Introduction

Core changes in the standard revision

Revision content	2008 edition	2022 edition
Test scope	Limited to aluminum alloy	Extended to aluminum and aluminum alloy
Definition of terms	12 terms	Simplified to core terms such as measurement accuracy
Equipment requirements	No clear stability requirements	Added 30-minute stability indicator (±0.2MS/m)

Key technical requirements

Test equipment specifications

Standard requirements for eddy current conductivity meters:

Frequency range50kHz-500kHz (60kHz recommended)
Test accuracy±0.2MS/m
Lift-off suppression≤0.2MS/m

Typical equipment: SitestD2.069, SiscopeSMP350 conductivity meters

Comparison of test methods

Project	Contact	Non-contact
Applicable scenarios	Precise measurement in the laboratory	Quick detection on the production line
Test accuracy	±0.2MS/m	±0.3MS/m
Special requirements	Surface cleaning required	Motion control device required

Implementation suggestions

Periodically check the equipment (every 6 months for contact type and every 3 months for non-contact type)
For curved surface testing, the correction coefficient table provided in Appendix D is preferred
For thin plate testing, it is recommended to use a 480kHz high-frequency probe
