Steady-State U-Value Tester for Insulating Glass

Overview

The Steady-State U-Value Tester for Insulating Glass is a device independently developed by our company, based on the b specified in GB/T 22476 Calculation and Determination of Steady-State U-Value (Thermal Transmittance Coefficient) of Insulating Glass—"Measurement of Steady-State U-Value of Insulating Glass by Guarded Hot Plate Method." It is applied to manufacturing enterprises of insulating glass materials, relevant quality inspection departments, units, higher education institutions, research institutes, and other scientific research organizations.

Test Items

Used for measuring the steady-state U-value of insulating glass.

Principle

Under steady-state conditions, within the central metering area of the guarded hot plate apparatus, a one-dimensional steady heat flow is established in a unib plate-like specimen with parallel surfaces, similar to that existing in an infinite plate bounded by two parallel isothermal plates.
