Introduction

In-depth interpretation of GB/T 32812-2016 standard

Standard Dimensions	Content Overview	Comparative Analysis
Scope and Applicability	Applicable to the limit requirements and determination methods of banned substances in metalworking fluids.	Compared with international standards, GB/T 32812-2016 pays more attention to the special testing requirements of water-based metalworking fluids.
List of banned substances	Including harmful substances such as nitrite and nonylphenol polyoxyethylene ether, with clear limit requirements.	Added a number of determination methods for banned substances to fill the gap in domestic standards.
Determination method	Advanced detection technologies such as liquid chromatography and gas chromatography are used.	Some methods are in line with international standards, but more localized optimization is used in complex sample processing.

Background and significance of standard implementation

With the enhancement of environmental awareness, the impact of harmful substances in metalworking fluids on human health and the environment has attracted much attention. The formulation of GB/T 32812-2016 fills the gap in this field in China and provides an important basis for standardized production in the industry.

Detailed explanation of the determination method of banned substances

Nitrite determination:Ion chromatography is used, which is suitable for the detection of water-based metalworking fluids. This method has high sensitivity and is easy to operate.

Determination of nonylphenol polyoxyethylene ether:Liquid chromatography, quantification by external standard method to ensure accurate and reliable test results.
