Question 1:

One of our customers requires us to determine the application case according to ELV Annex II of a component.
However, I cannot select an application here because the required tab is not available.
My question therefore: Is it even possible to set an application case for a semi-component or does the entry have to be created again, only this time as a component?


You are absolutely right. The application code is only set when the semi-component is referenced in a component. So, in our opinion, you cannot set an application code.

Question 2:

Is there any LED data from ZVEI that apply to all LEDs?

The background to this question is the following rejection text regarding LEDs in the ZVEI PCB-Assy:

"Please declare the missing LED, this is not covered by the published data sheet from ZVEI because of the declarable substances like Indium, Galium arsenide, etc . Please ask your LED supplier to send to you the IMDS data sheet and report it in your IMDS data sheet."


There is no published LED data from ZVEI or other associations in the IMDS. So you have to request your suppliers for the LED MDS.

Question 3:

Why has my MDS with a German material name recently been rejected?


Since May we have the new release 12 in the IMDS and the material names are no longer supported in German. Therefore, all material names must now be maintained in English. For example, if you had "HAL ohne Blei" in a material MDS and you are now copying it, so it has the German name in the English field. This is not allowed, you would have to replace it with "HAL leadfree".
This rule counts from Rec001:

Question 4:

Daimler repeatedly rejects materials for the following reason: Please do not mix different materials. Report each homogenous material separately. Please read IMDS Recommendation 001.


Materials are often rejected in IMDS. A common reason is the mixing and combining of different materials. Using two examples, we will explain to you what has to be taken into account for homogeneous materials.

In the case of homogeneous materials, the definition must be observed exactly. Homogeneous means a consistently homogeneous material composition that cannot be mechanically broken down into different materials. Mechanical decomposition in this case means a possible separation by mechanical processes such as cutting, turning, grinding. Examples of homogeneous materials are: Plastics, metals, alloys and coatings.

This is the definition adopted by the responsible group in the VDA. It is based on the definition of the EU legal department and is also supported by both the European Automobile Industry (ACEA) and the automobile associations of the other regions.


Figure 1 shows a material called "copper wire". This material contains the pure material "copper" and a base polymer called PVC (polyvinyl chloride) for the insulator shell.

Figure 1:

FAQ4 01

The copper content and the PVC content can be mechanically separated after processing, therefore copper and PVC must be indicated in IMDS in the form of separate materials. The material shown above must therefore be rejected in the IMDS, it is not "homogeneous"!

The following diagram shows an example of how "copper wire" could look right in IMDS:

Figure 2:

FAQ4 02

Copper and the base polymer PVC are indicated as separate materials (green symbols). In this case "copper wire" is a semi-finished product (yellow symbol), as the insulator sheath is part of the copper cable.
