What is the security door class A standard

Since April 1, the new national standard for anti-theft doors GB17565 2007 "General Technical Conditions for Anti-theft Security Doors" standard has been officially implemented. Compared with the old standard, the new standard strictly regulates the safety level of the security door, the thickness of the door frame and the number of locking points.

The new standard increases the anti-theft security level from the original 3 levels of "C", "B" and "A" to 4 levels of "A", "B", "C" and "D". The new anti-theft security level is coded with the alphabets "J", "Y", "B", "D". A is the highest level, and so on.

The anti-theft security performance of the anti-theft door is different for different anti-theft levels. For example, the anti-vandalism time: Class A security door shall not be less than 30 minutes, Class B shall not be less than 15 minutes, Class C shall not be less than 10 minutes, and Class D shall not be less than 6 minutes; The number of locking points between the door frame and the door leaf shall not be less than 12, 10, 8 and 6 respectively for Class A, B, C and D security doors; The thickness of the steel plate of the door frame should be 2mm, 2mm, and D respectively.

Consumers can choose the security door they want according to their needs.

The old specification: (the lock of the anti-theft door is divided into A, B, C three levels, C level security is the highest, followed by B level, A level lock is allowed to be installed on the security door of the lowest one, requiring anti-technical opening (that is, the person with unlocking technology to open or open with a master key) time is not less than 1 minute. Level A Requirements:

All steel, casement fully enclosed, ordinary mechanical hand tools and portable power tools cooperate with each other, its weakest link can resist the net time of abnormal opening 15 minutes, or should not be able to cut out a 615 square centimeter hole through the door body).

All-steel, casement fully enclosed security door, under the mutual cooperation of ordinary mechanical hand tools, portable power tools, etc., its weakest link can resist abnormal opening of the net time is greater than or equal to 15 minutes, or should not be able to cut out a 615 square centimeter hole through the door body. Such an security door proves to meet the A-level standard.

Some specific ones such as:

The splice material should be tightly connected with the window frame, and at the same time sealed with caulking paste, not shaking, the screw spacing should be less than or equal to 600 mm, and both ends of the lining reinforced steel should be fixed firmly with the hole.

Switch components: casement, sliding or rotating windows should be closed tightly.

Frame and wall connection: the window frame should be horizontal and vertical, the height is consistent, the spacing of the fixing piece should be less than or equal to 600 mm, the frame and the wall should be firmly connected, the gap should be filled with elastic material, the surface seam paste sealing, no cracks.

Drainage holes: Drainage holes should be positioned correctly and at the same time be unobstructed.

Only those who can meet such standards can be considered A-level.

National Standard This should be the lock cylinder standard.

Class A is the most primitive and most insecure lock cylinder, the owner's key is flat, only single-sided single-row bullet slot, some cross keys are also A-level, such a lock can be opened in about two or three minutes, and the familiar hand will be faster.
