To control the saving of the packaging and the transport tariffs for compliance with the standard of the party, select the vibration in the communication indicated in Table 4. 5. Vidbir one of the transport tariffs should be carried out by the method of vipadny vibration.


Table 4 - Vibrating ratio and indicators for controlling the quality of packaging and marking of transport rates

6.4 The party will be accepted, if the number of transport tariff units is from the vibrant, but it will not be reported to the recipients of the shipping rate, less than the appropriate number (Table 4).

6.5 The party does not accept, as long as the number of single transport tariffs from the vibrating, does not tell them how to pack and label, more or less the defect number, and to carry out repeated control on the same control of the transport.

6.6 In case of unsatisfactory results of repeated control of the quality of the packaging and of the transport tariff, the entire batch of sodium chloride is discarded.

7.1 Change of sodium nitrate samples

7.1.1 For folding a single sample of sodium citrate from rіznih mісць Skin unit of packaging in vibrating select points of the sample behind an additional sample of a sample (probe) or a metal tube, prepared from the material, but does not react with the product, and does not irritate any less on the glybin. Masa of the point test is guilty of buty close to 200 g.

When a combined sample of sodium chloride is folded, the number of point samples from the skin unit of the transport tariff, included before the vibration, is the same. Sample the points at once in a dry, clean glass and gently stir.

Masa ob'єdnanoi probi is guilty butti not less than 500 m

7.1.2 Obtained a sample of vikoristovoyt for the value of the viscous eye, organoleptic and physical and chemical indicators, in addition to toxic elements in sodium citrate.

We heat the product with wooden planks with beveled edges, weld it from the two opposite sides to the middle so that the roller is set. The product from the ends of the roller can also be squeezed into the middle of the table and once again be pulled out with a ball from 1.0 to 1.5 cm at the side of the square and by a bar diagonally to the chotiri of the tricycle. Two of the protagonists try to pull out, and the other two have lost their way, override, and again go to the chotiri tricytes. The operation is repeated until quiet times, as long as the sample is not reached until 500 m

7.2.3 Prepared, the sample should be divided into two parts and kept clean, dry and closed by the cans, one of which should be sealed, sealed and used for repeated vials in the event of a breakdown. A part of the common trial is taken until the end of the term of implementation.

Another part of the common test is vikorist for the appearance of a new eye, organoleptic and physical and chemical indicators, instead of toxic elements in sodium citrate.

7.11.1 Prepare your inventory, materials, reagents

Vagi laboratory in accordance with GOST 24104 with a boundary absolute loss of a single dose ± 0.001 g.
GOST 25336 with concentrated acidic acid in accordance with GOST 4204 of chemically pure grade, analytical grade for water-based calcium chloride according to GOST 450.

7.11.2 Carrying out vimiryuvan

Open the glass cup and heat the glass to a temperature of (180 ± 2) ° C to the drying shafu and turn it for 30 min. Record the indicated value in precision up to the third decimal place.

In the prepared glass, take a sample of sodium nitrate (1,200 ± 0.001) g, poured along the bottom with a small ball to the glass.

Open the glass with the product and place the glass of the glass in a drying shafu and vitrify at temperatures (180 ± 2) ° С for at least 3 years.

We'll drink a glass, close it with a crock, put it in an exsiccator, cool it down and read it up to the third decimal place.

Visusuvannya until the end of the day should be carried out until a quiet feast, as long as the results are not overridden by two results 0.001 r

7.11.3 Respect to spend a very short hour to hang out.

7.11.4 Processing of results

Massovu part of Vologa in 5.5-aqueous sodium citrate,%, calculated according to the formula

de - the mass of a glass with a crush and an analyzed breakdown of the product before hanging, g;

- the weight of a glass with a crush and an analyzed breakdown of the product, g;

- the weight of a glass with a kryshka, g;

100 - performance overhaul to the result of the analysis in the frame.

The calculation shall be carried out to another decimal place with the offensive rounding up to the first decimal place.

7.11.5 For the result of vimiryuvan, take the arithmetic mean of the results in two parallel values, rounded up to the first decimal place.

The importance of the results in vimiryuvan (acceptable divergence between the results of two parallel vimiryuvans) of the mass part of the vologue is not guilty of changing 0.1% abs.

The verification of the results in the mass part of the population is not guilty of changing the 0.5% abs.

Between absolute deviations in the range of - ± 0.5% abs.

Sodium citric acid is in accordance with the standard, although the mass part of the Vologda does not overtake 30.0%.

7.14.2 Carrying out vimiryuvan

The net weight of sodium monohydrate in one mouse will increase the amount of gross weight of the skin mouse taken from the vibrator, and the weight of the mouse. Record the results with exactness to an integer number.

7.14.3 Processing of results

Net mass of sodium monochromatic in a cup, kg, calculated according to the formula

de - gross weight of a zazhenny mіshka, kg;

- weight of a bear, calculated as a difference in gross weight and net weight, assigned to a label, kg.

For the residual result, you can take the average arithmetic value of the results in the amount of mice, which should be entered before vibrating.

The output of the net weight of sodium monoxide,%, is calculated according to the formula

de - net weight of sodium monohydrate, calculated according to the formula (4), kg;

- net weight of sodium lime, assigned to the label, kg;

100 - efficiency of transferring the net weight to the frame.

Sodium citric acid is in accordance with the standard, which is negatively absorbed in the skin packaging and does not change 1%.

Allowed for the storage of these substances in the form of additional possession of metrological and technical characteristics not lower than and reagents for quality not lower than the values ​​in 7.3.1, 7.4.1, 7.5.1, 7.6.1, 7.9.1, 7.10.1, 7.11.1 ...

8 Transport and transportation

8.2 Sodium citric acid is guilty of taking over in super-dry conditions at temperatures from minus 20 ° C to plus 35 ° C, and no more than 70% of the total moisture content is at least 70%.

8.3 The virobnik guarantees the conformity of sodium nitrate to the standard given to the minds of the minds, transport and safety, established by the standard.

8.4 The term for obtaining sodium chloride is not more than two rockets per day of preparation.

9 Orders for storing

9.1 The addition of sodium carbonate by the way of the previous day and regulation in technological instructions and recipes for specific food products.
