Testing

5mm bar and couplers were extensively tested by Holmes Solutions back in 2014. 12mm to 40mm bars tested by Opus NZ to ISO15835 slip test, tensile test and low cycle loading test.

a) Test Methods to ISO 15835-2:2009(E), ISO 15630-1:2010, BS EN ISO 6892-1:2009 & AS/NZS 4671:2001

b) To meet the ISO 15835-1:2009(E) Strength and ductility under static forces (clause 5.2) and Slip under static forces (clause 5.3)

c) To meet the ISO 15835-1:2009(E) Properties under low cycle reverse elastic-plastic loading (clause 5.5) for Couplers of category S2 (clause 5.5.2) Mode of failure was bar break outside the splice zone.
