NB/SH/T 0969-2018 in English

The industry standard "Determination of Diene Value in Petroleum Products - Maleic Anhydride Addition Reaction Method" is designated as NB/SH/T 0969-2018. This standard was issued on October 29, 2018, and came into effect on March 1, 2019. It provides a method for determining the diene value in petroleum products using the maleic anhydride addition reaction.

The diene value is a critical parameter in assessing the quality and stability of petroleum products, particularly those containing conjugated dienes. The maleic anhydride addition reaction method outlined in this standard is a widely recognized technique for accurately measuring the diene value. This method involves the reaction of maleic anhydride with the conjugated dienes present in the sample, followed by titration to determine the extent of the reaction.

This standard is essential for industries involved in the production, refining, and quality control of petroleum products. It ensures consistency and reliability in the measurement of diene values, which is crucial for maintaining the performance and safety of these products. The NB/SH/T 0969-2018 standard is a valuable resource for laboratories and professionals working in the petroleum industry, providing a clear and standardized approach to diene value determination.
