Selecting a testing partner begins with understanding the scope of services available. For electrical instruments and measuring equipment, compliance with IEC 61010 standards is critical to ensure user safety and product functionality. Our laboratory, accredited by CNAS and CMA, offers specialized testing services aligned with IEC 61010 requirements, catering to manufacturers, engineers, and quality managers seeking reliable third-party verification.
Testing Scope
Our IEC 61010 electrical safety testing covers a wide range of products, materials, and grades commonly used in industrial, scientific, and medical environments. Applicable products include multimeters, oscilloscopes, calipers, power supplies, and other measuring instruments. Materials tested include plastics, metals, and circuit board components, with grades varying from standard to high-performance versions. Application scenarios span laboratory research, industrial automation, medical diagnostics, and field measurements. Testing is performed in accordanceance with IEC 61010-1 (General requirements for measuring, checking, and laboratory instruments) and IEC 61010-2x (Specific requirements for particular types of measuring, checking, and laboratory instruments) series, as well as relevant ASTM, ISO, EN, and GB standards where applicable.
Testing Items and Parameters
Testing items include electrical safety hazards such as electric shock, fire hazards, and mechanical damage. Typical parameters and graded limit requirements are outlined in the following table:
| Test Item | Typical Parameters | Graded Limit Requirements |
|---|---|---|
| Input/output voltage withstand test | AC/DC voltage, frequency (50/60Hz), duration (1min/30min) | Failure prevention under rated voltage + 2x rated voltage |
| Creepage and clearance distance measurement | Material group (I, II, III, IV), distance (mm) | Compliance with IEC 60664-1 standards |
| Touch potential test | Open circuit voltage (V), resistance (Ω), current (mA) | < 50V for extraneous voltages, < 0.5V for basic insulation |
| Guard grading test | Resistance (Ω), voltage (V), time constant (μs) | Compliance with IEC 61010-2x specific requirements |
Additional parameters include dielectric strength, Insulation Resistance, and Leakage Current measurements, all performed with calibrated equipment and verified by trained engineers.
Data and Variation Analysis
Parallel-sample and batch-to-batch variation is rigorously assessed through statistical analysis. For parallel samples, relative deviation is calculated as the standard deviation divided by the mean value, expressed as a percentage. Typical acceptance windows for variations are within ±5% for electrical parameters and ±2mm for mechanical measurements, though these may adjust based on equipment sensitivity and client requirements. Batch-to-batch variation is analyzed using control charts and capability indices (Cp, Cpk) to ensure consistency across production runs. All data is reported with confidence intervals and histograms to illustrate distribution patterns, enabling clients to make informed decisions about product reliability and process control.
