As the choice of threads in many respects depends on conditions and a scope, the producer before production of products should carry out a number of tests of properties of threads to check how chosen threads are suitable for this area of a prmeneniye. The technical characteristics stated above are based on the current average values and can be considered only in common goals as approximate estimates. |
