ČSN EN ISO 13766-2 This document provides test methods and acceptance criteria for the evaluation of the electromagnetic compatibility (EMC) of earth-moving machinery, as defined in ISO 6165:2012, and of the following building construction machinery as classified in ISO/TR 12603:2010: - drilling and foundation equipment; - equipment used for the preparation, conveyance and compaction of concrete, mortar and processing reinforcement; - road construction and maintenance machinery and equipment. It deals with EMC requirements related to the functional safety of the machinery, its electrical/electronic subassemblies (ESA) and of separate ESA. This document is relevant only to the safety-related parts of control systems (SRP/CS) as defined in ISO 13849-1:2015 using electrical/electronic components which meet design requirements equal to or greater than safety related performance level PL b as defined in ISO 13849-1:2015. It also deals with electrical and electronic components or separate ESA intended to be fitted on machinery under the restriction of PL b. The following electromagnetic disturbance phenomena are evaluated: - radiated electromagnetic fields from off-board sources with various field strengths and frequencies; - radiated electromagnetic fields from on-board sources (antenna inside/outside) with various field strengths and frequencies; - electrostatic discharge; - conducted and coupled electrical transients. The machinery can have DC or AC or a combination of both as the internal electrical power supply system. This document is not applicable to machines that are designed to be supplied by an external mains network or to phenomena caused by military applications. NOTE: Grid-connected machines are covered by IEC 61000.
