Executive summary for the EC (not part of this legislation)  
‘Serving measures’  may be placed on the market in the Czech Republic for use in measuring with 
protection of public interest significance in the areas of consumer protection, contractual relations, 
imposition of sanctions, fees, tariffs and taxes, health protection, environmental protection, 
occupational safety, or the protection of other public interests protected by special legislation  in 
accordance with Directive 2014/32/EU (MID). The requirements of this legislation do not apply to 
measuring instruments placed on the mar ket in the Czech Republic for anything other than the above 
purposes.

The procedure in this chapter applies to the examination of a measuring instrument pursuant to § 11a of

8.1   Maximum permissible errors (MPE)  
The maximum permissible errors applicable when examining capacity serving measures pursuant to 
§ 11a of the Metrology Act are provided in Table  1.

8.1   Tests  
8.2.1  Reference conditions 
The reference temperature for measurement of capacity is 20  °C. 
Ambient temperature is (20  ± 5) °C. 
The temperature of the water used for testing is (20 ± 5)  °C. 
Position for correct indication: the instrument is free standing on a level surface.  
8.2.2  Test procedure  
Tests to assess the conformity of capacity serving measures consist of the following:  
a) visual inspection;  
b) capacity accuracy test.  General Measure No  0111- OOP -C099- 19 
4 8.2.2.1  Visual inspection  
The purpose of the visual inspection is to ascertain whet her the measuring instrument is:  
 not mechanically damaged;  
 made of material which is sufficiently rigid and dimensionally stable to maintain capacity within 
the MPE;  
 appropriately marked (capacity markings in legal units; designation of the manufacturer; the CE 
marking and the supplementary metrology marking, including the identification number of the 
notified body);  
 no further tests are performed on a measure that has not met the visual inspection requirements.  
8.2.2.2   Accuracy test  
A capacity accuracy test of the capacity serving measure using a standard capacity serving measure:  
 The capacity accuracy test consists of determining the actual volume of water in the measure and comparing it with the nominal capacity. 
 The tested measure shall be cleaned, wetted and left to drain for a waiting period of 10 s. After 
the waiting period has elapsed, the remaining drops are removed from the rim of the measure by 
tapping it against the edge of the container in which the drained water is capture d. 
 A wetted and drained standard capacity serving measure with a capacity corresponding to that of 
the tested measure is placed on a horizontal plate and filled with water so that the upper edge of 
the filling mark is tangent to the lowest point of the meniscus when the viewing direction is in the 
same plane. If a standard measure with a cut -off neck and ground cut surface is used, after filling 
the measure, the meniscus is adjusted by trimming the level using a ground- glass plate. If relevant, 
when using a st andard measure, the error of the standard measure at the given value (according 
to the calibration sheet of the standard measure) is taken into consideration.  
 The content of the standard capacity serving measure is poured into the tested measure placed o n 
a horizontal plate. After the water no longer flows continuously, wait 10 seconds for the water to 
drip out.  
 The actual volume of the tested measure is determined using a previously wetted graduated pipette 
or burette by removing or adding the amount of water necessary for the upper edge of the filling 
mark on the tested measure to be tangent to the lowest meniscus when the viewing direction is in 
the same plane. The amount of water thus added or removed represents the error Δ. 
 If two, or a maximum of  three, capacities are marked on the measure, the test is performed for 
both marked capacities.  
8.2.2.3  Assessment of the accuracy test  
Assessment of the capacity accuracy test on the capacity serving measure using a standard capacity 
serving measure:  
The relative error in the capacity of the tested capacity serving measure is calculated using the following 
equation:  
𝛿𝛿=�∆
𝑉𝑉𝑗𝑗𝑗𝑗�.100    % , (1) 
where  Δ ......... is the error in the capacity of the capacity serving measure measured according to 8.2.2.2 
in ml;  
Vjm ....... is the  nominal capacity of the standard measure (identical with the nominal capacity of 
the tested measure) in ml.  
The determined errors of the tested measure shall not exceed the relevant maximum permissible errors 
specified in Chapter  8.1, Table  1. General Measure No  0111- OOP -C099- 19 
5 9   Notifie d standards  
For the purposes of specifying the metrological and technical requirements for measuring instruments 
and specifying the testing methods for their type approval and verification arising from this general 
measure, the CMI shall notify Czech technical standar ds, other technical standards or technical 
documents of international or foreign organisations, or other technical documents containing more detailed technical requirements (hereinafter referred to as ‘notified standards’). The CMI shall publish 
a list of these notified standards attached to the relevant measures, together with the general measure, in 
a manner accessible to the public (at www.cmi.cz
). 
Compliance with notified standards or parts thereof is considered, to the extent and under the conditions 
stipulated by a general measure, to be compliance with the requirements stipulated by this measure to 
which these standards or parts thereof apply.  
Compliance with notified standards is one way of demonstrating compliance with the requirements. 
These requirements may also be met by using another technical solution guaranteeing an equivalent or 
higher level of protection of legitimate interests.
