Testing Methods
Geometric and dynamic performance is measured with laser interferometers, laser trackers, telescoping ballbars, and high-precision rotary calibrators, providing traceable verification of positioning accuracy, repeatability, and path-following behavior under defined load and speed conditions.
Electromagnetic compatibility testing is performed in semi-anechoic chambers and shielded test rooms equipped with calibrated antennas, ESD simulators, and combination wave generators. Emission levels and immunity thresholds are recorded against the applicable IEC 61000 and IEC 61800-3 limits for industrial environments.
Environmental robustness is evaluated in programmable climatic chambers and on electrodynamic shakers, simulating temperature extremes, humidity cycling, transport vibration, and mechanical shock. Ingress protection testing applies dust and water jet exposure in accordance with IEC 60529 to confirm the declared IP rating.
Functional safety validation combines circuit analysis, fault injection, and hardware-in-the-loop (HIL) simulation to confirm that safety-related control channels behave correctly under both normal and fault conditions. Cybersecurity evaluation applies threat modeling, automated vulnerability scanning, protocol fuzzing, and controlled penetration testing to verify resilience against defined attack vectors. All measurements are supported by documented uncertainty budgets in accordance with ISO/IEC 17025 laboratory practice.

FAQ
What standards govern industrial robot safety testing?
Industrial robots are primarily evaluated against ISO 10218-1 and ISO 10218-2, supplemented by ISO/TS 15066 for collaborative applications and ISO 9283 for performance characteristics. Functional safety of the robot control system is typically assessed per ISO 13849-1 or IEC 62061, while electrical safety follows IEC 60204-1.
Is cybersecurity testing mandatory for smart manufacturing equipment?
Cybersecurity requirements are increasingly written into procurement specifications and regional regulations for connected industrial equipment. Evaluation against the IEC 62443 series — including component requirements (IEC 62443-4-2) and secure development processes (IEC 62443-4-1) — is widely recognized as best practice and is becoming a de facto condition for market acceptance.
What is the difference between Performance Level (PL) and Safety Integrity Level (SIL)?
PL, defined in ISO 13849-1, and SIL, defined in IEC 62061 and IEC 61508, are parallel frameworks for expressing the reliability of safety-related control functions. PL ranges from a to e, while SIL ranges from 1 to 3 for machinery; the appropriate target level is determined during the risk assessment described in ISO 12100.
How long does a typical testing project take?
Timelines vary with equipment complexity and scope. A focused EMC and electrical safety assessment may be completed within a few weeks, while a comprehensive program covering functional safety, performance, environmental, and cybersecurity testing for a large integrated system can extend over several months. Early pre-compliance screening helps shorten the overall schedule.
Which market access schemes can testing support?
Test reports and certificates from accredited third-party laboratories support CE marking under the EU Machinery Regulation, UKCA marking, NRTL certification to UL standards for North America, GB standard compliance for China, and acceptance in markets referencing JIS or EN standards.
Can large production machines be tested on site?
Yes. When equipment cannot be transported to a laboratory, accredited laboratories can perform witness testing and on-site assessments at the manufacturer's facility or final installation site, using portable calibrated instrumentation and documented test procedures to ensure results remain fully traceable.
