  Imported standardsFor example, the European Pharmacopoeia, American Pharmacopoeia, Japanese Pharmacopoeia, etc., there is no electronic version of the manual part of the pharmacopoeia standard product. If there is a paper version, it will be shipped with the goods. For the electronic version of some standard product instructions, you can check on the relevant brand websites.
