Translation into English of the Regulations originally abstracted as CIS 90-1438. They became effective on 1 Jan. 1989 and relate to pressure or vacuum vessels, open tanks and pipe systems for liquids or gases. These new directives are a revised and amended version of AFS 1986:9 (corrected in AFS 1987:5), which they replace. The main alterations are changed inspection and checking requirement for some types of pressure vessels. Contents: definitions; sales specifications; compliance testing (new, repaired, and modified equipment); welders' qualifications; application for authorisation of heat treatment; verification of calculations and final testing; checks to be made by the manufacturer; periodic inspections; special provisions concerning welded vessels.

Electrode boilers for maintaining the steam pressure
Elektrodångpanna för tryckhållning [en sueco]
This directive (effective 1 June 1983) applies to electrode-heated steam boilers where the water is rendered conductive by addition of salts and forms the electric resistance. These boilers present an explosion hazard because of the mixture of hydrogen and oxygen which may form and accumulate during operation. Measures to be taken are: bottom blow-down at least once a day; boiler-water conductivity to be checked once every month; expansion-vessel pressure to be relieved and vessel to be blown-down once every week; safety procedures prior to inspections and repairs (de-energising, gas freeing, depressurising); metered addition of salt. A commentary is appended.

The corners should be reinforced by triangles of a least 0.15 the height of the boiler. The boilers should be inspected internally and externally once a year; inspection holes should therefore be fitted at specified points. Commentary.
