Test methodology requires glass test tubes 110 mm long, with an outer diameter of approximately 5 mm and an inner diameter of (4,0 ± 0,5) mm, universal indicating paper (pH range of 1 to 10), and a thermostatically controlled heating apparatus for the temperature specified in the standard of the cable type being tested.
The temperature is controlled by heating a solid aluminium block with a digital temperature controller to maintain constant uniform heat throughout the testing.
- Thermal Stability Test Apparatus incorporates a specially designed HEATING BLOCK which eliminates the use oil.
- The apparatus is designed to measure/check thermal stability of PVC Insulation and Sheath of Electric Cables in a temperature controlled heating chamber.
- It measures thermal stability time in minutes required to change the pH of 5 to 3 of a universal indicating pH paper placed in a glass tube of specified dimension & heated in a temperature controlled heating chamber at specified temperature of 200 +/- 0.50C.
Accessories:
- pH paper roll
- Test Tubes – Manufactured in Germany │Length: 110mm, Outer Diameter: 5mm, Inner Diameter: 4mm +/- 0.5mm (Minimum Order Quantity 1000 Nos.)
