Introduction

Interpretation of the core content of the standard

Corpse freezer is a key equipment in the funeral industry, and its technical specifications directly affect the quality of body preservation. This standard establishes a complete technical system from three dimensions: temperature control, structural design, and material performance.

Comparison of key technical indicators

Project	Requirements	Test conditions
Freezing temperature	-18℃～0℃	Ambient temperature 32℃
Cooling speed	≤3 hours to reach -18℃	No-load start
Temperature fluctuation	≤4℃	Stable operating state
Working noise	≤55dB(A)	Measured at a distance of 1m

Key points of structural design

The standard particularly emphasizes that the body shelf must meet the 150kg load-bearing requirement without deformation, and the door hinge must pass the 100,000 opening and closing test. In actual applications, a funeral home in Hangzhou once had an accident where a body slipped due to shelf deformation, highlighting the importance of structural strength.

Refrigeration system requirements

The enhanced refrigeration standard, which is different from that of household refrigerators, is adopted:

Working time coefficient ≤60%
Annual refrigerant leakage ≤0.5g
Three-phase 380V power supply support

A case in which a certain brand of equipment crashed due to the continuous operation of the compressor confirmed the necessity of limiting the working time coefficient.

Implementation suggestions

1. Check the consistency of the nameplate information with the standard clause 8.1 when purchasing
2. Regularly test the door seal airtightness (standard clause 6.4.2)
3. Establish a temperature log to monitor the fluctuation range
