Ningbo ZRCC Lyondell Chemical Co., Ltd has led the development and successfully launched the international standardISO 25095-1:2026Industrial propylene oxide — Part 1: Determination of purity and trace impurities — Gas chromatographic method. The official publication of this standard fills the long-standing international standard blank in propylene oxide detection technology, marking a major milestone in the global standardization of propylene oxide product inspection and significantly advancing the internationalization of the industry’s standard system.
As a core fundamental chemical raw material, propylene oxide acts as a pivotal industrial bridge connecting upstream propylene raw materials and diverse downstream industrial sectors, including polyurethane manufacturing, fine chemical production, and electronic material processing. The technological and industrial development level of the propylene oxide industry directly governs the quality and innovation capability of multiple terminal application fields. Furthermore, it plays an irreplaceable strategic role in safeguarding the stability of the national chemical industrial chain and enhancing core national industrial competitiveness in the global market.
The newly released ISO 25095-1:2026 establishes a unified global measurement benchmark for international propylene oxide trade. It effectively eliminates cross-border technical trade barriers, reduces repeated testing and comprehensive transaction costs for global chemical enterprises, and delivers strong new momentum for Chinese chemical manufacturers to elevate their status and discourse power in the global industrial value chain.
According to the relevant person in charge of Zhenhai District Administration for Market Regulation, the implementation of this international standard will further standardize global propylene oxide production and testing specifications, promote consistent product quality worldwide, and facilitate smoother and more standardized global trade cooperation in the chemical sector.
In recent years, Zhenhai District Administration for Market Regulation has fully implemented the national standardization strategy, building a complete industrial standardization cultivation system centered on policy guidance, demonstration leadership, and precise enterprise support. The local market supervision department has promoted the regional standardization development model from basic industrial support to innovation-driven high-quality development.
To fully unleash the technological and standard-setting potential of leading chemical enterprises including Ningbo ZRCC Lyondell Chemical Co., Ltd, the authority has launched a customized "one enterprise, one file" demand service mechanism. It integrates high-end industry expert resources, provides door-to-door professional guidance for enterprise standard research and development, and builds a professional docking and exchange platform for domestic and international standardization institutions.
Up to now, enterprises in Zhenhai District have led the formulation and revision of 12 international standards, fully demonstrating the region’s strong technological strength and leading position in the global advanced chemical industry standardization field.
