Particles are measured as they pass through the aperture.

Particles for analysis are suspended in an electrolyte solution. The intent in producing a separate standard for the description of test dust was to provide a simple kso accurate test dust reference for use in other standards or documents where test dust use is required.

Four grades of test dust are designated in ISOa description of each is as follows: Although it is not currently specified as a suitable contaminant for cabin air filters, it is used as a test contaminant for fuel system components, water filter performance evaluation, and other custom applications.

Samples from only two batches were used because only two batches of this type dust were produced prior to when ISO particle size limits were determined. It specifies four grades of test dust including dust description, designation, particle size distribution, particle size analysis procedure, and chemical content.


Test Sand & Test Dust

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. Standard Materials for Calibration. The Multisizer IIe analyzer measures particles individually by volume mass. It was originally developed for testing automotive cabin air filters. Particle counting is a mainstay of contamination control in hydraulic, automotive, and aerospace applications. Sold in gram net weight quantities b Packaging can be customized to accommodate the larger quantity ordered c Bulk Density: The small particle procedure, using fine dust is performed to ascertain the ability of equipment to resist the effects of fine particles which may penetrate into cracks, crevices, bearings, and joints.


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. The nominal specific gravity is 2.

ISO A2 Fine Test Dust

The suspension is stirred and drawn through an aperture using a vacuum source. A view of volume differential particle size data indicates a bi-modal distribution with approximate peaks at 4 and 20 micron size. Consists of 20 grams of dry dust taken from the same lot as the dust in SRMand is provided with reference values from 1 micron to 50 microns. West Coast Sales Sparks Blvd. A naturally occurring irregularly shaped mineral dust suspended in hydraulic oil at a nominal concentration of 2.


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. Particle sizes greater than 30 microns are given as reference values.

Material Safety Data Sheet. Shanghai Jun Yu Trade Co.

Share this product Tweet. Particle size limits specified per ISO are expressed as cumulative volume percent smaller than and listed as follows: Future revisions of ISO will accommodate changes in technology affecting test dust manufacturing processes and insure product consistency for years to come.

RoomBuilding 5, No. Certified values for particles sizes from 1 micron to 30 microns are provided.
