Scope

This part of GB/T 1479 specifies the method for measuring the apparent density of
metal powders with a funnel under standard conditions.
This part applies to metal powders that can flow freely through a funnel with a pore
diameter of 2.5 mm. If the powder is difficult to pass through a pore with a diameter of
2.5 mm but can flow freely through a 5.0 mm pore, this method can also be used.
Part 2 of this standard (see GB/T 1479.2) specifies the apparent density measuring
method for powders that cannot pass through a 5.0 mm pore.

Summary	This standard specifies the funnel under standard conditions with metal powder bulk density measurement method. This section applies to freely flow through the aperture of 2. 5mm metal powder funnel. If the powder is difficult to pass a 2. 5mm diameter holes, but can freely flow through the 5. 0mm hole, the method can also be used. In this standard, Part 2 (see GB/T 1479. 2) can not be specified in a 5. 0mm diameter of the powder bulk density measurement method.
