Annex to Decree No 31 / 2002 Coll.
1. DEFINITION OF MEASUREMENT
1.1. Spirits are glass gauges which indicate a fraction or concentration of alcohol by weight in a mixture of water and ethanol. These measuring instruments are described as mass alcohol meters or volume alcohol meters, as measured. The density meters for alcohol are glass gauges designed to measure the density of the mixture of water and ethanol.
1.2 The measuring instruments defined in this decree are equipped with a scale at a reference temperature of 20 ° C, in accordance with the values calculated in accordance with the specific legislation3).
1.3 These gauges are equipped with a reading scale in the plane of the free horizontal surface of the liquid.
2. DESCRIPTION OF MEASUREMENT
2.1. Liquids and alcohol densifiers are glass gauges which are made up of a cylindrical body, the lower part of which is conical or semi-spherical, so as not to hold any air bubbles and hollow cylindrical stop drawn to the upper part of the body; Her top end is sealed.
2.2 The entire outer surface of each measuring instrument shall be symmetrical around the main axis. The cross-section must show no sudden change.
2.3 The lower part of the body shall contain a loading material designed to balance the mass of the measuring instrument.
2.4 The stop sign shall be provided with a scale on the cylindrical support well fixed to the inside of the stop sign.
3. CONSTRUCTION PRINCIPLES
3.1 The glass used for the manufacture of measuring instruments shall be transparent and free of any defects which may adversely affect the reading on the scale. The glass shall have a volume expansion coefficient (25 ± 2) · 10-6 ° C-1.
3.2 The load material shall be fixed at the bottom of the gauge. After keeping the modified gauge horizontal at 80 ° C for 1 hour and then cooling in this position, it shall be sown so that its vertical axis deviates by 1 degree and 30 minutes when immersed.
4.
4.1 No gauge shall have more than one scale of the type referred to in paragraph 4.5 or 4.6.
4.2 The scales and inscriptions shall be marked on a support having a smooth and matte surface. This support shall be well fixed to the position at the stop sign and reference marks should be made so that each shift of the scale and its support relative to the stop sign is obvious. The supports, scales and inscriptions shall show no traces of deformation, discoloration or incineration due to exposure to a temperature of 70 ° C for 24 hours.
4.3. The scale marks shall be:
- placed in planes perpendicular to the measuring axis,
- black and marked clearly and indelibly; outside the range of the rated scale, the scale marks may be of different colour,
- fine and aligned and of the same width not exceeding 0,2 mm.
4.4 The length of the short scale marks shall be at least one fifth, the length of the medium scale marks at least one third and the length of the long scale marks at least half of the stop sign circumference.
4.5. Limemeters shall have nominal scales of division by weight or volume of alcohol. Their scope shall not exceed 10% by volume or weight of alcohol. The value of the scale piece shall be 0,1%. Each scale shall include between 5 and 10 additional scale marks at the upper and lower limits of the nominal range.
4.6 The density meters for alcohol shall be rated scales divided in kg / m3. It shall cover a range not exceeding 20 kg / m3. The value of the scale sections shall be 0,2 kg / m3. Each scale shall comprise 5 to 10 additional sections at the upper and lower limits of the nominal range. However, the scale shall not exceed 1000 kg / m3.
5. DIFFERENCE AND NUMBER OF STUDIES
5.1 Each tenth mark on the scale, starting from one end of the nominal scale, shall be long. The medium-long mark shall be between each subsequent pair of long marks and four short marks between each long mark and the nearest medium-long mark. Long marks shall be numbered.
5.2 For alcohol densimeters, each fifth mark shall be long, starting from one end of the nominal scale. There shall be four short marks between two consecutive long marks. Only the fifth and tenth marks must be numbered.
5.3. The marks identifying the limits of the nominal scale shall be described by full figures. In the case of alcohol densimeters, other scale sections may be marked with abbreviated figures e.g. only numbers after decimal point.
6. GENERAL CLASSIFICATION AND BASIC DIMENSIONS OF MEASUREMENT
6.1 The gauges shall be in one of the following accuracy classes:
| - Třída I: | Délka dílku stupnice musí být nejméně 1,5 mm. Měřidla v této třídě nesmějí mít teploměr. | |||
