Introduction

With the development of all aspects of my country's economy and society, various types of water leisure and work activities have become very frequent and common: due to various waters the environment and the surrounding environment are very different, and the risk of their activities is also very different, so the requirements for safety facilities are also very different: Current country There is no unified standard for this in China, and there is a lot of arbitrariness: Various types of life-saving equipment are also uneven, and there is an urgent need for unified standards:

Implement regulations and guidance to better protect the safety of life and property of the broad masses of the people: Therefore, in accordance with advanced international conventions and norms, it is very necessary and urgent to finalize this document: GB/T 32234 aims to establish the safety requirements and test methods for personal buoyancy equipment: It is planned to be composed of 10 Partial composition:
