EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62899-202-4 testing. IEC EN 62899-202-4 defines the terminology and measurement methods for the properties of stretchable printed layers, such as conductive ink, stretchable conductive films from conductive ink, and stretchable printed cables formed, to form stretchable conductors by printing.

Stretchable printed layers (conductive and insulator) covered by this standard are for example fabric-integrated wearables, skin-patched devices, etc. It applies to stretchable electrical cables printed on tensile substrates such as
The IEC EN 62899-20x series mainly deals with measurement methods for printed electronics. The series also includes storage methods, packaging and marking, and shipping conditions. The IEC EN 62899-20x series is divided into sections for each material. Each part is prepared as a general specification that includes basic information for the printed electronics field.
Each part will also contain the section properties, blank detail properties, and detail properties of each material. This part of IEC EN 62899 deals with stretchable printed layers (conductor and insulator) used in printed electronics and includes test conditions, measurement methods and storage conditions.
However, if the part without functional layer expands selectively, and the elongation of the functional layer is obviously smaller than the elongation of the substrate parts, the stiffness of the functional layer is judged to be high.
The substrate must not break at the maximum stretch length of the conductive film during measurement. The substrate for the test piece should be at least a stretchable substrate that is predicted to have a higher tensile strength than the conductive layer to be measured. The type of flexible substrate materials can be chosen as agreed between the user and the supplier.
