Share this product Tweet. Sold in gram net weight quantities b Packaging can be customized to accommodate the larger quantity ordered c Bulk Density: The suspension is stirred and drawn through an aperture using a vacuum source. It specifies four grades of 112103-1 dust including dust description, designation, particle size distribution, particle size analysis procedure, and chemical content.
ISO A2 Fine Test Dust
Certified values for particles sizes from 1 micron to 30 microns are provided. Although it is not currently specified as a suitable contaminant for cabin air filters, it is used as a test contaminant for fuel system isk, water filter performance evaluation, and other custom applications. Particle size limits specified per ISO ieo expressed as cumulative volume percent smaller than and listed as follows: The bi-modal aspect of this product traces back to the original roller analysis specification of Fine Test Dust shown in former revisions of SAE J Specification.
West Coast Sales Sparks Blvd.
A view of volume differential particle size data indicates a bi-modal distribution with approximate peaks at 4 and 20 micron size. A naturally occurring irregularly shaped mineral dust suspended in hydraulic oil at a nominal concentration of 2.
The small particle procedure, using fine dust is performed to ascertain the ability of equipment to resist the effects of fine particles which uso penetrate into cracks, crevices, bearings, and joints. Shanghai Jun Yu Trade Co.
Test Sand & Test Dust
Particles are measured as they pass through the aperture. Standard Materials for Calibration.
Material Safety Data Sheet. Certified and reference values for the cumulative number of dust particles per unit volume of hydraulic oil greater than the specified particle diameter are reported.
Consists of 20 grams of dry dust taken from the same lot as the dust in SRMand is ido with reference values from 1 micron to 50 microns. The nominal specific gravity is 2. Particle counting is a mainstay of contamination control in hydraulic, automotive, and aerospace applications.
Particle sizes greater than 30 microns are given as reference values. Samples from only 21103-1 batches were used because only two batches of this type dust were produced prior to when ISO particle size limits were determined.
Future revisions of ISO will accommodate changes in technology affecting test dust manufacturing processes and insure product consistency for years to come.
Test Sand & Test Dust
Particles for analysis are suspended in an electrolyte solution. It was originally developed for testing automotive cabin air filters. The Multisizer IIe analyzer measures particles individually by volume mass.
RoomBuilding 5, No. Four grades of test dust are designated in ISOa description of each is as follows: To the best of our knowledge since we are an active global distributor of all test dust and sands, ISO test dust is a non- contaminant and non-hazardous Class 60 material. The intent in producing a separate standard for the description of test dust was to provide a simple and accurate test dust reference for use in other standards or 1103-1 where test dust use is required.
