ÖNORM EN ISO 20565-2

Issue date: 2010 06 01

Chemical analysis of chrome-bearing refractory products and chrome-bearing raw materials (alternative to the X-ray fluorescence method) - Part 2: Wet chemical analysis (ISO 20565-2:2008)

This part of ISO 20565 specifies traditional (“wet process”) methods for the chemical analysis of chromebearing refractory products and raw materials. It is applicable to components within the ranges of determination given in Table 1. Table 1 — Range of determination (% by mass) Component Range SiO2 0,5 to 10 Al2O3 2 to 30 Fe2O3 0,5 to 25 TiO2 0,01 to 1 MnO 0,01 to 1 CaO 0,01 to 3 MgO 15 to 85 Na2O 0,01 to 1 K2O 0,01 to 1 Cr2O3 2 to 60 ZrO2 0,01 to 0,5 P2O5 0,01 to 5 LOI -0,5 to 5 NOTE These values are after the loss on ignition (LOI) has been taken into account.

Frequently Asked Questions about ÖNORM EN ISO 20565-2

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

Find out more about the benefits of multi-user licences

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
