Why cannot the results of the European ISO 9239-1 test be transferred to the American ASTM E648 standard, even though both procedures are performed with the Radiant Panel device?

The test procedures differ in terms of air velocity settings, conditioning time, and test duration, among other things. In addition, the ASTM E662 standard must be used to measure smoke density.

The new version of ASTM E648 now also includes changes to the calibration procedure (calibration frequency, number of referencepoints). The calibration procedure verifies that the requirement for heat flow (heat impact) on the sample surface is met.

It is important for you to know that we can ensure the test and calibration requirements for both test methods.

Standardization is an important part of our modern economy. It ensures that products meet uniform standards. This increases quality, safety, and efficiency while creating a reliable basis for innovation. 

In the field of floor coverings, several relevant standards have been revised and adapted to the current state of the art. We have summarized the most important changes for you.  

Please contact us for further details! 

EN ISO 10833 – Textile floor coverings – Suitability at cut edges 

- Adjustment of the evaluation and classification criteria 

EN 1815 – Resilient and textile floor coverings – Determination of electrostatic charge during walking (walking test) 

- Specification of test conditions, in particular the sole material 

EN 14215 – Classification of rugs and runners 

- Addition of use classes in the commercial area (classes 31-33) 

Drum test and appearance change of textile floor coverings 

In the previous test standard ISO 10361, the two methods were combined with the Vettermann drum and the hexapod test. With the new revions, each method now has its own test standard: 

- ISO 23122 – Hexapod test 

- ISO 23106 – Vettermann drum 

The test procedures and methodology remain unchanged for both tests. 

Flexible accreditation of the TFI by DAkkS – explained simply 

Flexible accreditation is a special form of recognition by the German Accreditation Body (DAkkS). 

Flexible accreditation allows the TFI to: 

- Adapt or further develop test procedures within a specified area 

- Apply new or amended standards 

This enables us to: 

✔️ Respond more quickly to changes in standards 

✔️ Tests according to the latest standards without delay 

✔️ Implement technical developments efficiently
