1 Scope

This section presents terms and definitions hot surfaces of electrical equipment risk assessment, risk assessment burns, burns threshold, protective measures and Regulations and other documents. This section for AC rated voltage 1000V and below, DC rated voltage 1500V and below the various types of electrical equipment, where possible, Burns body touched the hot surface of the device proposed risk assessment guidance; also proposed under the potential risk of burns cases, take General principles of protection measures, and the selection burns threshold. This section does not apply surface following types of electrical equipment. --- Hot functional surface; --- Adjacent surfaces; --- Joystick control knob (includes a keypad, keyboard, etc.); --- Can not come into contact with the surface. Note. Under normal circumstances, according to the product standards can prevent the risk of burns. If the product is not considered standard in the foreseeable use may come into contact with The surface temperature of the product, or no relevant product standards, the manufacturers need to conduct a risk assessment of their products.
