The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Clock origin, case and movement construction and function | Clock origin, case and movement construction and function may include: clocks from all countries of manufacture clocks manufactured during the 19th and 20th Centuries clock cases made from timber, metal, natural stone and composite materials movement components made from brass and steel pendulum or balance oscillating systems timepiece only mechanisms motive force (e.g. mainspring or weight driven) gear train for transmitting of power escapement for release power oscillator for controlling the speed of release of power winding (e.g. by key) time setting (e.g. by key or direct movement of hands) |
