Fire Rated Door Hardware: CE vs UL CertificationIn fire-rated door assemblies, door hardware compliance is not optional—it is a legal, safety, and liability requirement. Using non-certified hardware on a fire-rated door can invalidate the entire fire rating, exposing projects to inspection failure,

Introduction: Why Certification Choice Matters in Door HardwareIn the global door hardware industry, certification is not optional — it is a regulatory and engineering requirement. However, many project teams still ask the same question:Do we need CE, UL, or ANSI/BHMA certification?The answer depends on market location, building codes, fire safety requirements, and project type. Each certification system serves a different purpose, and misunderstanding their roles can lead to project rejection, inspection failure, or legal risk.

UL 10C Fire Test Explained: How Door Hardware Must Perform in Fire-Rated AssembliesIntroduction: Why UL 10C Matters for Fire Door HardwareIn fire-rated door assemblies, door hardware is not an accessory — it is a life-safety component. Hinges, locks, closers, and exit devices must continue to functi

The core distinctions between UL10C and UL10B fire resistance testing lie in the test environment, sealing requirements, scope of application, and certification complexity, as detailed below:1. Test Environment: Atmospheric Pressure vs Positive PressureUL10B: Conducted under atmospheric pressure fir
