Specifies the properties of powders and bulk materials that are commonly used when designing continuous handling equipment systems for powders and bulk materials.

This British Standard describes the properties of powders and bulk materials that are commonly used when designing continuous handling equipment systems for powders and bulk materials. The standard gives guidance on methods and procedures for the determination of these characteristics.

This standard does not describe the following properties:

  1. combustibility;
  2. electrical properties;
  3. explosibility;
  4. flammability;
  5. thermal properties;
  6. hygiene;
  7. toxicity.

NOTE For information on items a) to e) attention is drawn to The Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres (Amendment) Regulations 2001 [1].

This standard is not applicable to the following categories of materials:

  1. materials that do not behave as powders or bulk materials (for example cakes, sludges, saturated and drained materials, slurries);
  2. frozen materials;
  3. chemically reactive materials (for example which solidify on exposure to air) unless an inert atmosphere can be maintained;
  4. fibrous or stringy materials whose particles interlock.
