Introduction

1. Background and significance of standard formulation

Pesticide density is an important indicator for evaluating the quality and stability of pesticide products. GB/T32776-2016 "Method for Determination of Pesticide Density" is my country's first national standard for pesticide density determination, filling the gap in the industry. The standard was proposed by the China Petroleum and Chemical Industry Federation and is managed by the National Pesticide Standardization Technical Committee.

2. Standard framework and scope of application

This standard is mainly applicable to the density determination of homogeneous liquid pesticides and suspension pesticides, and specifies four methods:

Density meter method (3.1): Applicable to homogeneous liquid pesticides.
Density bottle method (3.2): Applicable to homogeneous liquid pesticides.
Dilution densimeter method (3.3): Applicable to suspension pesticides.
Defoaming density bottle method (3.4): Applicable to suspension pesticides.

3. Comparative Analysis of Standard Methods

Method Name	Scope of Application	Main Features	Precision Requirements
Density Bottle Method	Homogeneous Liquid Pesticides	Easy to operate, fast measurement	Accurate to 0.0005g/mL
Density Bottle Method	Homogeneous Liquid Pesticides	Accurate measurement, suitable for high viscosity samples	Accurate to 0.1mg
Dilution densimeter method	Suspension pesticides	Applicable to low concentration suspensions	Accurate to 0.001g/mL
Defoaming density bottle method	Suspension pesticides	Applicable to samples containing bubbles	Accurate to 0.1mg

4. Practical application case analysis

Application of the density bottle method in the laboratory: A pesticide company used capillary stopper density bottle was used to measure the density of a liquid pesticide. The results showed that the measurement error of this method was less than 0.2%, and it had high accuracy and repeatability.
