"3.5 The Customer or a third party appointed by the Customer may temporarily appoint to a Resource also tasks which are outside the scope of the Services or the expertise of the Resource."
In other words, this clause forces the contractor to TRY to perform work outside their competence -- totally in violation of any code of ethics I've seen.
Here's another classic (not really related to the code of ethics -- just an example of a really, really, really bad clause...)
"The Customer is entitled to freely change, supplement and renew such information and instructions during the validity of this Frame Agreement without a separate compensation to the Supplier."
In other words, this idiot Finnish client expects, that on a fixed-price contract, the customer can change, at will and at any time, the scope or anything else in the contract without needing to compensate the contractor.
Maybe you can work up a set of ethics for the hiring companies
