Chemical analysis of refractories containing alumina, zirconia, and silica. Refractories containing 5 percent to 45 percent of ZrO2 (alternative to the X-ray fluorescence method) - Wet chemical analysis1 Scope This part of ISO 21079 specifies methods for the chemical analysis of AZS (alumina, zirconia, and silica) refractory products (containing 5 % to 45 % of ZrO2) and raw materials, using traditional (wet) methods. This part of ISO 21079 is not applicable to MgO based refractories. This part of ISO 21079 gives alternatives to the X ray fluorescence (XRF) method given in ISO 12677.

such as building sites and earth moving sites

Limits for such cases are given

Pedestal drilling machines

Many electronic transactions within ICT systems have security requirements which depend on an understood or specified level of confidence in the identities of the entities involved

Index of defined terms used in this particular standard

BS EN 12697-3 is the third part of the series that describes a test method for the recovery of soluble bitumen from bituminous mixtures used in road

This should minimize confusion across languages or caused by the use of local terms

rainscreen overcladding systems and external wall insulation systems when fixed to and supported by a masonry substrate and exposed to an external fire under controlled conditions
