Introduction

Interpretation of GB/T 19605—2017 Chlorpyrifos EC Standard

GB/T 19605—2017 Chlorpyrifos EC is an important standard that replaces GB/T 19605—2004. The main technical changes include:

Items	40%	45%
Mass fraction of chlorpyrifos/%	40.0±2.0	45.0±2.3
Mass fraction of phosphorus treatment/%	0.2
Water/%	0.8
pH range	4.5~6.5

The standard stipulates strict test methods, including:

Determination of mass fraction of chlorpyrifos: liquid chromatography (arbitration method) and gas chromatography
Determination of mass fraction of phosphorus treatment: gas chromatography
Determination of moisture: Karl Fischer method
Determination of pH value: GB/T 1601

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

Enterprises should establish a complete quality control system
Sampling and testing should be carried out in strict accordance with the standard
Pay attention to storage and transportation conditions: avoid sunlight and humidity
Safe use: wear protective equipment to prevent contact with skin and inhalation
