Specification
EN 397:1995 PROTECTIVE HELMETS FOR INDUSTRY
EN 397:1995 standards for all physical and performance requirements, methods of test and marking requirements for general-use of industrial safety helmets. Performance requirements for the helmet shell are also provided. Mandatory requirements such as shock absorption, resistance to penetration, flame resistance, chin strap anchorages, and label are addressed. Physical requirements for industrial safety helmets including materials and construction, external vertical distance, internal vertical distance, internal vertical clearance, horizontal distance, and wearing height are also included.
EN812: BUMP CAPS FOR INDUSTRY
These are essentially intended for inside use. A bump cap is not intended to protect against the effects of failing objects and must not under any circumstance replace a protective industrial helmet.
EN166: PERSONAL EYE-PROTECTION AGAINST VARIOUS DANGERS
The EN166 standard is applicable to all types of personal eye protection gears used against various dangers liable to damage the eye or to alter the vision, with the exception of radiation of nuclear origin, X rays, laser beams and infrared rays given out by sources at low temperatures. The eye protectors fitted with corrective lenses are not excluded from the application field.
EN169: OCULAR FILTERS FOR WELDING AND RELATED TECHNIQUES
The EN169 standard gives the grade numbers and the transmission specifications of the filters intended to ensure the protection of users carrying out welding, arc gauging and plasma arc cutting works.
EN175: EQUIPMENT FOR EYE AND FACE PROTECTION DURING WELDING AND ALLIED PROCESSES
The EN175 standard specifies the safety requirements and test methods relating to personal protective equipment used to protect the users eyes and face against harmful optical radiation and against other specific risks due to usual welding processes, cutting ones or other related techniques.
EN352-1 MUFFS AND HEADBAND
The section of the standard deals with head fasteners and establishes requirements in terms of manufacture, design and performance, test methods, instructions relating to marking and information intended for users.
EN352-2 PLUGS AND BANDS
This part of the standard also deals with individually moulded ear plugs and devices connected by band, although, it does not deal with the performances of electronic devices likely to be inserted in the ear plugs or on the case of amplitude sensitive plugs.
EN352-3 MUFFS AND HELMET MOUNTED
The present section of the standard stipulates requirements in terms of manufacture, design and performance, test methods, instructions relating to head fastener marking and information intended for head fastener users, when the latter are fixed on protective industrial helmets.
EN 136: OVERALL MASKS
It contains laboratory tests and practical performance tests to check the conformity with resistance to temperature, to impacts, to flame, to thermal radiation, to traction, resistance to cleansers and disinfectants. Furthermore, the visual inspection must concern the marking and the manufacturer information’s guide.
EN 140: HALF MASKS AND QUARTER MASKS
It contains laboratory tests and practical performance tests to check the conformity with resistance to impacts, to cleaners and disinfectants, to temperature, to flame and respiratory resistance.
EN 14387: GAS FILTERS AND COMPOUND FILTERS
EN 143: FILTERS AGAINST PARTICLES
It contains laboratory tests to check the conformity with resistance to impacts, to cleansers and disinfectants, to temperature, to flame and with respiratory resistance.
