Overview 
Tests at low temperatures permit to evaluate the crystallization effects and to compare viscoelastic properties of rubber and rubber-like materials at low temperatures. Temperature Retraction and Brittleness Point tests are useful for the selection of materials suitable for low-temperature service.

The structure of the Low Temperature Check has been designed to permit the installation of arrangements for TR and Brittleness point tests.
The structure includes all common parts required for low temperature testing:
• 5 litres thermal insulated stainless steel bath for cooling liquid.
• Heat exchangers for bath cooling & thermal resistance for bath heating
• Temperature controller with 0.1°C resolution
• Stirrer for bath homogenization
• Electronic card for the complete control fitted with usb port for connection to pc.
• Safety devices: independent bath overheating controller, thermal switch, pneumatic lock for sample holders.

Temperature Retraction (TR) Test: Instrument Setup 
The arrangement for TR test includes:
• Sample holder for the simultaneous test of 6 samples
• Pneumatic lifting system for the easy handling of the sample holder
• Windows bases software for TR test performance
The Sample Holder makes it possible to:
• Carry out simultaneous testing on 6 samples.
• Read automatically the retraction of each sample with 0.02 mm resolution
• Lock sample position in extended position during test preparation
• Automatically release of test samples at the end of the conditioning time.

TR Test Software 
The software permits to:
• Select the Test Procedure, which autmatically sets the instruments
• Enter samples identification (up to 3 products)
• Cool and condition the samples
• Start the test
• Plot Retraction Curves for each sample
• Calculate test results and statistics
• Check tolerance limits for each product
• Save results and curves in the standard Gibitre SQL Database

Brittleness point test: Instrument setup 
The arrangement for Brittleness Point test includes:
• Pneumatically actuated striker
• Sample holder for the simultaneous test of 10 samples
• Windows bases software for Brittleness Point test performance
• Datagest software for database management.

The striker is in compliance with international standards and the clearance can be set according to the kind of test (4.8, 5.2, 5.7, 6.4 mm). A pneumatic piston drives the striker and permits to perform the tests while the samples are immersed in the cooling liquid. A pressure regulator enables the speed of the striker to be adjusted in compliance with standards depending from the number of samples and the density of the cooling liquid in use.
The software permits to prepare and store test procedures with custom test conditions.

• Select the Test Procedure, which automatically sets the instrument
• Cool and condition the samples
• Activate the striker at the end of the conditioning time for the sampes
• Record the temperature and the speed of the striker
• Allow the user to enter test results after visual inspection
• Prepare the instrument for the next test Temperature
• Calculate and save Brittleness Point Temperature

Datagest program 
The Datagest program is the database management tool always installed in combination with all Gibitre instrument-control programs.
The program permits to:
• Select, filter, print, export and analyse the test results stored with all the instruments connected.
• Prepare test procedures by defining the test conditions and the results to be produced
• Set tolerance limits for each product by manual insertion or using the statistical analysis (mean and standard deviation) of saved results
• Prepare multi-instrument test reports

Gibitre Standard SQL Database 
All the Gibitre programs use a database with SQL structure for saving the results.
The database can be installed inside an SQL instance present on the company server or it can be installed on a PC connected to a measuring instrument. The installation of the Microsoft SQL service (Express version) is included in the delivery.
