Introduction

Interpretation of the core content of the standard

This standard specifies the safety technical requirements for coal industry analyzers in measuring the moisture, ash and volatile matter of coal and coke, and is applicable to laboratory environments with a rated voltage not exceeding 600V.

Key indicators of electrical safety

Protection type	Electrical clearance (mm)	Creep distance (mm)	Test voltage (AC)
Basic insulation	≥0.2	≥1.0	1500V
Double insulation	≥0.4	≥2.0	3000V

Note: The minimum electrical clearance under pollution degree 2 is 0.2mm, and high-voltage components must pass the 1.2/50μs pulse voltage test.

Mechanical safety design requirements

Protection of moving parts must meet the following requirements:

Rotating parts should be equipped with protective covers with an opening size of ≤12mm
Equipment with a mass of ≥18kg must be equipped with a special handling device
Static pressure bearing capacity of the shell is 30N, and dynamic impact energy is 5J

Fire prevention and temperature control

Key fire prevention measures:

Non-metallic shell materials must meet the flame retardant grade of GB/T 11020 FV-1
Microwave leakage ≤50W/m² (50mm from the surface)
Touchable surface temperature ≤70℃ (metal)/80℃ (non-metal)
