Emergency stop and safety interlock test

The proof test interval comes from the SIL or PL calculation and changing it changes the safety case. Log the controller diagnostics as evidence between tests; do not touch the interval.

What does an emergency stop and safety interlock test involve?

Emergency stop and safety interlock test checks: stop category achieved, stopping time, interlock demand and response logged, fault log clear. Observed by functional test with a stopwatch or stopping-time meter; safety PLC diagnostics log. Proof testing of safety functions at the interval determined by the risk assessment is required under machinery safety law (the Provision and Use of Work Equipment Regulations, the Machinery Directive, ISO 13849 and IEC 62061); the interval is calculated, not chosen.

Condition that replaces the interval
None that replaces the interval. The safety function proof test is set by the safety integrity level calculation and must be performed; the safety controller logs demands and faults continuously as supplementary evidence.
Reading that proves it
Stop category achieved, stopping time, interlock demand and response logged, fault log clear
Why the interval stays
Proof testing of safety functions at the interval determined by the risk assessment is required under machinery safety law (the Provision and Use of Work Equipment Regulations, the Machinery Directive, ISO 13849 and IEC 62061); the interval is calculated, not chosen.
