Steam Quality Testing – The Basics

Steam Quality

Steam quality testing as defined by EN285
The Non condensable test
The Dryness test
The Superheat test

The tests involve establishing the physical attributes of dry saturated steam, the gaseous phase of water https://en.wikipedia.org/wiki/Steam
It is the steam supplied to steam sterilizers.

Non Condensable Gas
Non condensable gases are the gases entrained in steam that do not condense back into water when the steam is cooled below its boiling point.Range limit is 0-3.5%

Dryness
The steam dryness fraction is a value used to quantify the amount of water within the steam. For example if steam contains 5% water by mass, it’s said to be 95% dry, or have a dryness fraction of 0.95. Range limit is 0.95 to 1.0

Superheat
The Superheat value is the temperature of the steam as it goes from steam line pressure to atmospheric pressure.Range limit < 25oc above the boiling point of water at your altitude. [/av_textblock]
