Due to environmental protection and changes in oil prices, countries are exploring the use of new fuels such as clean fuels and biofuels. There are many advantages to using CNG and LPG as fuel for automobiles. Because the fuel is cleaner, the engine life is extended, the cost of use is lower, the maintenance cycle is longer, the oil replacement cycle is longer, and the initial modification is more convenient, but the CNG/LPG fuel is used. The system has high working pressure and its related safety standards are relatively high. The fuel system and components are required to be compulsory certification in many countries and regions. The operating vehicles need annual inspection and regular testing is required during operation.

ATIC in-depth research and development in this professional segment, with its global network of authorized and experienced team of experts, has recently provided multi-country certification services to more than ten well-known CNG/LPG fuel system manufacturers, including EU ECE certification and Brazilian INMETRO certification.

Brazil CNG cylinder INMETRO certification
According to the Brazilian INMETRO certification requirements, CNG cylinders need to be tested according to INMETRO Ordinance No. 171, and they can apply for and obtain the INMETRO certificate before they can legally enter the Brazilian market. The certification procedure is as below:
Factory audit
Product data preparation and product testing
Importer audit
Submit technical documentation
Issue a certificate
Registration
The certificate is valid for 3 years, and the confirmation test is required 3 months after the first certification, and the maintenance is performed once every 12 months.
