ESPE and Machine Downtime Measurement (EST)
Benefits:
To determine the machine's stopping time, we perform position calculation and verification of safety devices that prevent access to moving parts of machines under EN ISO 13855 and meet the requirements of the Use of Work Equipment Directive, all on your behalf.
Description:
Step-by-step compliance with machinery safety directives and standards
We offer two supporting services to further help you meet your legal obligations:
- Machine Stopping Time Test
- ESPE Device Position Calculation and Verification in accordance with EN ISO 13855
This test is a critical process for machine design, installation, commissioning, and maintenance. It is particularly important for our country, where the Use of Work Equipment Directive and the Machinery Safety Directive, which mandate these tests, are applied.
Therefore, if you use ESPE devices, the functionality and positioning of these devices must be formally tested and approved for compliance at regular intervals by an "authorized" person. This includes safety devices such as light curtains, laser scanners, single-beam light sensors, pressure mats, and interlocks covered under EN ISO 13855.
In our country, the majority of users employing devices under this standard are unaware of this requirement. End users do not formally test their ESPE devices or record the results. Consequently, they expose their employees to potential risks.
As a best practice, the following test intervals are recommended for ESPE devices:
- Type 2 devices: every 12 months
- Type 4 devices: every 6 months.
The assessment provides:
- Identification of each safety function related to a suitable device on the machine or assembly
- Physical testing of the machine or assembly's stopping time in comparison with the identified safety functions
- Position calculation of devices such as light curtains, laser scanners, and single-beam light sensors in relation to the hazard under EN ISO 13855.
