GJB2805B-2021 "Technical Requirements for Anti-Theft in Ordnance Warehouses" is a national standard aimed at regulating the construction of anti-theft facilities and technical management in ordnance warehouses to enhance their security protection capabilities. Below is a basic introduction:

I. Standard Overview

• Release and Implementation: Issued by the National Standard - General Armament Department on July 6, 2021, and implemented on September 1, 2021, replacing the 2002 version GJB2805A-2002 "Technical Requirements for Anti-Theft in Rear Ordnance Warehouses."
• Scope of Application: Applicable to warehouses storing ordnance equipment and materials, such as storage and supply bases, campaign warehouses, and unit-affiliated warehouses, covering the design, manufacturing, installation, and management of anti-theft facilities.
• Core Objective: Through standardized requirements, ensure that ordnance warehouses possess efficient anti-theft capabilities on the basis of fire and explosion resistance, safeguarding the security of weapons and equipment.

II. Core Technical Requirements

1. Materials and Structural Design

• Material Selection: Use high-strength alloy materials or steel that comply with national defense standards (e.g., main steel plate thickness ≥4mm), with pressure resistance, wear resistance, fire resistance, and corrosion resistance.
• Structural Design: The door body must have good sealing, using designs such as rubber sealing strips to ensure no light leakage, no air leakage, and no water leakage, preventing external harmful gases and flames from entering. The connection between the door frame and door body must be sturdy, with no fewer than 2 hinges, an opening angle of up to 180 degrees, and locking devices operable only from the inside to prevent external damage.

2. Anti-Theft and Safety Performance

• Anti-Destruction Capability: Anti-theft levels are divided into Level 1 (resistance to destruction time ≥40 minutes), requiring protection against common mechanical tools (e.g., knives, pliers) and portable power tools (e.g., hand drills). Locks must have high security, such as mechanical combination locks, electronic combination locks, or concealed beam locks, with a key capacity of ≥100,000, a cross-keying rate ≤0.03%, and anti-technical opening time ≥5 minutes (Level 1 anti-theft).
• Additional Functions: Integrated with intelligent monitoring designs, some door bodies are equipped with alarm systems to achieve multiple layers of protection.

3. Testing and Maintenance

• Safety Testing: Before use, doors must pass rigorous tests for explosion resistance, anti-theft performance, and sealing to ensure compliance with standards.
• Regular Maintenance: Develop inspection plans to check components such as door bodies, locks, and sealing strips, record maintenance activities, and ensure long-term reliable operation.

III. Key Facilities and Applications

• Main Facilities: Include explosion-proof doors, blast-resistant doors, moisture-proof sealed doors, and equipment room protective doors, which must simultaneously meet requirements for explosion resistance, fire resistance, moisture resistance, and anti-theft.
• Typical Scenarios: Used in warehouses storing flammable and explosive weapons and precision equipment to ensure the safety of materials in emergencies such as explosions and fires and prevent unauthorized access.

IV. Revisions and Upgrades

Compared to the old version (GJB2805A-2002), the new version adds "small restricted area" anti-theft measures, requires every door to be equipped with locks, strengthens key management and warehouse alarm device specifications, and incorporates some appendix content into the main text, enhancing the standard's practicality and rigor.

V. Summary

GJB2805B-2021 establishes a systematic anti-theft technical system for ordnance warehouses through specifications on materials, structure, locks, testing, and other aspects, combining explosion resistance, fire resistance, moisture resistance, and other composite functions. It is an important basis for warehouse security construction in the national defense and military industry.
