This document specifies test methods applicable to prestressing steel (bar, wire or strand) for concrete. This document does not cover the sampling conditions that are dealt with in the product standards.

This document specifies the requirement for testing of special properties of hot-rolled steel sheet piles.

The method is applicable to chromium contents between 0.25 % (m/m) and 35 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international co-operative tests, and Annex B represents the precision data graphically.

This document specifies a method for the determination of Mn, P, Cr, Ni, Mo, Co, Cu, V, Ti, As and Sn in low alloy steel by inductively coupled plasma atomic emission spectrometry. The method is applicable to the determination of Mn, P, Cr, Ni, Mo, Co, Cu, V, Ti, As and Sn in content range (mass fraction) as follows: Mn:0.002%~2.0%; P:0.005%~0.1%; Cr:0.003~3.0%; Ni:0.005%~4.0%; Mo:0.003%~1.0%; Co:0.002%~0.2%; Cu:0.003~0.5%; V:0.002%~0.5%; Ti:0.002%~0.5%; As:0.003%~0.1%; Sn:0.003%~0.08%

Cancels and replaces the first edition (1978). Specifies a thiocyanate spectrophotometric method for the determination of the molybdenum content in steel and iron. Applicable to molybdenum contents between 0,005 % (m/m) and 0,125 % (m/m). Vanadium and tungsten interfere with the measurement if, because of their contents, the V/Mo ratio is greater than 16 or the W/Mo ratio is greater than 8.
