METHODS OF IDENTIFYING ILLEGAL GAINS BY VIOLATING MEASUREMENT LAWS

Article 8. Illegal gain

Illegal gain is the money collected by violating measurement laws in one of the following cases:

...

...

...

2. Illegal gain from carrying measurement during the provision of goods and services that the variance of quantity exceeds the tolerance according to the technical requirements of measurement that they announced or provided by the Minister of Science and Technology;

Article 9. Determining the time of violating measurement laws

1. The period of violating measurement laws is the period from the time of starting to commit the violation until the time such violation is discovered by competent State agencies.

2. The time of starting to commit the violation of measurement laws to make illegal gain as prescribed in Clause 1 Article 8 of this Decree is the closest time with the time when competent State agencies discover the violation, and determined according to one of the following times:

a) The time of starting to sell the pre-packed goods written on the contract, financial invoice, or the customs declaration sheet with customs clearance certification;

b) The time of the latest metrological inspection carried out by competent agencies, regarding the quantity of the pre-packed goods.

3. The time of starting to commit the violation of measurement laws to make illegal gain prescribed in Clause 2 Article 8 of this Decree is the closest time with the time when competent State agencies discover the violation, and determined according to one of the following times:

a) The time of the latest metrological inspection carried out by competent agencies;.

b) The time of the latest inspection of the measurement instruments;

...

...

...

Article 10. Determination of the quantity of goods and services measured incorrectly

1. The quantitative variation of pre-packed goods equals the number of pre-packed units sold during the period of violating measurement laws, multiplied by the missing amount.

The missing amount is calculated by subtracting the average value from the permissible value.

2. The quantitative variation of goods and services equals the total amount of goods and services provided sold during the period of violating measurement laws, multiplied by the missing or excessive amount compared to the technical requirements of measurement.

The missing or abundant amount compared to the technical requirements of measurement is the variation detected during the inspection minus the tolerance of the corresponding measurement results.

Article 11. Prices of goods and services for calculating the illegal gain

1. Prices of pre-packed goods and other goods and services that have been sold and provided after measurement shall be determined in accordance with the following priority:

a) The actual prices, the posted prices, or the prices written on the contract, the sale invoice, or the import declaration;

b) The market prices of the goods and services where the violation is discovered according to the price list of the local financial agency;

...

...

...

2. The price of pre-packed goods and other goods and services that have been sold and provided after measurement is the arithmetic mean of the price at the time of starting to commit the violation, and the price at the time of discovering the violation.

Article 12. Illegal gain

The illegal gain made by committing violations of measurement laws equal the quantitative variation of goods and services prescribed in Article 10 multiplied by the price determined as prescribed in Article 11 of this Decree.

ANNEX V

EXPRESSION OF LEGAL UNITS

(Promulgated together with the Government's Decree No. 86/2012/NĐ-CP dated October 19th 2012)

The legal units of measurement must be express as follows:

1. The name and symbol of a unit must be expressed in the same manner (using both names or both symbols).

Example: kilometer per hour or km/h (not kilometer per h, kilometer/h, or km/hour.

...

...

...

Example: meter, second, ampere, kelvin, pascal…

3. The unit symbols must be written in lower case and upright, except for liter (L)

Example: m, s...

The first letter of the names derived from proper names must be originated

Example: A, K, Pa…

4. Do not add any elements or other symbols to the symbols of legal units of measurement.

Example: do not use W_e as a symbol of the unit of electric power (the proper symbol is W).

5. Use a middle dot (•)  or a space when expressing a multiplication of two or more units of measurement; the gap between the  (•) and the preceding symbol must equal a space.

Example: the unit of resistance power being meter kelvin per watt must be abbreviated to:

...

...

...

6. Use a horizontal line (–) or a slant (/) or negative power when expressing a division of two or more units.

Example: the symbol of meter per second is or  m/s or m • s^-^1

If there are two or more units after a slant, they must be put in round brackets or converted into a multiplication of negative power. Do not use multiple slants in a symbol of a unit of measurement.

Example: J/(kg • K) or J • kg^-^1 • K^-^1 (not J/kg/K)

7. When expressing a value of a quantity, the symbol must be placed behind the number, these two parts must be separated by a space.

Example:

22 m (not 22m or 22  m);

31.154 m (not 31 m 15 cm 4 mm).

Notes 1: when expressing a unit of temperature in degree Celsius, there must be no space between the symbol of degree (°)  and the symbol of Celsius (C).

...

...

...

Notes 2: when expressing a unit of flat angle in ° (degree); ' (minute); " (second), there must be no space between the number and the symbol (°); ('); (").

Example: 15°20'30" (not 15 °20 '30 " or 15 ° 20 ' 30 ").

Notes 3: When expressing a value of quantity in a calculation, the unit symbols must comes with each number or be placed in a pair of round brackets for all numbers of the calculation.

Example: 12 m - 10 m = 2 m or (12-10) m (not 12 m - 10 = 2 m or 12 - 10 m = 2 m).

12 m x 12 m x 12 m or (12 x 12 x 12) m (not 12 x 12 x 12 m)

23 °C ± 2 °C or (23 ± 2) °C (not 23 ± 2 °C or 23 °C ± 2)

Notes 4:  Express the decimal of a quantity using a comma (,) not a dot (.)

Example: 245,12 mm (not 245.12 mm).
