SI standards are the Israeli national standards published by the Standards Institution of Israel (SII). They cover materials, construction, and product testing.
Why SI standards matter in testing
An SI standard defines the requirements and test procedure used for acceptance in Israel, including mechanical properties of construction materials verified by tensile testing.
What SI standards cover
SI includes construction and metal products — for example, reinforcing steel bars — with mechanical acceptance tested on universal testing machines, and many are aligned with ISO or EN.
How to read an SI designation
SI standards use the SI prefix and a number — for example, SI 739 for steel bars with improved bond for concrete reinforcement.
