Phạm vi áp dụng / Scope of standard

This standard comprises the fundamentals of good practice in
industrial exhaust systems installed to prevent unhealthy or unsafe
environmental conditions or to minimize nuisances.

The scope of these fundamentals is restricted to normal and
typical practice. Practical circumstances, goals and object's, and
special technical problem. encountered In practice cover an
extremely wide range which makes complete coverage in scope
impractical.

Although this standard involves the application of the laws of
fluid flow, as well as other basic scientific concepts, the
purpose is to apply these fundamental concept only to the
range of industrial exhaust systems as encountered In practice.
Generalized fluid flow, for example, is not treated.
