Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labelling of Chemicals
Sub-Committee of Experts on the Transport of Dangerous Goods
Forty-first Session
Geneva, 25 June– 4 July 2012
Item 3 (a) of the provisional agenda
Listing, classification and packing:
proposals of amendments to the list of dangerous goods of Chapter 3.2
Proposal for a new UN number and special provision for a new type of confetti-shooters
Transmitted by the expert from Germany
Background
1. In document ST/SG/AC.10/C.3/2010/64, the expert from Germanypresented a proposal to assign a new UN number to articles containing a small gas receptacle and intended to function as confetti-shooters. A revised document was presented to the Sub‑Committee at its fortieth session in December 2011 (see informal document SCETDG/40/INF.23).
2. Some support was expressed to include provisions on such articles in the Model Regulations and the experts provided detailed comments during the discussion and afterwards in writing.
3. The proposal of amendments is reproduced in annex I to this document. Annex II contains the same proposed amendments and shows the changes brought to the last discussed proposal in informal document SCETDG/40/INF.23.
4. As several comments referred to the name and description, two options are presented for the entry in column 2:
Option 1: “ARTICLES, CONTAINING SMALL GAS RECEPTACLES with non-flammable gas, intended to function as confetti-shooters.”.
Option 2: “CONFETTI-SHOOTERS, articles containing small pressure receptacles with non-flammable gas.”
There are also confetti-shooters functioning with class 1 substances which are transported under the entry UN 0432 ARTICLES, PYROTECHNIC for technical purposes. Therefore option 1 might be preferable to avoid any confusion with the 1.4S articles.
5. The Sub-Committee is invited to discuss the proposal and decide on its adoption as appropriate.

(b) Add a new Special Provision 3XX in Chapter 3.3:
“3XX (1) [Articles, containing small gas receptacles, intended to function as confetti-shooters,] [Confetti-Shooters are articles, containing small pressure pressurized receptacles, intended to function as confetti-shooters. They] shall comply with the following requirements:
(a) The pressure receptacle shall be filled with compressed air or compressed nitrogen only;
(b) The water capacity of the pressure receptacle shall not exceed 0.5 litres and the working pressure shall not exceed 25 bar at 20 °C;
(c) The minimum burst pressure of the pressure receptacle shall be at least four times the pressure of the gas at 20 °C;
(d) Each article shall be manufactured in such a way that unintentional firing or release is avoided under normal conditions of handling, packing, transport and use. This may be fulfilled by an additional locking device linked to the usual activator;
(e) Each article shall be manufactured in such a way to prevent the pressure receptacle from rocketing backwards through the bottom of the article and preventing the metal flap or fragments of the pressure receptacle from catapulting during the activation of the article;
(f) Each pressure receptacle shall be manufactured from material which will not fragment upon rupture;
(g) The design type of the article shall be subjected to a fire test . For this test, the provisions of paragraphs 16.6.1.2, 16.6.1.3.1 to 16.6.1.3.6, 16.6.1.3.7 b) and 16.6.1.3.8 of the UN Manual of Tests and Criteria shall be applied. It shall be demonstrated that the article relieves its pressure by means of a fire degradable seal or other pressure relief device, in such a way that the pressure receptacle will not fragment and that the article or fragments do not rocket more than 10 metres; and
(h) The design type of the article shall be subjected to a single package test. For this test, the provisions of section 16.7.1 of the Manual of Tests and Criteria shall be applied with the following modifications: instead of a detonator or igniter according to 16.7.1.2 a) and b) and 16.7.1.3.2, a stimulating mechanism shall be used to initiate one confetti shooter in the middle of the packaging to function; instead of 16.7.1.3.4 first sentence the donor article should be initiated and observations made on the following: denting or perforation of the witness plate beneath the package, initiation of adjacent shooters, disruption of the package causing projection of the contents or fragments of the article or full perforation of the packaging by a projection; all other provisions of 16.7.1.3.4 shall be applied; 16.7.1.4. b) shall not be applied and c) should be understood as meaning the content of the shooter or its fragments; 16.7.1.5 is not relevant for confetti-shooters. There shall be no hazardous effects outside the package from accidental activation of one article. Evidence of hazardous effects outside the package includes the disruption of the package, metal fragments or the pressure receptacle passing through the packaging.
(i) Each article shall be marked with the name or another identification mark of the manufacturer and the date (YYYY-MM-DD) of manufacture.
2. The manufacturer shall produce technical documentation of the design type, manufacture as well as the tests and their results. The manufacturer shall apply procedures to ensure that shooters produced in series are made of good quality, conform to the design type and are able to meet the requirements in (1). The manufacturer shall provide such information to the Competent Authority on request.
3. Articles conforming to the requirements in (1) and (2) are not subject to further requirements of these Regulations if packed according to P 003 in packagings not exceeding 30 kg gross mass.”

