The Thai Industrial Standards (TIS) is a technical requirement that the Thai Industrial Standards Institute (TISI) has established as a manufacturing guideline in order to undertake standardization and aim for products with optimal quality. Contents of the TIS include technical specifications, product characteristics, product operating performance, quality of raw material and testing procedures. Currently there are over 2,000 standards covering numerous consumer products such as food, electrical appliances, vehicles, construction material and many more.
An intermix rate of 20% minimun by weight is recommended for optimum reflectivity and durability.
