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.
Test Sand & Test Dust
West Coast Sales Sparks Blvd. RoomBuilding 5, No. 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. Particle sizes 1213-1 than 30 microns are given as reference values.
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. Consists of 20 grams of dry dust taken from the same lot as the dust in SRMand is provided with reference values from iao micron to 50 microns.
Shanghai Jun Yu Trade Co. Particles for analysis are suspended in an electrolyte solution. The nominal specific gravity is 2.
Particle size limits specified per ISO are expressed as cumulative volume percent smaller than and listed as follows: The Multisizer IIe analyzer measures particles individually by volume mass. 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.
Standard Materials for Calibration. Particles are measured as they pass through the aperture. The suspension is stirred and drawn through an aperture using a vacuum source. It specifies four grades of test 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. Four grades of test dust are designated in ISOa description of each is as follows: 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. 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 iiso, and other custom 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 12103- ISO test dust is a non- contaminant and non-hazardous Class 60 material.
12013-1 Particle counting is a mainstay of contamination control in hydraulic, automotive, and aerospace applications. It was originally developed for testing automotive cabin air filters. Share this product Tweet. 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.
Future revisions of ISO will accommodate changes in technology affecting test dust manufacturing processes and insure product consistency for iwo to come.
