SIST EN ISO 13766-2:2018 PDF

Overview

EN ISO 13766-2:2018 - "Earth‑moving and building construction machinery - Electromagnetic compatibility (EMC) of machines with internal electrical power supply - Part 2: Additional EMC requirements for functional safety" - specifies test methods and acceptance criteria for assessing electromagnetic compatibility (EMC) as it affects functional safety of earth‑moving and selected building construction machinery. The standard applies to machines with an internal DC and/or AC power supply and focuses on safety‑related parts of control systems (SRP/CS) using electrical/electronic components at or above performance level PL b (ISO 13849‑1:2015). It is published by CEN/ISO and provides practical EMC guidance for manufacturers, test labs and safety engineers.

Key Topics

• Scope and machine types: Earth‑moving machinery (ISO 6165:2012) and building construction equipment such as drilling/foundation machines, concrete preparation/conveyance/compaction equipment, and road construction/maintenance machinery (ISO/TR 12603:2010).
• Functional safety focus: EMC requirements that specifically address safety‑related control functions and electrical/electronic subassemblies (ESA).
• EMC phenomena evaluated:
  • Radiated electromagnetic fields from off‑board sources
  • Radiated fields from on‑board sources (internal/external antennas)
  • Electrostatic discharge (ESD)
  • Conducted and coupled electrical transients on supply and signal lines
• Performance criteria and testing:
  • Immunity tests and acceptance criteria for complete machines and safety‑relevant ESAs
  • Test reporting requirements and indicative test methods
• Limitations: Not applicable to machines designed for external mains supply or military applications. Grid‑connected machines are covered by IEC 61000.

Applications

Who uses this standard and why:

• Machine manufacturers - to design and validate EMC measures for safety‑critical control systems and to support conformity with EU machinery requirements.
• Safety and compliance engineers - to define EMC test plans, evaluate SRP/CS robustness and create test reports.
• Test laboratories - to perform standardized immunity testing on complete machines and separate ESAs.
• Maintenance and service providers - to understand installation and maintenance considerations that affect EMC and functional safety. Practical uses include EMC risk assessment for control systems, pre‑compliance testing of ESAs, and documenting evidence for regulatory conformity under machinery directives.
