Introduction

Interpretation of the National Standard of the People's Republic of China GB/T 17529.3—2023

GB/T 17529.3—2023 specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of industrial ethyl acrylate.

Background of standard formulation and analysis of technological evolution

Project dimensions	Old standard (GB/T17529.3—1998)	New standard (GB/T 17529.3—2023)
Scope	Only applies to products made by the esterification reaction of acrylic acid and ethanol.	Extended to industrial ethyl acrylate produced by various production methods.
Quality requirements	Appearance and color indexes are not clearly specified.	Added items such as appearance and color to improve product quality control standards.
Test method	Mainly adopts visual colorimetry.	Added tristimulus colorimetry as an arbitration method to improve detection accuracy.

Standard implementation recommendations

To ensure the effective implementation of the new standard, it is recommended that:

Enterprises should be equipped with professional testing equipment such as gas chromatograph and Karl Fischer moisture meter.
Strengthen employee training, especially the safe operation specifications of hazardous chemicals.
Establish a complete quality traceability system to ensure that the quality of each batch of products can be traced.

Safety Precautions

Industrial ethyl acrylate is flammable, explosive and toxic:

Operators need to wear gas masks and protective glasses.
Storage facilities should be well ventilated and the temperature should be controlled below 30°C.
In case of leakage, evacuate personnel immediately and flush the contaminated area with plenty of water.
