Re: Kst Pred Values

These values can vary significantly so I would seriously recommend :

1) if you are an end user and it's your powder then get it properly tested as equipment suppliers will expect you to provide this information with an enquiry.

2) if you are providing equipment then your customer must supply the information along with his enquiry.

Using "generic" data is to be avoided as you usually have no way of knowing the exact details of the dust as tested.

Typical values for some common dusts are given in the publications of NFPA (National Fire Protection Association). These are only guidelines, consider running Kst tests to get more exact numbers.