第四十一次会议
日内瓦, 2012年6月25日-7月4日
议程第3(a)项
列表、分类和包装
对修订3.2章危险货物列表的提案
新型五彩纸屑发射器的新UN号和特殊条款提案
由德国专家提交
背景
1. 在文件ST/SG/AC.10/C.3/2010/64中，来自德国的专家提出了关于给予一种含有小型气体容器且用作五彩纸屑发射器的物品一个新的UN编号的提议。在2011年12月份的第40次会议上又递交了修订文件（见INF文件SCETDG/40/INF.23）。
2. 一些支持者同意在规章范本中增加对这类物品的规定，专家们在讨论和之后的编写过程中提供了详细的评论。
3. 本提案的附件I中复制了所提议进行的修订，附件II包含了相同的所提议进行的修订以及对上次INF文件SCETDG/40/INF.23中讨论的提案的变化。
4. 由于对名称和描述有许多意见，现对第2栏的条目提出以下两个选择：
选择1：“物品，含有小型气体压力容器，含非易燃气体，用作五彩纸屑发射器”。
选择2：“五彩纸屑发射器，物品包含有非易燃气体的小型压力容器”。
五彩纸屑发射器也会有为了技术目的，按照第1类物质以UN0432（专用烟火制品）条目进行运输的情况，因此，选择1可能更合适，以避免与1.4S物品发生混淆。
5. 希望分委会讨论这个提议并且决定是否采纳。

(a) 在3.3章中增加一个新特殊规定3XX
“3XX (1) [物品，含有小型气体压力容器，含非易燃气体，用作五彩纸屑发射器]，[五彩纸屑发射器，物品包含有非易燃气体的小型压力容器]，应符合下列要求：
(a) 压力容器只能填充压缩空气或压缩氮气；
(b) 压力容器中的水容量不得超过0.5升，且20℃时的工作压力不得超过25bar；
(c) 20℃时压力容器的最小爆破压力至少为气体压力的四倍；
(d) 每个物品的制造时应避免在正常的处置、包装、运输和使用过程中意外的着火或释放。这可以通过与通常的激活器相连的附加锁定装置来实现；
(e) 每个物品在制造时应防止压力容器向后发射突破物品底部，防止在物品激活过程中压力容器的金属盖片或碎片的弹射；
(f) 每个压力容器应该由爆裂时不会产生碎片的材料制成；
(g) 物品的设计类型应经过一个火烧测试。对于这项测试，应遵守联合国试验和标准手册中16.6.1.2, 16.6.1.3.1至16.6.1.3.6, 16.6.1.3.7 b) 以及16.6.1.3.8段落的规定。应当证明此物品通过减火垫或其他释压装置来释放压力，并保证压力容器不会碎裂，物品或者碎片射出距离不会超过10米；和
(h) 物品的设计类型应经过一项单个包装件测试。对于这项测试，应遵守联合国试验和标准手册中16.7.1的规定，但要做如下修正：应使用激发机理以引发包装件中间的一个五彩纸屑发射器使其作用，以此来代替16.7.1.2 a) 和 b) 以及 16.7.1.3.2中所述的雷管或点火器；对 16.7.1.3.4中第一句话修改为：引爆施主物品并作以下观察：包装件下的验证板凹陷或穿孔，激发周围的发射器，包装件破裂造成物品的内装物或碎片抛出，或抛出物造成容器完全穿孔。应遵守16.7.1.3.4中的其他规定；16.7.1.4. b)不适用，同时c)应理解为发射器的内装物或它的碎片；16.7.1.5与五彩纸屑发射器不相关。意外激发一个物品或其内容物时，包装外部应没有危险。包装外部存在危险迹象的依据包括包装的破裂，穿过包装的金属碎片或容器。
(i) 每个物品应有名称或其他有关制造商以及生产日期(YYYY-MM-DD)的标识。
2. 制造商应提供设计类型、生产和测试及其结果的技术文件。制造商还应采用程序以确保一系列生产的发射器都有好的品质、符合设计类型并能够满足（1）中要求。当主管当局要求时，制造商应提供这些信息。
3. 满足（1）和（2）要求的物品，如果根据P 003其在包装中的毛重不超过30kg，则这些物品不受本规章其他规定的限制。”
