laying down technical requirements for non-automatic weighing instruments
The Government orders pursuant to Section 22 of Act No. 22 / 1997 Coll., on Technical Requirements for Products and on the Amendment and Addition of Certain Acts, as amended by Act No. 71 / 2000 Coll. and Act No. 205 / 2002 Coll., ("the Act ') to implement Sections 11 (2), 12 and 13 of the Act:
(1) This Regulation lays down technical requirements for non-automatic weighing instruments in accordance with the law of the European Communities (1).
(2) For the purposes of this Regulation, non-automatic weighing instruments shall be regarded as non-automatic weighing instruments which are used to determine the mass of the body by the use of gravity on that body and which require intervention by the operator during the weighing process (hereinafter referred to as "scales'). The weights may also be used to determine other quantities, quantities, parameters or characteristics related to the mass.
(1) The determined products under Article 12 (1) of the Act are the scales used for:
(a) determination of weight for the purposes of trade;
(b) determination of weight for the calculation of fees, charges, taxes, premiums, fines, refunds, compensation or similar types of payment;
(c) determination of weight for the purpose of applying laws or regulations, giving expert advice in litigation;
(d) mass determination in health care when weighing patients for monitoring, diagnosis and treatment;
(e) determination of weight for the preparation of prescription drugs in pharmacies and determination of weight for analyses carried out in medical and pharmaceutical laboratories;
(f) determination of the price on the basis of weight for the purposes of direct sales to the public and preparation of pre-packaged products.
(2) The weighing instruments intended for the purposes referred to in paragraph 1 must meet the essential requirements set out in Annex 1 to this Regulation. Where instruments are subject to other government regulations laying down technical requirements for products and those government regulations provide for additional requirements not set out in Annex 1 to this Regulation, the instruments shall also comply with those requirements.
(3) Where instruments contain equipment or are linked to devices not intended for the purposes referred to in paragraph 1, the essential requirements for such equipment shall not apply.
(4) Compliance with a harmonised Czech technical standard, a designated standard or compliance with a foreign technical standard transposing a harmonised European standard in the Member States of the European Union shall be deemed to meet the technical requirements set out in Annex 1 to this Regulation.
(5) The weighing instruments intended for purposes other than those laid down in paragraph 1 are not specified products and shall not be considered as conformity, but shall be marked in accordance with point 2 of Annex 4 to this Regulation. These inscriptions shall be affixed in such a way that they are clearly visible, easily legible and unremovable. It shall be prohibited to affix to the weights marks which could be confused with the mark of conformity.
(1) The manufacturer shall ensure, prior to placing on the market, a conformity assessment (Section 12 (4) of the Act) with the essential requirements set out in Annex 1 to this Regulation, at his choice, by one of the following two procedures:
(a) by the EC type-examination referred to in point 1 of Annex No 2 to this Regulation and shall also ensure either:
1. EC declaration of conformity to the type (quality assurance) referred to in point 2 of Annex 2 to this Regulation; or
2. EC verification according to point 3 of Annex No 2 to this Regulation,
(b) EC verification of each individual product in accordance with point 4 of Annex 2 to this Regulation.
(2) The EC type-examination is not mandatory for instruments for which electronic devices are not used and in which a spring is not used to balance the load.
(3) The manufacturer shall place on the scales referred to in Article 2 (1) which comply with the requirements of this Regulation the CE marking (3). The CE marking and the particulars required under point 1 of Annex 4 to this Regulation shall be affixed to the instruments for which conformity has been established in such a way that they are clearly visible, easily legible and unremovable. It shall be prohibited to affix to the weights marks which could be confused with the CE marking.
(4) Where the instruments referred to in Article 2 (1) contain or are attached to equipment which is not the subject of conformity assessment, each of these devices shall be marked with a symbol of restricted use in accordance with point 3 of Annex 4 to this Regulation. The symbol of restricted use affixed to the device shall be clearly visible and unremovable.
(5) The manufacturer's activities referred to in paragraphs 1 and 4 and, if further specified in the Annexes to this Regulation, may be provided by his authorised representative.
The content of the technical documentation submitted by the manufacturer or importer to the authorised person is set out in Annex 3 to this Regulation.
For the assessment of the conformity of weighing instruments, authorisation (Article 11 of the Act) may be granted only to legal persons who fulfil the minimum conditions set out in Annex 5 to this Regulation.
Certificates and, where applicable, other documents issued under existing legislation and technical documentation shall remain valid for the period for which they were issued, unless they are amended or revoked under the conditions laid down by law.

ESSENTIAL REQUIREMENTS
Preliminary provisions
If the instruments are equipped with more than one indication or printing device intended for the purposes referred to in Article 2 (1) or are attached thereto, those devices which repeat the results of the weighing operation and which cannot affect the correct functioning of the weighing instrument 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 weighing instrument 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 consumer shall comply with the essential requirements.
METHOLOGICAL REQUIREMENTS
1. Weight units
The units used are legal units provided for by special legislation4), on the basis of which the following units and their multiples and parts may be used:

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. Weights having one weighing range divided into partial weighing ranges, each with a different value of the piece, one of which is automatically determined according to the applied rising and decreasing load, shall be considered as having a multiple-range weighting.
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:
with its verification part ei, e (i + 1) > ei
Maxi, with Maxr = Max
its lower limit of gravity Mini, with 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.
