CE-Conformity Assessment Procedure
Systematic evaluation of your machine to ensure compliance with all relevant standards.
Run-Down Time Measurement
Precise determination of the run-down times and stopping distances of your machines — as the basis for correctly dimensioned safety distances and maximum occupational safety.
Why Run-Down Time Measurement?
Determine Safety Distances Correctly:
Only with real run-down values can the safety distances for light curtains, fences, and doors be determined correctly and reproducibly.
Legally Compliant Documentation:
Measurement protocols provide verifiable evidence for audits, authorities, and insurance companies.
This supports a legally compliant CE evaluation.
Detect Wear Early to Avoid Downtime:
Optimized protective measures improve machine safety while maintaining productivity and reducing false shutdowns.
What for & When Required?
- New machines or extensively modified systems
- Initial and recurring inspections according to the Operational Safety Ordinance (BetrSichV) for safety-related functions
- Integration and adjustment of light curtains, interlocks, two-hand controls, setup mode, and emergency stop devices
- Early detection of wear and aging (e.g., brakes), which can lead to hazardous increases in stopping distance
- Evidence for audits, professional associations, insurers, and market surveillance authorities
Standards and Fundamentals
- EN ISO 13855 — Positioning of safeguards with respect to approach speeds
- EN ISO 13849-1 — Safety-related parts of control systems (design and verification of functional safety)
- DIN EN ISO 13857 — Safety distances to prevent reaching hazardous areas
- EN 60204-1 — Electrical equipment of machines
We translate standard requirements into concrete, measurable criteria.
Note:
Changes to drives or control systems can influence safety distances — measurements should therefore be repeated after modifications.Measurement – Step by Step
Definition of Measurement Points
Determination of relevant movement types and switching points (e.g., safety light curtain or two-hand control).
Measurement Under Operating Conditions
