As a professional B2B foreign trade supplier of sight glass,we are committed to providing sight glass products that comply with standard specifications. The text helps global buyers quickly understand the core industry standards for sight glass products, ensuring compliance, safety, and efficiency throughout the procurement and usage processes.The following standards are widely recognized in the global industrial sector and serve as the core reference before procurement:
German DIN standard such as DIN 7080、DIN 8902 mainly apply to circular sight glass.It clearly specifies the glass material, thickness, and temperature and pressure resistance grades.DIN 7080 (borosilicate) withstands temperatures up to 280℃, and DIN 8902 (soda-lime) has a temperature limit of approximately 150℃.It’s suitable for conventional operating conditions for industrial pipelines and equipment.
American ASTM standard:ASTM E1963 specifies the heat and impact resistance properties of sight glass.ASTM C1036 specifies clear optical clarity requirements, making it particularly suitable for high-temperature and high-pressure industrial applications.
International ISO standard:ISO 16228 is the international standard for boilers and pressure vessels level gauge glass.It includes dimensional tolerances, thermal shock performance and chemical corrosion resistance inspection requirements.It serves as a crucial reference for procurement in global industrial projects.
All of our sight glass products strictly comply with these industry standards and specifications.We can customize products to meet your specific procurement requirements and provide compliance testing reports throughout the entire process.
