DETERMINATION OF THE MASS OF 1 METER OF THE PROFILE

1. Test facilities and auxiliary devices: laboratory scales that provide a weighing error of no more than 1 g., a metal ruler according to GOST 427 or another measuring instrument that provides measurement accuracy of 1 mm.

2. Procedure for preparing and conducting the test:

The test is carried out on three segments selected according to 6.5 of this standard. The actual length and mass of the sample are measured .

3. Processing the results:

The mass of 1 m of the profile M, g, is calculated by the formula

where is the mass of the sample, g;

— sample length equal to 1 m;

— sample length, m.

The result is rounded to 1 g .
