Introduction

Key points of the revision of the standard

Revision dimensions	2003 edition	2021 edition
Scope of application	Basic dosage form	Added 6 new types of preparations, including controlled release preparations
Test conditions	Single 54℃/14d	5-level temperature-time gradient system
Container requirements	General purpose glass bottle	Differentiated container system (including controlled release preparations) class=instrument>explosion-proof constant temperature box, etc.)

Key technological breakthroughs

Innovation in controlled-release preparation testing:For new dosage forms such as long-acting storage bags, the standard clearly states for the first time:

Matrix release preparations must be double-sealed with aluminum foil
Aerosols must use explosion-proof equipment
Direct testing of the original packaging of the product is allowed

Implementation recommendations

Gradient temperature selection principle:When the preparation is used in temperate areas (annual average temperature <20℃), it is recommended to give priority to the 40℃/8-week scheme, which can more accurately simulate the actual storage attenuation.

Special preparation processing: For heat-generating preparations such as electric mosquito coils, the effective ingredient determination must be carried out immediately after cooling to avoid secondary volatilization.

Standard Evolution Analysis

This revision reflects the three major development trends of pesticide preparation technology: 1) popularization of controlled release technology; 2) diversification of dosage forms; 3) refinement of detection scenarios. The deletion of outdated technologies such as pressurized hot storage method reflects the synchronization of standards and industrial development.
