EU EN series standards, US ANSI series standards, and Japanese JIS series standards, supplemented by general standards issued by the International Organization for Standardization (ISO).

(1) EU EN Series Standards (Core Standards)

• EN 1906: Classification, requirements and test methods for door and window hardware
• EN 12209: Corrosion test method (salt spray) for door and window hardware
• EN 1627: Burglary resistance standard for doors and windows
• EN 13126: Safety requirements for building glass hardware
• EN 14411: Performance requirements for construction fasteners

• EN 1906: Operating cycle life ≥ 100,000 times for high-end door/window hardware; ≥ 50,000 times for standard hardware.
• EN 12209: High-end hardware must pass ≥ 1,000 hours of salt spray testing with no visible corrosion.
• EN 1627: Defines six burglary resistance classes (RC1–RC6). RC2 requires over 30 minutes of prying resistance; RC4 requires over 15 minutes. Most high-end buildings require at least RC2.

(2) US ANSI Series Standards

• ANSI A156.1: Performance requirements for door and window hardware
• ANSI A156.2: Performance requirements for hinges
• ANSI A156.115: Safety standard for smart locks
• ANSI B117.1: Salt spray corrosion test standard

• ANSI A156.1: Operating cycle life ≥ 100,000 times; load capacity must meet architectural application requirements.
• ANSI B117.1: Outdoor building hardware must pass ≥ 500 hours of salt spray testing for outdoor corrosion resistance.
• ANSI A156.115: Strict requirements for anti-theft performance, password security, emergency release, and other functions, serving as the core standard for smart hardware entering the US market.

(3) Japanese JIS Series Standards

• JIS B 1181: Dimensions and performance of bolts and nuts
• JIS H 3100: Copper and copper alloy sheets
• JIS G 4305: Stainless steel sheets
• JIS A 1510: Performance of door and window hardware

• Extremely high dimensional accuracy: e.g., bolt diameter tolerance within ±0.01 mm.
• Strong focus on environmental performance: heavy metal content must comply with Japanese environmental regulations, matching local architectural styles and usage requirements.

(4) ISO General Standards

• ISO 898-1: Performance requirements for high-strength bolts
• ISO 10605: Salt spray corrosion test standard
• ISO 12944: Protective coating standards
