Scope

This Part of GB/T 14571 specifies principle, reagents or materials, instruments
and devices, samples, test procedures, test data processing, precision, quality
assurance and control, test report of gas chromatography for determination of
purity and impurities in ethylene glycol for industrial use.
This Part is applicable to determine the ethylene glycol sample for industrial use
of which purity is not less than 98.0% (mass fraction). Where, the detection limit
of 1,2-propanediol and triethylene glycol is 0.0020% (mass fraction). The
detection limit of 1,3-dioxane-2-methanol, diethylene glycol, 1,2-butanediol,
1,4-butanediol, 1,2-hexanediol and ethylene carbonate is 0.0010% (mass
fraction).
