Background

Separations are introduced into the test method by using the Manage Separations button. Each separation will have its own section in the worksheet. There will be other structural changes made to the worksheet, which will vary depending on the number of separations.

The number of separations, allowed or required, on a worksheet depends on the test method used.

Structural Changes

The number of separations used in a sieve test causes changes to the appearance of various sections and to the workflow of the test.

The Separation sections are where the information about the separations (splits) are stored.

This type of section usually contains a minimum of two subsections:

1. A read-only subsection where the size of the separation sieve and other information about the sample and subsample are displayed.

2. A second subsection where the weighing details of the sample and subsample can be recorded.

The structure and content of this section can change due to differences between test methods and changes caused by the timing of washing and/or drying the specimen.

• When drying occurs immediately after separation, a drying sub-section is added to the section.

• In worksheets where the washing process uses another test method, the washing procedure is implemented as an embedded test (Associated Test Results), and appears in the appropriate Separation section, based on the timing of washing.

Separation 1 Section

Open

A Separation 1 section is basically identical to a Separation section in appearance and functionality.

The main difference is in the names and the references to other portions used in the sieve test.

Separation 2 Section

Open

A Separation 2 section is basically identical to a Separation section in appearance and functionality.

The main difference is in the names and the references to other portions used in the sieve test.
