The structure of this standard is as follows: clauses and subclauses preceded by indicate no additional conditions to EN 1559-11)and EN 1559-21); clauses and subclauses marked

20、with a single dot indicate that the conditions shall be agreed at the time of enquiry and order in so far as such conditions do no conflict with the regulatory requirements of the European Union State or EFTA of destination; subclauses marked with two dots indicate that conditions may be agreed at t

21、he time of enquiry and order (optional) in so far as such conditions do no conflict with the regulatory requirements of the European Union State or EFTA of destination; subclauses without dot marking are a requirement of this standard. 1) When complementary information is given in a clause or subcla
