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.

Test Sand & Test Dust

Particles for analysis are suspended in an electrolyte solution. 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.

A view of volume differential particle size data indicates a bi-modal distribution with approximate peaks at 4 and 20 micron size. Particles are measured as they pass through the aperture. Certified and reference values for the cumulative number of dust particles per unit volume of hydraulic oil isp than the specified particle diameter are reported. 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.


Test Sand & Test Dust

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 may penetrate into cracks, crevices, bearings, and joints.

Shanghai Jun Yu Trade Co. Standard Materials for Calibration. The Multisizer IIe analyzer measures particles individually by volume mass. 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 12103.

RoomBuilding 5, No.

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.

It specifies four grades of test dust including dust description, designation, particle size distribution, particle size analysis procedure, and chemical content. The nominal specific gravity is 2.

Material Safety Data Sheet. Share this product Tweet. Four grades of test dust are designated in ISOa description of each is as follows: Particle size limits specified per ISO are expressed as cumulative volume percent smaller than and listed as follows: The suspension is stirred and drawn through an aperture using a vacuum source. 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 documents where test dust use is required.


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.

Certified values for particles sizes from 1 micron to 30 microns are provided. It was originally developed for testing automotive cabin air filters. Future revisions of ISO will accommodate changes in technology affecting test dust manufacturing processes and insure product isk for years to come.
