This Standard specifies the funnel method for the determination
of the apparent density of metallic powders.
The method is intended for metallic powders that flow freely
through a 2.5 mm diameter orifice. It may, however, be used for
powders that flow with difficulty through a 2.5 mm diameter orifice
but flow freely through a 5 mm diameter orifice.
NOTE: The International Standard corresponding to this Standard
and the symbol of degree of correspondence are as follows.
ISO 3923-1:2008 Metallic powders-Determination of apparent
density- Part 1: Funnel method (MOD)
In addition, symbols which denote the degree of correspondence
in the contents between the relevant International Standard and
JIS are IDT (identical), MOD (modified), and NEQ
(not equivalent) according to ISO/lEC Guide
