scope:

This Standard establishes methods for verifying manufacturer's claims for principle battery performance in different use models for various types of internally powered architectural hardware. This Standard applies to both commercial and residential products.

Examples of internally powered architectural devices include motorized deadbolts, hotel locks, input devices, self-contained RFID locks, push button locks, cabinet locks, e-cylinders, portable locks, electric strikes, exit devices, mortise locks, rim locks, bored locks, active RF key fobs, and safe locks

This Standard applies specifically to battery performance claims and does not imply compliance to additional applicable ANSI/BHMA A156 Series Performance Standards

Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance and environmental conditions.

Battery Life Claim Qualifications. It is optional for a manufacturer to communicate that a product is A156.33 certified. A manufacturer can communicate that a product is A156.33 certified without a specific claim. However, if a manufacturer chooses to communicate that the product is BHMA A156.33 certified with a specific claim, the manufacturer shall indicate the Communication, Credential, and Use Case as declared in the certification of their battery life claim in months.
