3. DEFINITIONS: (WORDS DEFINED ARE ITALICIZED AND BOLDED ONCE PER SECTION).
·定义：（被定义的词在每段用粗黑斜体标示一次）
Experimental Sets: Collection of electric or electronic components intended to be
assembled in various combinations. The main aim of an experimental set is to facilitate
the acquiring of knowledge by experiment and research, it is not intended to create a toy
or equipment for practical use. Experimental sets may include mechanical parts and the
aim of the set may be to demonstrate physical, electrical, or mechanical
phenomena/functions.
·实验组件：供装配成各类组合的电子或电动元件的集合, 其主要目的是通过实验及研究
来
获取知识, 而不是为了组装实用型玩具或设备。

4. PERFORMANCE REQUIREMENTS（测试要求）
4.1. Wireways must be smooth and free from sharp edges and sharp point.
电线必须光滑不能有尖点和利边。

4.2. Cords and wires must be protected so that they do not come into contact with burs,
cooling fins or similar edges, which may cause damage to their insulation.
电线/电缆不准与冷却板，锋利边缘等接触，以免造成对其绝缘层的破坏。

4.3. Holes in metal through which the wire and cords pass must have smooth well-rounded
surfaces or be provided with bushings.
电线/电缆从金属板上穿过时，穿过的孔必须光滑及有圆角或加线扣保护。

4.4. Cords and wires must be effectively prevented from coming into contact with moving parts.
电线/电缆须防止其进入移动部件而导致破坏绝缘层。

4.5. Bare wiring and heating elements must be rigid and fixed so that, during play, creepage
distance and clearance can not be reduced the value listed in TX-Q04-W3273, Creepage
& clearance Distance.
裸线或发热元件须良好固定，在使用过程中，其爬距及间距不会发生改变以致小于TX-
Q04-W3273，爬距和间距的规定值。
