English to Czech Bus/Financial Engineering: Industrial CDRL, GRD, contracts

(1) "Statement of Compliance" (defined in the document as "An assessment of the supplier indicating the fulfilment of a requirement") is said to be translated as "Prohlášení o souhlasu". Is it correct?

Also, notice the following, which occurs in the same text as well:

(2) "Materials and substances classified as Prohibited shall not be used in the Goods. Compliance is mandatory for the Supplier."

Should I translate this instance of "Compliance" as "souhlas" again?

(3) "In case of non-compliance with any of the requirements relevant to the TRD/ GRD (all sections) the Supplier shall clearly indicate each aspect of non-compliance in his proposal (GRD as part of the bid)".

I wonder if "non-compliance" here will be simply the opposite, hence "nesouhlas", because most dictionaries give "nesoulad".

(4) In "To ensure that Buyer products are in compliance with upcoming legislation and common customer requirements...", I would rather use "v SOULADU s". Would that be OK?

(5) In "The Supplier shall conduct EMC tests in the following areas to ensure compliance with EN xxxxx..." I'd probably use "soulad" rather than "souhlas", again.

(6) "...demonstrating that the product is safe by showing compliance with all safety requirements..." "SOULAD" here, too, right?

Other examples: "...shall be able to demonstrate compliance to all of the requirements..." with "to" as the preposition. No change of meaning here?

I can imagine other synonyms or near synonyms, like "shoda", but I don't know what's the most frequent and suitable Czech equivalent.

Thanks a lot for any advice!
