Accessible parts of equipment with standard IEC 62368 General An accessible part of an equipment is a part that can be touched by a body part. For the purposes of dctermining an accessible part, a body part is represented by one or more of the specified test probes. Accessible parts of an equipment can include parts behind a door, panel, removable cover, etc. that can be opened without the use of a tool. Accessible parts do not include those that become accessible when floor standing equipment having a mass exceeding 40 kg is tilted. For equipment intended for building-in or rack-mounting, or for subassemblies and the like for incorporation in larger equipment,accessible parts do not include those that are not accessible when the equipment or subassembly is installed according to the method of mounting or installation specified in the installation instructions. A part is considered accessible if the instructions or markings intended to be followed require that a person phys

The flame test is one of the commonly used methods to evaluate the fire danger of electrical and electronic products. GB/T 5169.5-2020 “Test Fire Five – Test Flame Needle Flame Test Method Equipment, Confirm Test Method and Guide” as the latest version of the standard, after four revisions, clearly defines the purpose of the test is to determine that under the specified conditions, the test flame will not cause the component to ignite, or the test flame ignites the combustible component, but the burning time or burning length of the component is limited, and the flame or The burning or hot particles falling from the sample will not spread the combustion. The test flame applied to the sample simulates the flame that may be generated from the components near the sample in actual application, such as the flame generated due to electrical failure. The standard continuously refines and improves the requirements in terms of test conditions, test methods, test equipment, and calibration stan
