General requirements The specified markings shall be applied — either on the body, or — on plates integral with the body or securely fixed on the body In no case shall the markings be hidden by the fixing elements of the steam trap Optional markings — Nominal pressure (PN) — Maximum operating pressure, or maximum differential pressure, according to the relative significance of each one — Shell material designation3) — Nominal size (DN) — Maximum test pressure (bar or MPa) Additional markings A manufacturer having complied with the above requirements may a) mark any of the above mentioned items in more than one place; for example, if an item is marked on the body, it may also be repeated on the identification plate; b) add any other markings, for example, catalogue item numbers, providing that there is no risk of confusion between these markings and those mentioned above ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ Mandatory marking The following items shall be mandatorily marked on the automatic steam
