Main coverage risks and testing items

1.  Six major safety risks: electric shock, energy hazard, fire, mechanical hazard, overheating, radiation.

2. Core tests: withstand voltage, leakage current, grounding impedance, temperature rise, abnormal operation, mechanical strength, fire prevention, moisture/dust prevention, impact, stability

Main coverage risks and testing items:

1.  Electric shock risk: Contact shock from insulation failure, poor grounding or exposed live parts;

2. Fire risk: Ignition from overload, short circuit, arc, overheating or insulation aging;

3. Ground-fault risk: Leakage and equipment damage from failed bonding or equipotential imbalance;

4. Overvoltage/surge risk: Equipment breakdown and safety incidents from lightning or grid fluctuations;

5. Mechanical & environmental risk: Wiring damage, insufficient moisture/dust protection, failure in extreme climates (low temperature/corrosion)。

Main coverage risks and testing items:

1. Insulation & dielectric test

2.  Bonding continuity test

3. Temperature rise test

4. Short-circuit & overload protection

5. Clearance & creepage distance

6. Mechanical strength & durability

7.  Leakage current test

8. Marking & documentation

Main coverage risks and testing items:

1.Verification of terminology, product classification and service environmental conditions

2.General requirements for electrical clearance, creepage distance and insulation construction

3.Dielectric voltage withstand test, bonding/grounding continuity, leakage current test

4.Temperature rise test, safety evaluation under normal and abnormal operation

5.Material flame retardancy, enclosure mechanical strength, ingress protection requirements

6.Compliance review of nameplate, electrical ratings, warning labels and certification marking rules

Main coverage risks and testing items:

• Electric shock prevention (core): Risk of contact shock from energized enclosures due to insulation failure;
• Ground-fault fire: Overheating/arc fire from poor bonding connections;
• Equipotential imbalance: Leakage and interference from potential differences between metal partsCSA Group.
