Determining the mass of 1 meter Profile
1. Testing facilities and auxiliary devices: laboratory scales that provide weighing error of no more than 1 g, metal line according to GOST 427 or other measuring instrument that provides measurement accuracy of 1 mm.
2. The procedure for preparing and conducting the test:
the test shall be Carried out on three segments selected according to 6.5 of this standard. Measure the actual length and weight of the sample .
3. Processing results:
Weight 1 m profile m, g, calculated by the formula
where is the sample mass, g;
is the sample length equal to 1 m;
is the sample length, m.
the Result is rounded to 1 g.
