• Tên tiếng Anh / Title in English: Earth-moving and building construction machinery - Electromagnetic compatibility (EMC) of machines with internal electrical power supply - Part 2: Additional EMC requirements for functional safety (ISO 13766-2:2018)
• Phạm vi áp dụng / Scope of standard: ISO 13766-2:2018 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. ISO 13766-2:2018 deals with EMC requirements related to the functional safety of the machinery, its electrical/electronic subassemblies (ESA) and of separate ESA. ISO 13766-2:2018 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. ISO 13766-2:2018 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.
