Door To Class IV

in: News

Class burglary door is defined by Table 1, on minimum value of the resistance of the EU door series of tests using different tools. Moreover, under partial access means the possibility of penetration through the doorway of the template with a diameter not less than 125 mm, with full access – a template with a diameter less than 350 mm. Table I. Class ustoychivostiMinimalnoe resistance value EChastichny dostupPolny dostupI3050II5080III80120IV120180 For example, I class burglary doors means that the using the manual lever tool of the third group, ie arm with attachments, claw hammer, crowbar or breakage of a length not exceeding 750 mm, the time required to obtain partial and full access through a door must at least 5 minutes and 9, respectively. (Tools of the group assigned to the values of coefficients k and b, equal to 5.) Door To Class IV resistance to cracking the appropriate time should be at least 23, and 35 minutes. Necessary note that the stability of the class door to cracking is determined by the minimum value of EC obtained by comparing different methods of hacking and using different tools.

So The above figures do not mean that any door I can hack class with scrap from the mount in less than 10 minutes. It is possible that used in the door system of active and passive bolts completely rule it out breaking in this way. In this scenario, I-st class door means that there is no other way, for example, requiring the use of special electric cutting tool with an abrasive disc, which, in principle, allows fast enough to get through this door.
