Abstract
Overview - ISO 3873:1977 (Industrial safety helmets)
ISO 3873:1977 establishes physical and performance requirements, test methods and marking rules for industrial safety helmets intended for general use in industry. The standard sets mandatory tests (shock absorption, penetration resistance, harness performance, flammability) and defines optional performance criteria (low-temperature shock absorption, electrical insulation, lateral rigidity) that apply only where specifically claimed. It also defines headform geometry, conditioning procedures and lab test setups.
