2. (1) Subject to subsection (2), these Specifications apply to any non-automatic weighing device and to any equipment or accessory that is attached to the device or used in conjunction with it.

(2) A non-automatic weighing device that, before June 15, 1998, was approved under subsection 3(1) of the Weights and Measures Act or inspected under the terms of a previous enactment — or whose class, type or design was so approved —

• (a) is subject to the performance requirements set out in these Specifications; and

• (b) is not subject to any of the provisions of these Specifications relating to design, composition, construction or marking where the non-automatic weighing device meets the requirements that applied when its class, type or design was approved or, failing which, that applied to the device on its approval or inspection.

3. (1) Subject to subsections (2) and (3), the classes of non-automatic weighing devices are as set out in column 1 of the table to this subsection on the basis of the device’s accuracy, verification scale interval and number of verification scale intervals as set out in columns 2, 3 and 4, respectively, of that table.

Column 1	Column 2	Column 3		Column 4
		Verification scale interval (e)		Number of verification scale intervals
Class	Accuracy	International Units	Canadian Units	Minimum	Maximum
	Special	e	e	50 000	– – –
	High	0.001 g (0.005 carat)	0.00005 ounce (troy ounce)	100	100 000
		≤ e ≤	≤ e ≤
		0.05 g (0.2 carat)	0.002 ounce (troy ounce)
		e ≥ 0.1 g (0.5 carat)	e ≥ 0.005 ounce (troy ounce)	5 000	100 000
	Medium	0.1 g ≤ e ≤ 2 g	0.0002 pound (0.005 ounce)	100	10 000
			≤ e ≤
			0.005 pound (0.1 ounce)
		e ≥ 5 g	e ≥ 0.01 pound (0.2 ounce)	500	10 000
	Medium (high capacity devices)	e ≥ 2 kg	e ≥ 5 pounds	2 000	– – –
	Ordinary	e ≥ 5 g	e ≥ 0.01 pound (0.2 ounce)	100	1 200

(2) On-board weighing systems are limited to Classes , and .

(3) The verification scale interval of Class on-board weighing systems shall not be less than 5 g.
