27、 as to whether the products may be used without restriction in any of the Member States of the EU or EFTA; b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in
28、force. !NOTE 1“ Conformity with this European Standard does not confer or imply acceptance or approval of the products in any of the member states of the EU or EFTA. The use of the products covered by this European Standard is subject to regulation or control by national authorities. !NOTE 2 These p
