tool category (А, В, C, D and S) which are allowed to be used in the tool attack test. In addition, the intended use of the tool is described.

NOTE In some cases, the basic value also will vary within a tool category.

Tools of Tables A.1 to A.6 are only used manually, and without an external power supply. Tools of Tables A.7 to A.10 are used with external supply terminals and usually (with the exception of tool category A) depend on external sources of power. Tools of Tables A.7, A.8 and A.10 can be used with cutting and/or cooling fluids.

Tools shall be used for the purpose for which they are designed. If a tool replaces another type of tool, the coefficient of the replaced or simulated tool (if higher) is applicable.

EXAMPLE If a screwdriver is used as a punch then it shall not be regarded as a hand (dis)assembling tool but as a tool specific accessory with a basic value of 1 resistance unit (RU).
