物品中物质导则里面,6.2关于有意释放,有这样一段话:The intended release of substances as such or in preparations from an article normally applies to an accessory function of an article. In contrast, if the main function of an object is to release substances or preparations, as it is the case e.g. for pens, then the object is in most cases a “substance /preparation in a special container / on a special carrier material” and not an article with an intended release (c.f. Section 3.3.2). 大致是说有意释放是为了实现物品的附加功能,而象钢笔这样的,释放是为了实现主要功能,就不能作为有意释放,只能算是特殊容器中物质/配制品/特殊传输物质. 在3.3中,说温度计是物品.(因为其中的液体不是为了释放才实现功能,而是打破后可以释放).
