Factory Production Control of Insulating Materials as an Integral Part of CE Conformity
By placing the CE marking on your product, you – as a manufacturer of insulating materials (Construction Products Regulation, CPR – Regulation (EU) No. 305/2011) – are declaring your products are being manufactured in accordance with the European Insulating Standards and that you are upholding the material‘s required performance properties. In order for you to attain CE conformity for your product and certify its quality, external inspection centers first determine your product performance. They examine your product with respect to standards for building materials or requirements for building-authority approval, as the case may be.
After determining the product performance, you can bring your product to market. These external inspection centers will later carry out routine monitoring of your production centers on volunteer basis. Along with these audits and corresponding sampling from your production, it is also firmly stipulated in the European Insulating Materials Standards DIN EN 13162 ff. to DIN EN 13172 that the warranted performance properties are to undergo inspection during production. Volunteer quality marks are for example KEYMARK!
Depending on the insulating material, you may be obligated to regularly check and document any of the following properties via factory production control:
- Fire-safety properties
- Mechanical strength
- Setting and creep behavior
- Water absorption
- Aging behavior
- Thermal conductivity
- And other properties
The external inspection centers also monitor and check the measurement instruments employed, the technical equipment and your documentation.
As a manufacturer of laboratory equipment for thermal analysis and the measurement of thermophysical properties, NETZSCH-Gerätebau GmbH has developed the HFM 446 Lambda instrument series. It allows for determination of the thermal conductivity of insulating materials in accordance with ISO 8301 and ASTM C518 by means of a stationary heat flow. The corresponding instrument-software contains numerous helpful details to keep CE conformity in the determination of lambda values. Lambda here stands for the Greek letter λ as a formula symbol for thermal conductivity.
How To Increase Your Efficiency?
In all areas of industry, our customers around the world benefit from our instruments for determination of temperature-dependent material properties. Moreover, we are always eager to be involved in the production processes of our customers. To address the specific requirements stipulated by standards and legislation, we provide easy and efficient methods with corresponding software solutions.
For you as a manufacturer of insulating materials, the following issues are of crucial importance:
- Routine measurement of the thermal conductivity
- Documentation of the measured values
- Documentation of the long-term stability of the instrument
- Statistical evaluation of the measured values
Our HFM 446 Lambda instrument along with its appertaining software offers you a comprehensive tool to meet these needs. Day-to-day measurements on your production samples can be calculated in terms of the statistical measurement value Lambda 90/90 by a single mousecklick. This is the basis for determining the CE-compliant
Perhaps you already have non-NETZSCH measuring instruments in your quality control system and would like to include test results from these in your statistical evaluation? No problem. Don‘t hesitate to contact us and we will provide you with appropriate import filters after screening your data.
Our comprehensive reporting possibilities will facilitate documentation for you and ensure that your factory production control will always be documented in a fully traceable manner.
