What is ISO 9803-2 about? 

ISO 9803‑2 is the second part of the multi-series European standard that specifies mounting dimensions for vacuum pipeline fittings (elbows, tees, and crosses) of knife-edge flange for nominal bores from 16 mm to 200 mm. 

Who is ISO 9803-2 for? 

ISO 9803‑2 on pipeline fittings in vacuum technology applies to: 

• Manufacturers of vacuum fittings 
• Distributors and suppliers of elbows, tees, and crosses 
• Space researchers and Scientists

Why should you use ISO 9803-2? 

A vacuum fitting is that which extends from a pump's suction side to a vacuum fitting at or below the water line for connecting underwater cleaning equipment. 

ISO 9803-2 includes guidelines for standard design specifications for vacuum pipeline fittings, will assist you in fabricating cost-effective and efficient components of vacuum pipeline fittings. 

ISO 9803-2, which contains the specification of the dimensions for knife-edge flange type vacuum pipeline fittings, will help manufacturers to produce reliable and effective products by ensuring that they conform to the standard quality guidelines
