Annex No 1 to Government Decree No 293 / 2000 Coll.
ESSENTIAL REQUIREMENTS
The essential requirements shall meet the scales referred to in Paragraph 2 (1) (a).
Preliminary provisions
If the instruments are equipped with more than one indicator or printing device used for the applications contained in or attached to paragraph 2 (a) of Section 2, then those devices which repeat the results of the weighing operation and which are not capable of affecting the correct functioning of the scales shall not be subject to the essential requirements provided that the weighing results are printed or recorded correctly and unremovable by any part of the scales which meets the essential requirements and are accessible to both parties involved in the measurement. However, in the case of weighing instruments used for direct sale to the public, the display and printing equipment for the seller and the customer shall comply with the essential requirements.
METHOLOGICAL REQUIREMENTS
1. Weight units
The units in use are the legal units provided for in the special Regulation (6) on the basis of which the following units and their multiples and parts are permitted:
- SI units: kilogram, microgram, milligram, gram, tonne,
- British units: pound, ounce (avoirdupois), trojan ounce,
- other units other than SI: metric carat in the case of weighing precious stones.
For weighing instruments using the abovementioned British units of mass, the relevant essential requirements are converted into British units by simple interpolation.
2. Precision classes
2.1 The following accuracy classes are defined:
I special,
II high,
III Medium,
IV common.
The specification of these classes is given in Table 1.
TABLE 1
Accuracy classes
| třída | ověřovací dílek (e) | dolní mez váživosti (Min) | počet ověřovacích dílků n = Max/e | ||
|---|---|---|---|---|---|

| I | 0,001 | g ≤ e | 100 e | 50 000 | - |
| II | 0,001 0,1 | g ≤ e ≤ 0,05 g g ≤ e | 20 e 50 e | 100 5 000 | 100 000 100 000 |
| III | 0,1 5 | g ≤ e ≤ 2 g g ≤ e | 20 e 20 e | 100 500 | 10 000 10 000 |
| IV | 5 | g ≤ e | 10 e | 100 | 1 000 |
The lower limit of gravity is reduced to 5e for scales in classes II and III determining the transport tariff.
2.2. Scale sections
2.2.1 The actual scale part (d) and the verification part (e) are in the form of:
1 x 10k, 2 x 10k or 5 x 10k units,
k is an integer or zero.
2.2.2. For all weighing instruments except weighing instruments with auxiliary indicating equipment:
d = e.
2.2.3. The following conditions shall apply to instruments with auxiliary indicators:
e = 1 x 10k g
d < e ≤ 10 d
except for tier I weights with d < 10- 4g for which e = 10- 3g.
3. Classification
3.1. Weights with one weighing range
Balances fitted with auxiliary indicators belong to the class I or Class II. For these weights, for these two precision classes, the lower limit of gravity shall be determined from the third column of Table 1 by replacing the verification panel (e) with the actual section of the scale (d).
If d < 10- 4g, the upper limit of gravity may be in the class I lower than 50,000 e.
3.2. Weights with multiple ranges
Multiple weighing ranges are permitted provided they are clearly marked on the scales. Each individual weighing range is classified according to point 3.1. Where weighing ranges belong to different precision classes, the weights shall meet the strictest of the requirements applicable to the precision classes to which those weighting ranges fall.
3.3. Weights with multiple ranges
3.3.1 One-scale scales may have several partial weighing ranges (multiple-scale weights).
3.3.2 Weights with multiple ranges shall not be equipped with an auxiliary indicator device.
3.3.2. Each partial weighing range for multi-scale weighing instruments is defined as follows:
| svým ověřovacím dílkem ei, | přičemž e(i+1) > ei |
| svou horní mezí váživosti Maxi, | přičemž Maxr = Max |
| svou dolní mezí váživosti Mini, | přičemž Mini = Max(i-1) a Min1 = Min |
where:
| i = 1,2, | r, |
i = number of partial weighing range,
r = total number of partial weighing ranges.
All weightings refer to the net load, regardless of the value of the used tar.
3.3.3. The sub-weighting ranges are classified according to Table 2. All partial weighing ranges fall within the same class of accuracy, which is the class of balance accuracy.
