The brief procedure of how to get a gas mixture of low concentration and high accuracy with the double balance weighing method was described. This method requires two balances of both different ranges and high resolutions, also tow sets of equipment for introducing Ar, Ne, Kr, Xe, and the Nitrogen for balance gas. Two sets of equipment were fulfilled according to the described procedure without any backflow of the component gases. The residual gas in the filling equipment was analyzed to correct the mass of the component gases filled into the mixture gas. By this way, the concentration of Kr and Xe in the preparing mixture gas, is about 0.1%, with the maximum uncertainty of about 0.1%.

Established in 1997, the European New Car Assessment Programme （Euro NCAP） provides consumers with a safety performance assessment for the majority of the most popular cars in Europe. Thanks to its rigorous crash tests, Euro NCAP has rapidly become an important driver safety improvement to new cars. After ten years of rating vehicles, Euro NCAP felt that a change was necessary to stay in tune with rapidly emerging driver assistance and crash avoidance systems and to respond to shifting priorities in road safety. A new overall rating system was introduced that combines the most important aspects of vehicle safety under a single star rating. The overall rating system has allowed Euro NCAP to continue to push for better fitment and higher performance for vehicles sold on the European market. In the coming years, the safety rating is expected to play an important role in the support of the roll-out of highly automated vehicles.
