Overview

EN ISO 8230-2:2008 - Safety requirements for dry-cleaning machines, Part 2: Machines using perchloroethylene (perc) is a CEN-adopted ISO standard that specifies safety requirements for dry‑cleaning machines that exclusively use perchloroethylene (perc). Taken together with ISO 8230-1:2008 (common requirements), this type-C standard addresses significant hazards specific to perc use - vapour inhalation, skin and eye contact, and environmental contamination (groundwater and sewer). It applies to machines used as intended and under reasonably foreseeable misuse, and to machines manufactured after the standard’s issue.

Key topics and technical requirements

• Scope & machine types: Applicable only to closed‑circuit machines using perc; excludes open‑circuit and transfer machines.
• Integration with ISO 8230-1: Machines must meet Part 1 requirements unless modified or completed by Part 2.
• Ventilation interlock: Provision for interlocking machine operation with general room ventilation; guidance must appear in the instruction handbook.
• Water separator and drainage:
  • Separator outlet must discharge into a sealed collecting system (e.g., decantation tank or purifier) to prevent perc loss.
  • Collecting tank must be detectable (e.g., sight glass), labelled as containing perc, and sized at least for the maximum one‑day production.
  • Drainage must be via a manual valve that closes automatically when released or by direct return to the still/reservoir.
• Distilling installation safeguards:
  • Pressure‑relief device on the still that vents excess pressure; its operation must cut off still heating and be inspectable.
  • Still heating-surface temperature limit: ≤ 150 °C.
  • Coolant interlock to stop heating if coolant flow drops and to trigger visual/acoustic alarm; solvent condensate temperature must not exceed 55 °C.
  • Manual drain valves must return to closed when released and only be opened below 40 °C.
• Verification & testing: Verification methods include design review, inspection, measurement and testing as specified in the standard (see verification table).
• Information for use: Specific requirements for labels, signals and the instruction handbook (including precautions for maintenance and spill prevention).

Applications

• Ensures safe design, manufacture and operation of commercial and industrial perc dry‑cleaning machines.
• Supports product conformity with European Machinery Directives (see informative Annex ZA/ZB), aiding CE marking and regulatory compliance.
• Reduces operator exposure, workplace emissions, and environmental contamination during operation, maintenance and distillation.

Who should use this standard

• Machine designers and manufacturers
• Safety and compliance engineers
• Technical authors (instruction handbooks)
• Service technicians and maintenance managers
• Regulatory bodies and conformity assessors
