Product Overview

The Hot Set Test Apparatus HST-151-HMI is a precision test system designed to evaluate the elongation, deformation, and permanent set of cable insulation and sheathing materials at elevated temperatures. The apparatus conforms to IS 10810 : 1984 Part 30 and meets the hot set test requirements specified in IS 7098.

The unit consists of a double-walled, temperature-controlled oven that ensures uniform heating and stable test conditions. The stainless steel inner chamber provides excellent corrosion resistance and long service life.

Temperature & Airflow Control

The oven is fitted with a PID temperature controller in HMI Display offering dual digital display for both set value and actual process temperature. The system is capable of maintaining the required 200 °C ± 3 °C test temperature with high stability.

Controlled airflow is achieved through a bottom air inlet, ensuring air flows evenly across the surface of the test specimens before exiting near the top of the chamber. The airflow rate is monitored and regulated using a rotameter, providing consistent test conditions as required by the standard.

Specimen Mounting & Load System

Two specimens can be tested simultaneously using top-mounted hanging grips. Each specimen is subjected to a controlled load using calibrated weights up to 1 kg, allowing accurate evaluation of elongation under thermal stress. The full-view glass door enables continuous observation of specimen behavior during the test.
