Introduction

Interpretation of the core standards for inspection and testing of fireworks and firecrackers

Technical specifications of instruments and equipment

The detection system integrates 28 types of special equipment such as temperature controlled oven, vibration meter, etc.:

Equipment type	Technical parameters	Importance
Drop test stand	Effective height≥12m	★ ★ ★ ★
Electronic balance	Accuracy0.0001g	★ ★ ★ ★ ★

Key test process example

[Thermal stability verification] The temperature fluctuation should be ≤2.5℃ per minute. During the test at 75℃ for 48 hours, in 2019, fireworks from a certain factory that exceeded the standard exploded at 63℃, verifying the importance of this parameter.

Technology evolution background analysis

The new version of the standard is mainly enhanced compared with the previous version:

▸ The accuracy of the test dose of friction products is improved by 100 times
▸ New requirements for PM2.5 particle monitoring
▸ Remote control drop device replaces manual operation
