Standard test dust
The Arizona test dust A1 ultrafine forms the finest standard dusts of ISO 12103-1 and is used for various filter and environmental tests.
The so-called Arizona test dust A1 ultrafine consists of 69 % - 77 % quarz.
The specified particle size distribution is shown in the following table:
|x (µm)||Q3(x) (%)|
|0.97||3.0 - 5.0|
|1.38||7.0 - 10.0|
|2.75||23.0 - 27.0|
|5.50||65.0 - 69.0|
|11.0||95.5 - 97.5|
Transport and Storage
Partial segregation may occur during transport and storage. It is therefore recommended to homogenize the PTI Arizona Test Dust A1 ultrafine before use, which can be achieved by mixing with a laboratory tumbler mixer. Please store in a dry and airtight original container.
In order to achieve reproducible quality, the raw materials and production are strictly controlled. The following quality controls are carried out:
Monitoring the particle size distribution of raw materials
Monitoring the particle size distribution of the end product
