Steel and iron — Determination of total silicon content — Gravimetric method
The document specifies a gravimetric method for the determination of the total silicon content in steel and iron. The method is apllicable to silicon contents between 0,10 % (m/m) and 5,0 % (m/m). For samples containing molybdenum, niobium, tantalum, titanium, tungsten, zirconium or high levels of chromium, the result are less precise than for unalloyed steels.
Steel and iron — Determination of sulfur content — Methylene blue spectrophotometric method
The method specified is applicable to sulfur contents between 0,0003 % (m/m) and 0,010 % (m/m). However, niobium, silicon, tantalum and titanium interfere in the determination of sulfur, and application range and test portion masses of the method depend on the concentration of the interfering elements.
Safety data sheet for chemical products — Part 1: Content and order of sections
Presents information for the compilation and completion of a safety data sheet. Defines specifically the general layout of the SDS, the 16 standard headings, the numbering and the sequence of these 16 standard headings, the items necessary to fill in an SDS and the conditions of their applicability or utilization.
Describes the contents of calibration tapes for various broadcast VTRs, allowing adjustment of the machine so that it will give optimum reproduction of a first-generation verified recording.
