SIST EN 175:1998

Overview

SIST EN 175:1998 – Personal Protection: Equipment for Eye and Face Protection During Welding and Allied Processes is a European standard that specifies the essential safety requirements and test methods for personal protective equipment (PPE) designed to shield the eyes and face during welding, cutting, and similar operations. Developed by the Slovenski inštitut za standardizacijo (SIST), this standard outlines the protection needed against a range of hazards such as harmful optical radiation, mechanical injury, electrical risks, and flammable exposures.

This standard is fundamental for manufacturers, employers, and users who seek compliant and effective eye and face PPE for welding and related activities. It ensures both the safety and ergonomic considerations for the operator, while referencing other key PPE standards including EN 166 (general eye protection requirements), EN 169 (welding filters), and EN 379 (automatic welding filters).

Key Topics

• Scope of Protection: Defines PPE for guarding against optical, mechanical, flammable, and electrical hazards encountered in welding and allied processes.
• Performance Requirements: Specifies criteria for the materials, design, and manufacture of protective filters and equipment to ensure safety and comfort.
• Test Methods: Outlines procedures for verifying protective capabilities according to standardized methods.
• Ergonomic Considerations: Addresses the fit, comfort, and usability of PPE, ensuring that it can be worn safely throughout operations.
• Compatibility: Establishes the necessity for PPE to accommodate protective filters (with or without supplementary oculars), in accordance with EN 166, EN 169, and EN 379.
• Exclusions: Clarifies that this standard does not cover hoods, inspector face screens, laser protection, or PPE designed for special welding applications.

Applications

SIST EN 175:1998 is widely applicable across industries where welding, cutting, brazing, and soldering are common. Key sectors and professionals who should consult this standard include:

• Welders and Fabricators: Ensures selection of appropriate eye and face PPE compliant with European requirements for industrial safety.
• Manufacturers of Welding PPE: Provides guidelines for designing, testing, and certifying equipment for the European market.
• Safety Managers and Inspectors: Assists in developing safety protocols and auditing workplace compliance for personal protective equipment.
• Training Providers: Serves as a reference for curriculum on safe welding practices and PPE selection.

The standard's requirements help minimize risks from common hazards such as ultraviolet (UV) and infrared (IR) radiation, flying particles, and accidental electric contact, enhancing workplace safety and operator confidence.

Related Standards

For comprehensive eye and face protection, the following standards are referenced or closely related to SIST EN 175:1998:

• EN 166:1995 - General requirements for eye protection
• EN 169:1992 - Specifications for welding filters
• EN 379:1994 - Requirements for automatic welding filters
• EN 207 / EN 208 - Protection against laser radiation (not covered by EN 175)
• EN 812 / EN 397 - Head protection standards for related safety gear

These standards together create a robust framework for ensuring personal protection in welding and similar hazardous environments.

By adhering to SIST EN 175:1998, organizations can maintain high levels of safety, comply with European Union regulations, and provide welders and operators with reliable protections against the most significant risks encountered during welding and allied processes.
