5.4 Door mass
No tests.
5.5 Fire resistance
Fire resistance shall conform to annex A.
5.6 Safety
No tests.
5.7 Corrosion resistance and Test of operation at extremes of temperatures
NOTE Reference is made to annex B.
The cylinder shall conform to 4.7.1.
The two cylinders shall be stabilised before the test by being kept at a steady temperature of 18 °C ± 4°C and a humidity of 60%, ± 5% for a period of at least 48 h.
The keys shall be kept separately at the same temperature mentioned above during the following tests.
The two cylinders shall be cooled gradually by decreasing the temperature at a rate of 10° C, ± I °C per hour until a temperature of – 20 °C ± 2 °C is attained. The test temperature shall be maintained for a minimum of 10 mm and a maximum of 20 mm, after which period each cylinder shall be operated with its correct key in the laboratory at ambient temperature at least once within 5 attempts within 5 mm.
The keys shall again be kept at 18 °C ± 4 °C while the cylinders are reheated gradually at a rate of 10°C ± 1°C per hour until a temperature of 80 °C ± 2 °C is attained. The test temperature shall be maintained for a minimum of 10 mm and a maximum of 20 mm after which period each cylinder shall be operated with its correct key in the laboratory at ambient temperature at least once within 5 attempts within 5 mm.
5.8 Key related Security
5.8.1 Minimum numbers of effective differs
Check in accordance with 4.8.2, based on manufacturers information.
5.8.2 Minimum number of movable detainer
Check in accordance with 4.8.3, based on manufacturers information.
5.8.3 Maximum number of identical steps
Check in accordance with 4.8.4, based on manufacturers information.
5.8.4 Direct coding on key
Check in accordance with 4.8.5, based on manufacturers information.
5.8.5 Operation of the security mechanism
The security mechanism shall conform to 4.8.6.
The cylinders shall be fitted in a metal fixture as illustrated in annex C, Figure C.5 having the means for applying a known torque to a key inserted in the cylinder.
After verification of the function using the correct key, attempts shall be made to operate the cylinder by the next closest keys, in accordance with the required security grade.
For security grades 1, 2 and 3, the tests shall be performed on new cylinders.
For security grades 4, 5 and 6, the tests shall be performed on cylinders that have first been subjected to the appropriate cycles for durability specified in 4.3.
5.8.6 Torque resistance of plug and/or cylinder
The torque resistance of plug and/or cylinder shall conform to 4.8.7 or 4.9.5.The cylinders shall be mounted in the metal fixture illustrated in annex C, Figure C.5 in accordance with the manufacturers instructions. A torque shall be applied to the plug by an appropriate tool. If the torque required cannot be applied, the cylinder shall be deemed to have passed the test.
5.9 Attack resistance
5.9.1 Resistance to drilling
The lock shall resist drilling in accordance with 4.9.1.
For attack resistance grades I and 2, two cylinders shall be tested in an apparatus as illustrated in annex C, Figure C.2.
The cylinders shall be mounted in a fixture with provision for the fitting of any necessary reinforcements or protection devices supplied with the cylinder. A 700 W +1- 10 % (power consumption) hand drilling machine with a speed of 500 rpm to 800 rpm shall be mounted on a sliding block. A force not exceeding 300 N ± 5 % shall be applied axially to the drill without shock.
