ISO 10058-1-2008 PDF

Full title and description

ISO 10058-1:2008 — Chemical analysis of magnesite and dolomite refractory products (alternative to the X‑ray fluorescence method) — Part 1: Apparatus, reagents, dissolution and determination of gravimetric silica. This part specifies the apparatus, reagents, sample dissolution and the gravimetric method for determining silica in magnesite and dolomite refractory products and raw materials.

Abstract

Specifies procedures and required equipment for a wet chemical (gravimetric) determination of silica as an alternative method to X‑ray fluorescence (XRF) for magnesite and dolomite refractory materials. The standard defines reagents, dissolution steps and the gravimetric separation and weighing of silica for quality control and compositional analysis.

Scope

Defines the apparatus, reagents, dissolution procedure and the gravimetric method for the determination of silica content in magnesite and dolomite refractory products and raw materials, provided as an alternative to XRF analysis. It is intended for routine chemical analysis and quality control of refractories and raw materials where gravimetric determination of silica is appropriate.

Key topics and requirements

• Specification of laboratory apparatus and glassware required for sample decomposition and silica separation.
• Reagent purity and preparation instructions (acids, fluxes and washing solutions).
• Sample dissolution and decomposition procedures appropriate for magnesite and dolomite matrices.
• Gravimetric separation and precipitation methods for silica and final weighing procedure to calculate silica content.
• Precision, accuracy considerations and notes on suitability versus instrumental methods (XRF, FAAS, ICP‑AES described in companion parts).

Typical use and users

Used by analytical laboratories, refractory manufacturers, raw material suppliers and quality control personnel who require a standardized wet‑chemical gravimetric method for silica determination in magnesite and dolomite products. Also used in standards committees and testing laboratories as a reference alternative to instrumental XRF methods.

Related standards

ISO 10058 is published in multiple parts: ISO 10058-1:2008 (this part), ISO 10058-2:2008 (wet chemical analysis) and ISO 10058-3:2008 (instrumental methods: FAAS/ICP‑AES). The earlier consolidated standard ISO 10058:1992 was withdrawn and replaced by the 2008 multi‑part revision. National/adopted versions (EN, BS, UNE, EVS etc.) exist as adoptions of the ISO text.

FAQ

Q: What is this standard?

A: ISO 10058-1:2008 is the International Standard that specifies apparatus, reagents, dissolution and the gravimetric method for determining silica in magnesite and dolomite refractory products and raw materials.

Q: What does it cover?

A: It covers the required laboratory equipment and reagents, stepwise dissolution of samples, the precipitation/separation and gravimetric weighing procedures used to quantify silica as an alternative to XRF techniques.

Q: Who typically uses it?

A: Analytical chemists, QC laboratories in the refractory and mineral industries, suppliers of magnesite and dolomite, and standards/testing organizations.

Q: Is it current or superseded?

A: ISO 10058-1:2008 is the published Part 1 edition from 2008; the 2008 multi‑part revision replaced ISO 10058:1992. The ISO listing shows the 2008 part as published and confirmed on systematic review (the ISO record indicates review/confirmation activity). Users should check national standards bodies for any later national adoptions or amendments.

Q: Is it part of a series?

A: Yes — ISO 10058 was rewritten in 2008 as a series: Part 1 (gravimetric silica), Part 2 (wet chemical analysis) and Part 3 (instrumental techniques such as FAAS and ICP‑AES).

Q: What are the key keywords?

A: magnesite, dolomite, refractory, silica, gravimetric determination, wet chemical, apparatus, reagents, sample dissolution, XRF alternative.
