Frequently Asked Questions About TCVN 3769:2016

TCVN 3769:2016 is the Vietnamese national technical standard for Standard Vietnamese Rubber (SVR). It defines quality requirements, classification, testing criteria, and acceptance parameters for SVR grades used in domestic and export markets. The standard helps buyers, manufacturers, and quality-control teams evaluate rubber consistently.
TCVN 3769:2016 covers major SVR grades, including SVR CV60, SVR CV50, SVR L, SVR 3L, SVR 5, SVR 10CV, SVR 10, SVR 20CV, and SVR 20. These grades are classified based on technical properties such as viscosity, impurity limits, color, and other specification criteria depending on the grade.
The SVR technical specification table typically includes key quality indicators such as dirt content, ash content, nitrogen content, volatile matter content, initial plasticity, Plasticity Retention Index (PRI), Lovibond color, Mooney viscosity, and gel content. The applicable parameters depend on the SVR grade being evaluated.
TCVN 3769:2016 refers to recognized testing methods for evaluating SVR quality parameters. These include methods associated with dirt content, ash content, nitrogen content, volatile matter, PRI, Lovibond color, Mooney viscosity, and gel content. The standard aligns technical evaluation with established laboratory testing practices used in the rubber industry.
TCVN 3769:2016 is the national Vietnamese standard specifically used for SVR grades, while TSR is a broader term referring to Technically Specified Rubber systems used in different producing countries. In practice, both serve a similar purpose: defining technical quality requirements for natural rubber grades. However, naming conventions, grade structure, and certain specification details may vary by country or standard system.
