The manufacturer also furnishes directions which should be followed except as amended as follows.Particular attention should be given to proper manintenance of the instrument with special reference to the instructions on (1) periodic checking of water level in the pressure regulator standpipe,(2) manometer level before the sample tube is inserted, and (3) the sample packing assembly.
What are particular attentions when using fisher sub sieve sizer according to ASTM B330 Standard Test Method for Fisher Number of Metal Powders and Related Compounds?
What is the explanation of Repeatability according to ASTM B213 Standard Test Method for Flow Rate of Metal Powders by using a hall flowmeter funnel?
Repeatability intervals,r,are listed in Table 1 in ASTM B 213.In 95% of flow rate determinations,on the basis of test error alone,duplicate tests in the same laboratory by the same operator on one homogeneous lot of powder will differ by no more than the stated amount in seconds.
How to do in case of a non-free-flowing powder during powder filling using a scott volumeter according to international standard ISO 3923-2 metallic powders-Determination of apparent density-Part 2 scott volumeter method?
If the powder is not free flowing,its passage through the sieve may be aided by light brushing with a soft brush.
What are relation between USP 616 Bulk Density and Tapped Density of Powders and European Pharmacopoeia and Japanese Pharmacopoeia?
USP 616 Bulk Density and Tapped Density of Powders has been harmonized with the corresponding texts of the European Pharmacopoeia and /or the Japanese Pharmacopoeia. The portion that is not harmonized is marked with symbols to specifiy this face.
What is the name of USP 616?
USP 616 is Bulk Density and Tapped Density of Powders
Where to buy replacement parts of fisher sub sieve sizer/average particle size analyzer recommended by ASTM B 330 Standard Test Method for Fisher Number of Metal Powders and Related Compounds?
Necessary replacement parts should be obtained from the manufacturer, that is AimSizer Scientific Ltd. especially in the case of the precision manometer which is a part of the air flowmeter.

What is the explanation of Precision according to ASTM B213 Standard Test Method for Flow Rate of Metal Powders by using a hall flowmeter funnel?
The precision has been determined from an interlaboratory study performed by seven laboratories of Sub committee.AimSizer took part in the interlaboratory research and has become a major participant in such research and the original manufacturer of calibration powder chinese emery.
How to fill the density cup of a scott volumeter according to international standard ISO 3923-2 metallic powders-Determination of apparent density-Part 2 scott volumeter method?
Pour or feed the powder carefully by means of a spatula into the funnel until the cup is completely filled and powder flows over.

What is test method 2 of international standard USP 616 Bulk Density and Tapped Density of Powders using a tap density tester?
The method 2 is approximately same as method 1, operator proceeds as directed under Method I except that the mechanical tester provides a fixed drop of 3+-0.2 at a norminal rate of 250 taps per minute.
What are apparatus of a fisher sub sieve sizer/average particle size analyzer according to ASTM B 330 Standard Test Method for Fisher Number of Metal Powders and Related Compounds?
The fisher sub sieve sizer consists of an air pump,an air-pressure regulating device,a precision-bore sample tube,a standardized double-range air flowmeter,and a calculator chart.Included is accessory equipment consisting of a plug manipulator,powder funnel,two porous plugs,a supply of paper disks,and a rubble tube support stand.
