附件 XVII 第 18(a) 条中有关古董气压计的例外情况应如何解释？

How should derogation in entry 18(a) of Annex XVII related to Antique Barometers be interpreted?

根据第18(a)条，古董测量仪器的定义是指截至2007年10月3日已超过50年。根据第3款，古董测量仪器不受此限制。这些古董测量仪器的维修和保养活动也不受此限制。立法者授予古董测量仪器豁免的意图是，由于其文化和/或历史价值，其贸易应继续进行（第2007/51/EC号指令，序言第4号）。因此，这些仪器应继续进行维修，以保持其文化和/或历史价值。古董测量仪器，例如包含两根水银柱（其中一根为温度计）的气压计，被认为属于第3款的例外情况，因此应继续进行维修。如果维修或更换水银柱属于维修服务的一部分，并且能够保留仪器的文化和/或历史价值，则可以进行维修或更换。专业人士可以购买用于古董测量仪器维修和保养活动的含汞测量仪器。

Under 18(a) antiques measuring devices are defined as more than 50 years old on 3 October 2007. Under paragraph 3 antique measuring devices are exempted from the restriction. Repairing and maintenance activities for these antique measuring devices are also exempted for the restriction. The intention of the legislator in granting an exemption for antique measuring devices is that their trade should continue (Directive 2007/51/EC, Recital No 4) due to their cultural and/or historical value. Therefore these instruments should continue to be serviced in order to keep their cultural and/or historical value. Antique measuring devices such as barometers containing two columns of mercury which one consists of a thermometer are considered falling within the derogation of paragraph 3 and therefore they should continue to be serviced. The columns can be repaired or replaced if these activities are part of the maintenance and repair services and preserve the cultural and/or historical value of the instrument. Professionals may buy measuring devices containing mercury if they are destined for the repair and maintenance activities of antique measuring devices.
