Future revisions of ISO will accommodate changes in technology affecting test dust manufacturing processes and insure product consistency for years to come. Particle sizes greater than 30 microns are given as reference values.

Test Sand & Test Dust

RoomBuilding 5, No. A naturally occurring irregularly shaped mineral dust suspended in hydraulic oil at a nominal concentration of 12013-1. Particles are measured as they pass through the aperture.

West Coast Sales Sparks Blvd. The nominal specific gravity is 2. A view of volume differential particle size data indicates a 12013-1 distribution with approximate peaks at 4 and 20 micron size.

Particle size limits specified per ISO are expressed as cumulative volume percent smaller than and listed as isso 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. Four grades of test dust 122103-1 designated in ISOa description of each is as follows: 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: 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. Shanghai Jun Yu Trade Co. The suspension is stirred and drawn through an aperture using a vacuum source. 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 Multisizer IIe analyzer measures particles individually by volume mass. It was originally developed for testing automotive cabin air filters.

ISO A2 Fine Test Dust

Certified values for particles sizes from 1 micron to 30 microns are provided. Consists of 20 grams of dry dust taken from the same lot as the dust in SRMand is 112103-1 with reference values from 1 micron to 50 microns. 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.


Particles for analysis are suspended in an electrolyte solution. Material Safety Data Sheet.

Test Sand & Test Dust

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. Standard Materials for Calibration.

The intent in ixo 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 ido dust use is required. Share this product Tweet. 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.
