Product Overview

The Hot Deformation Test Apparatus – Model HD-561 is a precision mechanical testing device developed to determine the heat deformation characteristics of thermoplastic materials, particularly PVC, in compliance with IS 5831 standards. This test evaluates the ability of plastic materials to maintain dimensional stability when subjected to elevated temperatures under a specified load.

The apparatus is supplied complete with a hanger, wedge, and calibrated weights, ensuring easy setup and accurate load application during testing. Specimens are suspended vertically with fixed loading and then exposed to controlled heating conditions using a temperature-regulated oven or bath (external equipment). Deformation is measured after reaching the designated temperature and exposure period.

Constructed using a durable metallic framework, the HD-561 provides stable specimen positioning and consistent load control, delivering repeatable and reliable test results essential for material quality assessment and standard compliance verification.
