Safety Verification and Validation
- The Machinery Directive requires that all machinery supplied meets the Essential Health and Safety Requirements and to be safe.
- The Use of Work Equipment Directive (RD 1215/97) requires that the workers work equipment meet the Minimum Health and Safety Requirements and to be safe.
- Safety Verification and Validation includes a check of all machine documentation, a verification of the elements and characteristics of each of the Safety Functions, etc.
Safety Verification in Machinery Reception
- Although all machines placed on the European market must comply with applicable legislation regarding machine safety, the end user has a responsibility to ensure the safety of the machines in his possession.
- The newly purchased machine is analysed, checking that it complies with the applicable directives and analysing whether there are any risks not covered by the manufacturer.
Functional Safeyty Validation ISO 13849-1 or EN 62061
- Safety-related control systems must now be based on the concept of Safety Functions in accordance with the harmonised standards ISO 13849-1, ISO 13849-2 or EN 62061.
- A Validation is performed to ensure that the installed safety elements are correctly selected and wired on the machine, determining whether the PL and PFHd values of the circuits are suitable for the application.
Measurement of Safety Function Response Time
- All safety elements must be placed at a distance to ensure that the dangerous elements are not dangerous when the operator reaches them.
- The safety distance depends directly on the stopping time of the dangerous elements.
- The response and stopping time of dangerous machine movements is measured on site and the safety distance at which the protective elements must be positioned is determined in accordance with the harmonised standard ISO 13855.
