EN ISO 8230-3:2008 PDF

Overview

EN ISO 8230-3:2008 - “Safety requirements for dry-cleaning machines - Part 3: Machines using combustible solvents” is a CEN-adopted ISO type‑C standard that specifies safety requirements for dry‑cleaning machines using combustible solvents (CS). Applied together with ISO 8230-1:2008 (common safety requirements), this part focuses on hazards specific to combustible-solvent machines and sets manufacturer responsibilities for design and risk reduction under intended use and reasonably foreseeable misuse.

Key topics and technical requirements

• Scope and structure
  • Applies to machines using CS as defined in ISO 8230-1 and to machines manufactured after the date of issue.
  • Complements ISO 8230-1 and is part of the ISO 8230 series (Parts 1, 2, 3).
• Explosion protection and monitoring
  • Requires measures to prevent explosive atmospheres and mitigate explosion risk (concepts such as LEL, LEP, LOC are defined).
  • Control systems related to explosion protection must be redundant or automatically checked; failures must be detected and cause automatic machine shutdown.
  • Malfunctions in explosion protection must be indicated visually and acoustically.
• Electrical safety
  • Electrical equipment must comply with relevant electrical safety standards (e.g., IEC 60204-1).
  • Conductive components must be bonded; wiring must not be routed where solvent vapors can collect.
• Solvent emission and distillation hazards
  • Specific requirements cover combustible solvent emissions during washing, drying and in distilling equipment.
  • Measurement and detection systems for oxygen and CS concentrations must be provided and automatically checked each cycle.
  • Instruments referenced include EN 50104 (oxygen measurement) and EN 61779 series (flammable gas detection).
• Referenced standards and test methods
  • Normative references include ISO 2719 (flash point), ISO 12100-1 (basic safety concepts), IEC/EN standards for explosive atmospheres and measurement equipment (EN 60079-0, EN 13463-1, etc.).

Applications and users

• Primary users
  • Dry-cleaning machine designers, manufacturers and integrators who build machines that use combustible solvents.
  • Safety engineers, conformity assessors and test laboratories verifying compliance with EU Machinery Directives (see Annex ZA/ZB).
  • Facility managers and maintenance teams operating laundries and industrial dry‑cleaning plants using combustible solvents.
• Practical benefits
  • Provides a presumption of conformity with essential requirements of Machinery Directives when applied, helping with CE marking and regulatory compliance.
  • Reduces risk of fire, explosion and solvent exposure through design, detection, and control-system requirements.
