6.2 the Weight of the batch of flux should not exceed 80 t in the smelting furnaces with a capacity of over 5 tons In furnaces of small capacity, i.e. up to 5 tonnes, the weight of the batch of flux should not exceed 20 tons

6.3 Sampling for quality control of flux is carried out after sifting and drying flux before filling of the bunker.

6.3.1 To control the quality of the flux from each party select a sample weighing at least 10 kg, made of spot samples. Selection of point samples are performed by the manufacturer of the flux in the packaging process of the products. The mass of each point of the sample should be of 0.05−0.3 kg.

When packing the flux in bags take one spot sample from every tenth bag.

When packing containers be taken away not less than four spot samples from each container, and should take samples, when filling the flux crossing all the flow.

When applying the flux to the hopper taken at least four spot samples from a moving vehicle for hours.

6.3.2 Selected sample is thoroughly mixed, after which the method of kvantovaniya select a sample weighing not less than 2.5 kg. From the samples separated by one charge weighing 500 g to determine the chemical composition of the flux, the remaining flux Quartet, getting four portions, each weighing not less than 0.5 kg, of which two portions are selected for the two parallel measurements of bulk density, the third portion is divided in half, getting two servings of 250 g to determine particle size distribution, and from the last portion after kvantovaniya selected two sample (100±5) g to control uniformity.

6.4 If unsatisfactory test one of the indicators for this indicator, repeat the test at twice the sample taken from the same batch of flux.

The results of repeated tests are final.

6.5 By agreement between manufacturer and consumer with the necessary evidence of quality party welding fused flux conducting inspection of welding-technological properties.

7 test Methods

7.1 Chemical composition of the flux is determined according to GOST 22974.1-GOST 22974.14. Allowed the use of other methods of analysis if their metrological characteristics are not inferior to the characteristics of the techniques included in the above standards. In the case of disagreement in determination of chemical composition of flux the test is performed the churchyard 22974.1-GOST 22974.14.

7.2 Bulk density flux is determined by filling a measuring glass cylinder with a capacity of 500 cmaccording to GOST 1770 or other normative document. The filling of the cylinder the flux is carried out without sealing the container with a spout with a height of not more than 20 mm above the upper edge of the cylinder. The flux is weighed with an error of no more than 1 year

Bulk density flux , g/cm, is calculated by the formula

, (1)

where is the mass flux, filled the cylinder, g;

 — the volume of a cylinder, cm.

7.3 grain Size and granulometric composition of the flux is determined by the simultaneous screening of a sample of three sieves with openings of appropriate size for (60±5) C and subsequent weighing of the balance on the large sieve and sifting for small screens with the error not more than 0.1%. The relative amount of grains , %, is calculated by the formula

, (2)

where is the mass balance on a large sieve or sifting a small sieve, g;

is the total mass of sample, g.

To determine the granulometric composition of the flux should be applied to sieves with meshes N 025, N-035, N Of 1.6, N 2,8, 4,0 N according to GOST 3826 or GOST 6613.

7.4 To determine the moisture flux hitch weight (100±5) g were placed in pre-dried metal Cup and allowed to stand at a temperature of (300±10) °C in a drying Cabinet for (60±5) min. After cooling in a desiccator for (40±5) min the sample is weighed. The humidity flux , %, is calculated by the formula

, (3)

where is the initial mass of sample, g;

 — final mass of sample, g.

The final result of the analysis taking the arithmetic mean of the results of two parallel measurements, the difference between them should not exceed the humidity:

— from 0,02 to 0,04−0,005%;

— from 0.04 to 0.08−0,007%;

— from 0.08 to 0.20 to 0.10%.

7.5 Uniformity of structure and color of the flux is controlled by visual inspection of the sample weight (100±5) g where the increase is not less than 2.5 times. Particles of another color, as well as foreign particles are taken and weighed. Weighing results are expressed in percent by weight of the hitch.
