GSO ISO 28721-5:2021 搪瓷和搪瓷 过程工厂的搪玻璃设备 第5部分：缺陷的表示和表征

ISO 28721-5:2016 establishes a system for the cataloguing of defects in enamellings for chemical service and vessels. In addition, it describes some types of areas in which defects have been treated and which can easily be confounded with enamelling defects. It serves for a consistent language use concerning the designation and characterization of enamelling defects. ISO 28721-5:2016 is limited to detectable defects and does not purport to fully take into consideration all occurring types of defects. It does not evaluate enamelling defects; the classification carried out is based on experience and corresponds, as far as possible, to ISO 28721-1. NOTE Regarding the acceptance of glass lined equipment for use in process engineering, ISO 28721-1 applies.
