Validation of safety-related wireless machine control systems (NT TR 605)

NT TR 605

  • Wireless technologies are spreading also to safety-related applications. Wireless communication is realised by sending messages bit by bit from transmitter to receiver (serial mode communication). This resembles quite much the method used in field buses. There are already several field buses, which are validated to be used in safetyrelated applications.

Machinery and equipment: Declared noise emission values based on the determination of the combined standard deviation (NT ACOU 100)


  • This Nordtest method provides quidelines for determining the A-weighted declared single-number and dual-number noise emission values of machinery and equipment based on the determination of their spectrum or A- and C-weighted noise levels.


Nordtest is a trademark of Nordic cooperation in conformity assessment. The emphasis of Nordtest is to develop, promote and innovate Nordic test methods and pre-normative activity. Nordtest endeavours to remove technical barriers to trade and promotes the concept: “Approved once, accepted everywhere”.
