Forty-first session

Geneva, 25 June – 4 July 2012

Item 4 (d) of the provisional agenda

Electric storage systems: packagings for large lithium batteries

Large Packaging (LP) Packing Instruction for Lithium Batteries

Transmitted by the Rechargeable Battery Association (PRBA) and the International Association for the Promotion and Management of Portable Rechargeable Batteries (RECHARGE)

 Introduction

1.  At the fortieth session PRBA and RECHARGE jointly submitted document ST/SG/AC.10/C.3/2011/41 proposing a new large packaging instruction for lithium cells and batteries.  There was general support for the proposal in principle, provided that only a single battery or battery assembly would be permitted in each large packaging, but a number of comments of detail were offered.  PRBA withdrew the proposal with a view to preparing a revised document taking account of the comments made by Sub-Committee members.

2.  Considerable discussion at the last session focused on the question of whether a large packaging packing instruction was necessary for batteries exceeding 12 kg and employing an impact-resistant outer casing since packing instruction P903 currently permits such batteries to be transported in strong outer packagings, in protective enclosures, on pallets or on other handling devices which are not subject to a 400 kg net mass limitation as prescribed for UN-tested and marked packagings under Chapter 6.1.  However, that the 400 kg net mass limit did not apply to such non-UN marked and certified packagings was not entirely clear.  In this regard, PRBA and RECHARGE note that a document on the Guiding Principles for packaging submitted to this session by the United Kingdom expert will address this issue, and clarify in the Guiding Principles that to the extent that the “P” packing instructions permit the use of certain packagings or packing methods that are not subject to the requirements of Chapter 6.1, such packagings and packing methods are not, therefore, subject to the mass or capacity limitations in Chapter 6.1. PRBA and RECHARGE welcome and support this important clarification. 

3.  At the same time, PRBA and RECHARGE continue to believe that a large packaging packing instruction remains essential to facilitate the safe transport of large lithium batteries not employing a strong, impact-resistant outer casing.  In addition, although eligible under packing instruction P903 for transport in non-UN-marked and certified packagings, if a consignor may elect to utilize a large packaging for the transport of a single large lithium battery employing a strong, impact-resistant outer casing, PRBA and RECHARGE believe this practice should be explicitly authorized by the Model Regulations.

Proposal

4.In consideration of the foregoing, PRBA and RECHARGE invite the Sub-Committee to consider the following proposal for a new large packaging packing instruction LP903 for the transport of a single lithium battery or battery assembly.

第四十一次会议

日内瓦, 2012年6月25日-7月4日
议程第4（d）项

电存储系统：大锂电池的包装

锂电池大包装的包装说明

由可充电电池协会(PRBA)和国际便携式可充电电池促进和管理协会(RECHARGE)提交

介绍

1.在第40次会议上，PRBA和RECHARGE联合提交了文件 ST/SG/AC.10/C.3/2011/41 提议为锂电池芯和电池建立一个 新的大包装的包装说明。如果在每个大包装中只允许装一个电池或电池组合体，大体上都支持这个提案，但是也有一些具体的意见。为了考虑分委员会成员的意见重新准备一份修订的文件，PRBA撤回了该提案。

2. 在上次会议上，相当多的讨论是关于对超过12kg的有抗撞击外壳的锂电池，大包装的包装说明是否有必要。因为目前的包装说明P903允许这类电池在坚固的外包装中、在有保护功能的外罩中、在货盘上或另外的操作设备上运输，没有受到6.1章中UN测试和标记的包装中规定的400公斤净重限制。然而，这400公斤净重限制不应用于非UN标记和认证的包装并不完全明确。在这一点上，PRBA和RECHARGE注意到英国专家提交至本次会议的一份关于包装指导原则的文件将说明这个问题，在指导原则中阐明包装说明“P”允许使用某些不受6.1章要求限制的包装和包装方法，这类包装和包装方法不受限于6.1章中的质量和容量的限制。PRBA和RECHARGE欢迎并支持这个重要的澄清。

3. 同时，PRBA和RECHARGE仍然相信大包装的包装说明还是能有助于没有坚固、抗撞击外壳的大电池的安全运输。另外，虽然不是UN标记和认证的包装按照包装说明P903是符合运输要求的，但是发货人可以选择使用一个大包装运输单个有坚固、抗撞击外壳的大型锂电池，PRBA和RECHARGE相信这也是规章范本明确允许的。

 提议

4. 综上所述，PRBA和RECHARGE邀请分委员会考虑下面的提议，要求建立一个新的大包装件的包装说明LP903 ，用于运输单个锂电池或电池组合体。
