Gibitre Thermal Block
Thermal regulated Block for the performance of ageing tests in air and in liquids of elastomeric materials at temperatures up to 250°C


Standards the instrument complies with:   
ASTM D471;   ASTM D865;   ASTM D1056;   AS_NZS 4179;   EN 681-1;   ISO 188;   ISO 1817;   ISO 6916-1;   ISO 6916-2;   VDA 675-301;    

Overview 
Thermal regulated Block for the performance of aging tests in air and in liquids of elastomeric materials at temperatures up to 250°C conforming to ISO 188, 1817 ASTM D 471 and 865 Standards.
Aging tests are typically carried out to measure the variation of characteristics of an article before and after the aging process. The characteristics that are most frequently measured before and after aging are:
• Variation of mechanical characteristics (loading, lengthening, tearing)
• Variation of hardness
• Percentage variation of mass and volume.
Gibitre, in addition to providing this tool to perform accelerated aging in air or in liquid, also provides the tools to measure changes in the properties of the article and to produce the related reports.

Instruments Characteristics  
The instrument is fitted with:
• Aluminium block contained in a stainless steel housing with thermal insulation with 4 calibrated holes designed for the insertion of 4 glass test tubes
• Heating resistance
• PT 100 thermal probe for temperature measurement
• PID thermoregulator
• Timer for the set of the heating time with automatic switch off of the heater at the end of the set time


Timer 
The instrument is equipped with a timer that can be set between 0 and 99 hours and 59 minutes. The instrument automatically stops at the end of the set test time.
The Timer allows you to activate aging cycles by ending the test automatically in the absence of the operator.




Glass Tubes for samples. 
4 glass tubes with a diameter of 38 mm and a length of 300 mm can be inserted into the instrument.
The specimens can be inserted into the glass tubes and locked using the fasteners provided.
Fixing devices allow the specimens to be placed in order to avoid contact with the glass tube walls.


Glass Tubes for test according to ASTM D865 
The glass tubes are closed in the upper part with PTFE plugs provided with holes for the insertion of the glass pipes requested for the aging test in hot air according to ASTM D865

Water-cooled reflux condenser 
For aging tests in volatile liquids it is necessary to use condensation columns connected to a water supply. The condensation columns allow to condense the volatile part of the test liquid and make it fall back into the tube. In this way, the amount and formulation of the liquid in the glasses will remain unchanged.
A condensation column can be applied to each test tube.




Removable Side Supports 
Together with the instrument are supplied two side supports for housing the glass tubes not in use. The supports can be removed to reduce the overall dimensions of the instrument.

Safety Devices 
• Safety switch to prevent overheating
• Safety Push-button
• CE Labelling


Standard Calibration service for a Block Oven 
The calibration is performed with reference to the requirements of ISO 1817 standard.
The service includes:
• Ordinary maintenance of the instrument
• Calibration of the temperature inside the testing tubes (at 70°C, 150°C, 200°C, 250°C).
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.




Development and production 
The instrument is totally developed and produced in the plant of Gibitre Instruments in Italy.
All the mechanical parts are produced in the company workshop using modern CNC machines.
Components and sensors from well-known brands are selected in order to ensure the maximum reliability in the measures
Internal trained personnel takes care of all the production stages: assembly, start-up, calibration, packing, shipment and installation.
