SXW Computer Control Steel Strand Testing Machine 300KN-500KN

SXW Computer Control Steel Strand Relaxation Testing Machine

Application:

It is mainly used in the tensile stress relaxation performance testing for pre-stressed steel wire, steel strand and pre-stressed steel bar.

Standard:

ASTM E328-2008 Standard Test Methods for Stress Relaxation Tests for Materials and Structures

ISO 15630-3:2002 steel for the reinforcement and prestressing of concrete-Test methods- Part 3: Prestressing steel, MOD

ISO 6934-4: 1991 Steel for the presressing of concrete – Part 4: strand, NEQ

GB/T 5224-2014 Steel strand for prestressed concrete

GB/T 10120-1996 Metallic materials -Tensile stress relaxation - Method of test

GB/T 21839-2008 steel for prestressed concrete -Test methods

Parameters:

Features:

1. It can show the relative diagram of residual testing power/relaxation rate with time, and relative diagram of temperature and time.

2. The stress relaxation properties of the specimen in 1000hours can be calculated by the machine.

3. It can gain the stress relaxation properties of specimen automatically and print a complete testing report.
