Standard and Norm
Standard and Norm
(OP)
What are the differences between the standards and norms?
To illustrate, a lab analysis is ISO 68 . . For this ISO standard, we have two different norms, namely; Turkish norm and French norm. These norms must be same or not?
If these norms are different from each other, how can we find the same result by using the different norms with a same standard?

As far as ISO 68 is concerned: it is a viscosity specification that says that a oil meeting ISO 68 must have a kinematic viscosity at 40 degrees Centigrade of 68 mm2/s +/- 10%. The ISO range is defined within a certain ISO standard and various national standards are derived from this standard and thus you may find the request for a ISO 68 oil based on a ISO, AFNOR, DIN etc standard - meaning exactly the same thing.
The purpose of the ISO standards is to get more or less globally accepted standards which make it far easier to import and export manufactured goods.
If you compare the Turkish and the French norm for ISO 68 you will notice that in the end they do describe the same thing.
If you look into national standards/norms you may notice that these are increasingly based on ISO standards.
