Run-out measurement is used to check the reaction time of a machine stopping when a potentially dangerous situation is triggered – this test is extremely important for equipment that has a long stopping time (run-out) and, as a result, has a negative impact on the safety of workers.

Run-out measurement control is performed primarily for:

  • safety curtains;
  • emergency stops;
  • optical scanners;
  • interlocking guards without locking;
  • pressure mats;


In order to calculate the maximum reaction time. The run-of-the-mill test should be carried out regularly, as through it the actual ability to protect hazardous areas is determined. We would like to point out that each of the measurements carried out by our company is documented and archived, and we use the information contained in Directive 95/63/EC, as well as PN-EN ISO 13855:2010.

Periodic inspections of machine protective equipment

In accordance with the requirements of Directive 2009/104/EC of the European Parliament and of the Council, the employer must periodically inspect the safety equipment of the machine.

When the device is equipped with:

  • optoelectronic safety curtains;
  • two-handed start devices;
  • safety scanners;
  • safety guard stops;
  • other safety components that do not provide physical separation of hazardous areas from the
    operator or bystanders.


It is necessary to measure the stopping time of moving parts of the machine according to the previously mentioned standard PN-EN ISO 13855:2010 – “Safety of machinery – Location of protective equipment in terms of approach speeds of human body parts”.

INEE Industry Sp. z o.o. performs such measurements using a calibrated, specialist Safety Man Delta T device made by HHB. After the measurements, the customer receives a detailed report with the test results – run-out time and minimum safety distance – along with expert analysis and recommendations on the safety system.

The recommended interval between running time measurements is 1 year, but often the machine manufacturer or internal company procedures require more frequent checks.
