ISO 9803‑1 is the first part of the multi-series European standard that specifies mounting dimensions for vacuum pipeline fittings (elbows, tees, and crosses) of non-knife-edge flange for nominal bores from 10 mm to 250 mm of the R5 series.
ISO 9803‑1 on pipeline fittings in vacuum technology applies to:
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 9803-1 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 9803-1, which contains the specification of the dimensions for non-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.
BS ISO 9803‑1:2020 supersedes BS ISO 9803‑1:2007, which is withdrawn. BS ISO 9803‑1:2020 includes some technical changes concerning BS ISO 9803‑1:2007. These include:
