AS/NZS 4671:2019 Steel Reinforcing Tensile Testing machine
There are several global standards that specify mechanical properties and/or testing requirements for steel reinforcing bar (rebar). Some of the most common include ASTM A370, ISO 15630-1, BS 4449, AS/NZS 4671, JIS G 3112, GB 1499, and ACI 318. These standards include testing requirement that are specific to determining rebar tensile and bend properties. Many of these rebar standards also make reference to the widely recognized metals tensile testing standards, such as ASTM E8, ISO 6892-1, EN 10002-1, AS 1391, JIS Z 2241, GB/T 228.1 for general tensile testing guidance.
Typical results include Yield Point (ReH, Drop of Beam, Zero Slope), Proof Strength or Offset Yield Strength (Rp0.2, 0.2% Offset Yield), Tensile Strength (Rm), Elongation at Maximum Force (Ag, Agt) and Elongation after Fracture (A). The basic test and challenges are similar regardless of the specific standard being followed.

Description
AS NZS 4671 2019 Reinforcing Steel Rebar Tensile Testing machine
AS/NZS 4671:2019 Australian/New Zealand Standard Steel for the reinforcement of concrete
1. Introduction
This WAW serries Computerized Electro-hydraulic Servo Universal Testing Machine is widely used for tensile and bending test for steel rebar, carbon steel bar, deformed steel bar.
It adopts 4 columns with chrome plated and 2 leading screws, high stiffness, more stable.Press button operated hydraulic tensile grips, easy operate.
It’s computer controlled servo hydraulic type, the piston goes up and high precision load cell directly measuring testing force, encoder measuring displacement and electric extensometer measuring specimen’s extension. The machine is calibrated according to ISO 75001 and ASTM E4.
It can conform to testing standard such as SS 560, AS/NZS 4671, ISO 15630-1,2,3, ASTM A615/A615M ,BS EN 4449,BS EN 10025, ISO 6935-2, ASTM A706, NFA 35-016-1, JIS G3112 etc.
