Introduction

Analysis of the core content of the standard

This standard replaces WS 310.2-2009. The main technical changes include: adding processing requirements for precision instruments and luminal instruments, adjusting moist heat disinfection parameters, and refining the management of foreign medical devices, etc. 12 important revisions.

Comparison of key operating procedures

Process links	2009 version requirements	2016 version updates
Moist heat disinfection	Temperature ≥ 90℃ Time ≥ 1min	Add A₀ value ≥ 3000 indicator
Pressure steam sterilization	Pressure range is not clear	Precise range of 184.4-229.3kPa is specified
Foreign medical devices	Not separately specified	Add 4.7 special clauses

Special Instrument Handling Specifications

Key Points for Luminal Instrument Operation

For lumen instruments with an inner diameter ≥ 2mm, the standard requires:

A special cleaning brush must be used for lumen treatment (Appendix B.1)
A pressure air gun is used to remove residual water during the drying phase (5.5.3)
Downward exhaust pressure steam sterilization is prohibited (5.8.1.5)

Detailed Explanation of Sterilization Technical Parameters

Key Parameters for Pressure Steam Sterilization:

Sterilizer Type	Temperature	Minimum time	Pressure range
Downward exhaust type	121℃	20-30min	102.8-122.9kPa
Pre-vacuum type	132-134℃	4min	201.7-229.3kPa

Implementation recommendations

Establish a special processing procedure for precision instruments and equip them with protective devices
Regularly verify the A₀ value calculation function of the washer-disinfector
Two-person inspection system is implemented for external medical devices
Hard containers are tested for sealing every month
