Hot set tester, EB 16-II

The EB 16-II hot set tester is made for hot set testing of cable material according to IEC 60811-2-1 and other equivalent standards.

To avoid too high temperature loss when inserting and cutting the samples, the samples are introduced through a small opening in the top of the oven. To get a suitable working height and not shake the samples during insertion, the oven is fixed and the sample holder moves up and down by a servo motor driven screw system.

The oven has a low air speed and an air exchange rate which is controlled by a flow meter, meeting the requirements for ageing ovens in IEC 811.

Measurements are made through the window with a laser pointer mounted on a measuring scale placed on the door. The window can be taken apart for cleaning. When measuring the elongation with a push on a button on the scale, the measured values are entered into a spreadsheet template, via a Bluetooth connection.

The templates are for testing 3 flat samples, 3 round samples, 4 flat samples with possibility to have 2 different materials, and 4 round samples with possibility to have 2 different materials.

The set is measured outside the oven with a digital caliper also connected to the computer through a Bluetooth connection. A finished report can then be produced in a spreadsheet software.
