Good News | Ningbo PNC Technology Participates in Drafting the Group Standard "Technical Requirements for High-Temperature-Resistant Cartridges for Industrial Dust Collection"
Recently, the group standard T/CIET 2492‑2026 "Technical Requirements for High-Temperature-Resistant Cartridges for Industrial Dust Collection," issued by the China International Economic and Technical Cooperation Promotion Association, was officially released and simultaneously implemented on May 14, 2026. Ningbo PNC Technology Co., Ltd., as a leading drafting unit, participated throughout the standard-development process, contributing its technical practice and industry experience to promote standardized, high-quality development of the high-temperature dust-collection cartridge industry.
This standard is the first domestic group standard specifically for "self-supporting rigid/semi-rigid high-temperature-resistant cartridges," filling the industry gap in unified technical specifications for high-temperature industrial dust-collection cartridges. It applies to high-temperature cartridges with metal-, ceramic-, polymer- and fiberglass-based or composite substrates, covering operating temperatures of 180°C–300°C. It defines classification/marking, appearance, dimensional tolerances, substrate thermal stability, mechanical and chemical stability, thermal-shock resistance, overall filtration performance, sealing performance, inspection rules, and packaging/transport, with normative appendices specifying stiffness and chemical-corrosion test methods—providing an authoritative unified basis for R&D, manufacturing, inspection and selection.
During the standard-development cycle, PNC's technical team was deeply involved in discussions, test verification, clause justification and manuscript revision. Drawing on years of R&D and project experience in high-temperature filtration elements and industrial dust-collection purification, it provided practical recommendations on key technical points—cartridge thermal shock, sealing performance, stiffness evaluation and high-temperature reliability—offering important practical support for the standard's scientific rigor and engineering applicability.
Being able to participate in industry group-standard development is full recognition by the industry of PNC's technical strength and product-development capability. Participating in standards is both an honor and an industry responsibility. In the future, PNC will continue to deepen R&D in high-temperature dust-collection filtration materials and filtration equipment, rigorously implement this standard's requirements, and drive product iteration through standardization. It will also actively engage in more industry standards, collaborate with upstream and downstream partners, advance technology in high-temperature industrial dust collection, and support industrial flue-gas dust control and the dual-carbon goals.
