There are many applications for a Heat Flow Meters – but is it the right measurment method for thermal conductivity for my material or product?
This article shows how the thermal conductivity of vacuum insulation panels can be determined – traceable to international thermal conductivity standards!
In Bezug auf unsere Wärmefluss-Messplatten-Geräte zur Ermittlung der Wärmeleitfähigkeit nach DIN EN 12664, DIN EN 12667 oder DIN EN 12939 tritt immer wieder eine Frage auf, die wir mit diesem Beitrag klären wollen: Was ist der Unterschied: “Nennwert” und “Bemessungswert” der Wärmeleitfähigkeit?
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.
