PD CEN/TS 927-9 specifies a method for assessing the resistance of a coating system on wet wood to separation from the substrate by measuring the force necessary to detach or rupture the coating system by a normal tensile strain applied through an attached stud (dolly)

Processing industries

The calculation procedures of this standard also apply to the determination of the thermal class of an electrical insulation system when the thermal stress is the prevailing ageing factor

Essentially the same measurement techniques are used in the diagnosis of structure-borne sound using "transfer path analysis" (TPA)

Mechanical vibration. Rotor balancing - Procedures for assessing balance errors Ingestion-build-239834 PD CEN/TS 927-9 specifies a1 Scope This part of ISO 21940 specifies the requirements for the following: a) identifying errors in the unbalance measuring process of a rotor; b) assessing the identified errors; c) taking the errors into account. This part of ISO 21940 specifies balance acceptance criteria, in terms of residual unbalance, for both directly after balancing and for a subsequent check of the balance quality by the user. For the main typical errors, this part of ISO
