Foreword
This Standard equivalently adopted ISO 2738.1999 Sintered Metal Materials,
Excluding Hard Metals – Permeable Sintered Metal Materials – Determination of
Density, Oil Content, and Open Porosity.
This Standard modified the following standards like GB/T 5163-1985 Permeable
Sintered Metal Materials – Determination of Density, GB/T 5164-1985 Permeable
Sintered Metal Materials – Determination of Open Porosity, GB/T 5165-1985
Permeable Sintered Metal Materials – Determination of Oil Content. The original three
standards were combined into one standard.
Compared with GB/T 5163-1985, GB/T 5164-1985, GB/T 5165-1985, this Standard
has the major changes in contents as follows.
--- Increase the definition and test method of fully impregnated density in the
determination of density;
--- Increase the definition, test method and calculation formula of oil content
expressed by percentage of the volume of the open porosity in the determination
of oil content;
--- Add the operating methods and precautions of using Soxhlet extractor to
degrease;
--- Increase the surface-coated reagents, paraffin and silicon;
--- Delete the diagram of Soxhlet extraction apparatus;
--- In case when the sample is too large and requires to be broken into small pieces
in the original standard; the density of all small pieces requires to be tested; while
in this Standard, only the representative part of the composition requires to be
tested;
--- For the provision of small test pieces, the volume of which in the original standard
specifies to be less than 0.5cm3; while the mass of which in this Standard
specifies to be less than 5g;
--- When test piece is fully impregnated in the original standard, the maximum
vacuumed pressure on the oil surface is 0.1bar; while in this Standard, it is 70kPa.
The requirements for impregnated oil shall be “generally 20°C-oil with kinematic
viscosities between 50mm2/s and 300mm2/s (50cSt ~ 300cSt)”. Modify the range
between ISO VG20 and VG 150 specified in ISO 3448 into “generally 40°C-oil
with viscosities between 22mm2/s and 68mm2/s; which is equivalent to the range
between VG22~VG68 specified in ISO 3448”;
Sintered Metal Materials, Excluding Hard Metals –
Permeable Sintered Metal Materials – Determination
of Density, Oil Content, and Open Porosity
1 Scope
This Standard specifies methods of determining the density, oil content and open
porosity of permeable sintered metal materials.
This Standard applies in particular to porous metal bearings and to mechanical parts
produced by pressing and sintering metal powders.
