The heat flow meter (HFM) method is mainly used to test thermal conductivity and thermal resistance of insulation samples. It is not an absolute method, therefore, the heat flow meter output needs to be calibrated with a standard material. NETZSCH-Gerätebau GmbH has recently qualified its own factory standard for calibration and validation of heat flow … Read moreNETZSCH EPS – A New and Affordable Standard Material for Testing Thermal Conductivity with HFM Instruments
There are many applications for a Heat Flow Meters – but is it the right measurment method for thermal conductivity for my material or product?
Saving energy – this applies in the course of the Paris Agreement on Climate Change at international level. Awareness of the reduction of CO2 emissions is growing. Most countries have set themselves ambitious goals. In other words: a good sign for a positive development of the insulation market.
The ift-Rosenheim (Institute for Window-Technology) released the Guideline WA-17/1!
The guideline was written for the determination of the equivalent thermal conductivity of thermally improved spacers (warm edge).
NETZSCH has implemented this measurement routine into their Heat Flow Meters.
Day-to-day measurements on your production samples can be calculated in terms of the statistical measurement value λ90/90 by a single mouseclick. This is the basis for determining the CE-compliant nominal value of the thermal conductivity, λD.
This article shows the relationship between the thermal conductivity and the Lambda 90/90 Value, which is the leading parameter for the CE-Declaration on insulating materials in Europe.
