在鋼桶上印著兩個日期標記，互相不一致怎么辦？
文/三哥
有時，鋼桶的使用者會詢問是否需要在鋼桶底部印上日期，然后與在側面標上的日期必須匹配，特別是“年”標志。
在新鋼桶底部加印不完整的聯合國標志是根據聯合國6.1.3.2的規定(另見《國際海事危險貨物規則》(IMDG)同一段)。《聯邦法規法典》第49條第178.503(a)(10)條規定：此標識旨在幫助鋼桶翻新和再制造。壓花標志不打算作為桶的聯合國認證標志，在質量超過30kg/L的包裝情況下，需要在側面。
完整標記通常在完全裝配和泄漏測試后，或翻新或再制造后放置在側面。在大多數情況下，新桶是制造的，并在兩個標記位置注明同一年，因為新鋼桶通常是定做的。
在某些情況下，鋼桶的底部可能在最終組裝或完成包裝制造之前被沖壓和壓印標志。在這種情況下，底部和側面標志的年份可能會不同。這是可以接受的，因為表明最終裝配位于鋼桶側面的完整標志是制造商的認證標志(見178.2(b))。
因此，如果桶底在2020年制造并壓印，但直到2021年才組裝成新的桶并進行泄漏測試，那么標記可能會沖突。翻新或再制造的鋼桶通常有沖突的標志，因為翻新修理鋼桶的人必須申請一個新的完整的標志。

Alert 20-03: Marking of the Date on Steel Drums?
Explanation of the two date marks placed on a steel drum during manufacture.?
Occasionally, users of steel drums inquire as to whether or not the date required to be embossed on the bottom of a steel drum and then marked on the side must match, specifically the “year” mark.?
The embossment of an incomplete UN mark on the bottom of a new steel drum is based on a UN requirement in 6.1.3.2 (see also the same paragraph in the International Maritime Dangerous Goods (IMDG) Code). The Code of Federal Regulations Title 49 §178.503(a)(10) states: This marking is intended as an aid for reconditioning and remanufacturing. The embossed mark is not intended as the drum’s UN certification mark, which is required to be on the side in the case of a packaging with a mass of more than 30kg/L.?
The complete mark is normally placed on the side after full assembly and leak testing or after reconditioning or remanufacture. In most circumstances, new drums are manufactured and marked noting the same year in both marking locations as drums are generally made to order. In some cases, the drum’s bottom may be cut and embossed prior to final assembly or completion of manufacture of the packaging. In that case, the year embossed on the bottom and side may differ. This is acceptable since the complete mark indicating final assembly is located on the side of the drum is the mark that is the manufacturer’s certification mark (see 178.2(b)). So, if the drum bottom was manufactured and embossed in 2019 but not assembled into a new drum and leak tested until 2020, then the markings could conflict. Reconditioned or remanufactured drums normally have conflicting marks as the person who reconditions the drum must apply a new complete mark.?
