Elongation Tensile Load Standard

Elongation Tensile Load Standard


Alloy steel standard before breaking: 15: 20 % (International Standard)

Pakistani steel standard: 11%

This standard has been followed by Pakistan Central Testing Laboratory update as per ASTM standards 1952 not revised with the present needs.



What is the difference between Voltage and Ampere?

Voltage: Voltage is difference of potential to do work between two points.

Current: Current is flow of electrons due to applied voltage. Life safety is to use Low Voltage & high amperage current.


Heat ( Energy) = Power


Power = V x I = VI


100 KVA
