Technical Requirements for Lock Safety — Part 2: Burglary-Resistant Locks
Scope
This document specifies the classification, security levels, and composition of burglary-resistant locks, safety requirements for mechanical burglary-resistant locks, safety requirements for electronic burglary-resistant locks, describes test methods, and establishes inspection rules.
This document applies to the design, manufacture, and inspection of burglary-resistant locks.
Normative References
The following documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including all amendments) applies.
Terms and Definitions, Abbreviations
3.1 Terms and Definitions
The terms and definitions defined in GB/T 36920-2018 and the following apply to this document.
3.1.1
Burglary-resistant lock
A lock that controls the opening and closing of mechanical actuators through mechanical transmission or electronic identification and processing of relevant information, with certain anti-destruction capabilities, anti-technical opening, and meeting specified security levels.
3.1.2
Mechanical burglary-resistant lock
A burglary-resistant lock that uses a mechanical transmission device to control the opening and closing of the lock and meets the specified security level.
3.1.3
Electronic burglary-resistant lock
A burglary-resistant lock that electronically identifies and processes relevant information to control electromechanical actuators for opening and closing, meeting the specified security level.
Note: Includes electronic locks, smart locks, and other locks with burglary-resistant properties that meet the specified security level.
3.1.4
Digital key
A carrier containing digitally encoded information used to control the opening and closing of electronic burglary-resistant locks.
3.1.5
PIN key (Personal Identification Number key)
A personal identification code used to control the opening and closing of electronic burglary-resistant locks.
3.1.6
Biometric key
Human biometric information (e.g., fingerprints, iris, finger veins, facial features) used to control the opening and closing of electronic burglary-resistant locks.
3.1.7
Drilling resistant
The ability to resist being opened by a toggle tool after being drilled with a portable electric drill.
3.1.8
Sawing resistant
The ability to resist cutting the lock bolt and other parts with a hacksaw, causing the burglary-resistant lock to lose its function.
3.1.9
Prying resistant
The ability to resist the use of various crowbars, screwdrivers, or wire-driving tools to pry weak parts of the lock, resulting in the burglary-resistant lock being opened.
3.1.10
Pulling resistant
The ability to resist being pulled by a pulling tool within a specified time, causing the lock to be opened.
3.1.11
Striking resistant
The ability to resist the opening of a burglary-resistant lock by impact with a specified impact tool after a certain period in the locked state.
3.1.12
Professional opening resistant
The ability to prevent a professional with knowledge of the lock from opening it using non-destructive professional methods (including specialized tools).
3.1.13
Deformed pin
A specially shaped pin installed in the pin hole of the lock body to prevent the lock from being opened using specialized tools.
3.2 Abbreviations
The following abbreviations apply to this document:
FAR: False Acceptance Rate
FRR: False Rejection Rate
PIN: Personal Identification Number
Classification, Security Levels, and Composition
4.1 Classification
Burglary-resistant locks are divided into:
a) Mechanical burglary-resistant locks, further classified by structure into:
Mortise-type mechanical burglary-resistant locks
Externally mounted mechanical burglary-resistant locks
Password-type mechanical burglary-resistant locks
b) Electronic burglary-resistant locks, further classified by networking mode into:
Stand-alone electronic burglary-resistant locks
Networked electronic burglary-resistant locks
4.2 Security Levels
4.2.1 Security Levels of Mechanical Burglary-Resistant Locks
Classified into:
Class A (lowest security level)
Class B
Class C (highest security level)
4.2.2 Security Levels of Electronic Burglary-Resistant Locks
Classified into:
Class A (lowest security level)
Class B
Class C (highest security level)
4.3 Composition of Burglary-Resistant Locks
4.3.1 Mechanical Burglary-Resistant Locks
Mortise-type: Mainly composed of a cover plate, lock body, lock cylinder, handle, and key.
Externally mounted: Mainly composed of a lock body shell, lock bolt, safety mechanism, handle, latch bolt, lock cylinder, and key.
Password-type: Mainly composed of a lock body shell, lock bolt, steering plate, and password dial.
4.3.2 Electronic Burglary-Resistant Locks
Modular components include:
Interaction module (display, voice, etc.)
Recognition module (card reader, keypad, biometric recognition, etc.)
Main control module
Storage module
Security module
Actuator
Power module
(Networked models additionally include a communication module and client application.)
