EN ISO 23582-1:2023 PDF

Overview

EN ISO 23582-1:2023 - "Plastics and rubber machines - Clamping systems - Part 1: Safety requirements for magnetic clamping systems (ISO 23582-1:2023)" sets out essential safety requirements for the design, construction and machine integration of magnetic clamping systems (MCS) used in plastics and rubber machines (for example, injection moulding and compression moulding machines). It addresses the basic hazards listed in Annex A and gives operational limits and user/integration information to ensure safe use. This is a Type‑C standard (ISO 12100) published and adopted by CEN in 2023.

Key topics and requirements

• Scope and applicability
  • Applies to MCS that use magnetic force to affix moulds to platens; excludes hydraulic, pneumatic or mechanical clamping systems and MCS manufactured before publication.
• Design and construction safety
  • Requirements for magnets and magnetic plates, magnetizing/demagnetizing current handling, and overall MCS force characteristics.
• Control and detection
  • Specifications for the magnetic clamping control system, including detection, magnetizing/demagnetizing actions and interlocks that affect machine movements and enabling.
• Force considerations
  • Safety considerations for magnetic clamping force when MCS is integrated in horizontal and vertical machines (including cantilever effects).
• Electrical and EMC safety
  • Protection against electrical hazards, fault protection, ingress (IP) considerations, and electromagnetic interference.
• Verification, marking and documentation
  • Requirements for verification of safety measures, instructions for integration and use, plus marking and information for safe operation.
• Informative guidance
  • Annex A lists significant hazards; Annex B discusses cantilever effects for half moulds in horizontal machines.

Practical applications and users

Who uses EN ISO 23582-1:2023:

• MCS manufacturers - to design compliant magnetic clamps and control systems.
• Machine builders and integrators - for safe integration of MCS into injection or compression moulding machines.
• Safety engineers & compliance officers - to perform risk assessments and verify conformity.
• Maintenance and service providers - for safe operation, demagnetization procedures and troubleshooting.
• Regulators and market surveillance - to assess conformity and safety documentation.

Typical applications:

• Retrofitting or integrating magnetic clamping systems on injection moulding and compression moulding machines.
• Preparing technical documentation, user instructions and safety validation for MCS-equipped machines.

Related standards

• This Type‑C standard takes precedence when conflicting with generic Type‑A/B machinery safety standards. It is developed in line with ISO/IEC directives and references general safety principles such as ISO 12100. Other process‑specific standards may apply for production hazards (e.g., injection process standards).
