Overview
EN ISO 11111-7:2005/A1:2009 is Amendment 1 to ISO 11111-7:2005 - the part of the ISO 11111 series that sets safety requirements for dyeing and finishing machinery. Published as a CEN draft amendment (prA1) in 2008/2009, this amendment updates normative references, clarifies safety responsibilities and adds explicit guidance for specific hazards found in textile finishing equipment (notably rollers on stenters and continuous ranges).
Key topics and technical requirements
- Updated normative references: many references in Part 7 are replaced with newer editions, e.g.
- Roller hazards (new Clause 5.1.1): specific requirements addressing entanglement, drawing-in, crushing, friction and abrasion from rollers on special finishing machines (e.g., stenters, continuous dyeing ranges). Key points:
- Definition and scope of “roller” (draw, guide, uncurling rollers etc.).
- Risk assessment per ISO 14121-1 (as amended in introduction).
- Where risk assessment shows up to minor/moderate injuries, Sensitive Protective Equipment (SPE) covering the whole width is permitted as an alternative to measures in ISO 11111-1:2009, provided activation and positioning criteria are met (automatic activation by approach and operator-intent activation). Residual risks must be documented in manuals and signposted on the machine.
- Illustrative example: SPE release cord arrangement at a stenter exit (figure referenced in amendment).
- Control system integrity for dangerous elements: for equipment such as jigs, the safety-related control system must meet PL = d (ISO 13849-1:2006) or SIL = 2 (IEC 62061:2005); lower levels only after formal risk assessment per the relevant annexes.
Practical applications and users
This amendment is essential for:
- Machine manufacturers and designers updating designs to current normative references and machine guarding rules.
- Safety and compliance engineers performing risk assessments, specifying SPE arrangements and verifying control-system performance (PL / SIL).
- Maintenance and operational staff who need to understand residual risks, protective device placement and emergency stop/activation behavior.
- Purchasers, notified bodies and regulators checking conformity with up-to-date CEN/ISO requirements for dyeing and finishing equipment.
Related standards (highlighted)

This amendment aligns Part 7 with modern safety-system standards and provides targeted guidance for common, high-risk elements in dyeing and finishing machinery.
