Who wrote UN38.3？
The United Nations Committee of Experts on the Transport of Dangerous Goods has prepared United Nations System UN38.3, the version of which is usually updated every two years.

What is the reason for writing UN38.3?
What cameras, phones, laptops, headphones and Tesla cars in life have in common is that they are powered by lithium batteries.
Half a century has passed since the birth of the first lithium ion battery in 1970, and lithium ion batteries are playing an increasingly important role in our lives.

And Tesla Motors, what they have in common is that they are powered by lithium batteries.

Lithium batteries have brought more and more convenience and possibilities to our lives. They have the characteristics of long service life, high energy density, high output voltage, small self-discharge, high charging efficiency, and strong adaptability to high temperatures and ultra-low temperatures. They are widely used in various industries ranging from medical products to consumer electronics, and from industrial finished products to transportation tools.

But just like a coin has two sides, everything has pros and cons, and lithium batteries are no exception. While enjoying outstanding performance, we should also tolerate weaknesses.
The most obvious shortcoming of lithium batteries is their poor safety performance. Sometimes, this attribute can bring harm to people’s daily lives, especially when lithium batteries or lithium battery products are transported by air.

Assuming an accident occurred with the batteries carried by the aircraft, it would be fatal. We know that there will be no danger or danger of fire or explosion when aircraft are flying at high altitude.

To solve this problem, there must be a globally recognized test standard to test these batteries for transportation, so UN38.3 was born.
