ISO 26845-2008 PDF

Full title and description

ISO 26845:2008 — Chemical analysis of refractories — General requirements for wet chemical analysis, atomic absorption spectrometry (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) methods. This International Standard defines apparatus, reagents, sampling and sample preparation, terms and definitions, basic procedures, loss on ignition determination and reporting requirements applicable to a number of ISO methods for refractory raw materials and products.

Abstract

ISO 26845:2008 specifies common, general requirements and procedures that support the chemical analysis of refractory products and raw materials when using wet chemical methods, atomic absorption spectrometry (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES). It is intended to be used together with a set of product- or material-specific method standards (see Related standards).

Scope

ISO 26845:2008 sets out the general requirements for apparatus, reagents, sampling and sample preparation, key terms and definitions, basic analytical procedures, determination of loss on ignition and the reporting of analytical results. The requirements apply where wet chemical analysis, AAS and ICP‑AES are used for the chemical characterisation of refractory raw materials and products; the standard is intended to be used in conjunction with product- and material-specific method standards (for example, those addressing magnesites, chromebearing refractories, zirconia-containing refractories and aluminosilicate refractories).

Key topics and requirements

• Definitions of apparatus and reagent quality and specification for laboratory equipment used in wet chemical, AAS and ICP-AES analyses.
• Sampling principles and sample preparation procedures to ensure representative and reproducible results.
• Standardised basic procedures for wet chemical determinations relevant to refractories.
• Requirements and procedure for determination of loss on ignition (LOI) for refractory samples.
• Guidance on reporting formats, expression of results and information to be included in analytical reports.
• Reference and applicability to a suite of product-specific ISO test-method parts (see Related standards).

Typical use and users

Typical users are analytical and quality-control laboratories in refractory manufacturing, materials testing institutes, research laboratories working on ceramic and refractory materials, and conformity/inspection bodies that verify composition and quality of refractory raw materials and products. The standard is used to harmonise laboratory practice, ensure comparability of results, and support compliance with product-specific test-method standards.

Related standards

ISO 26845:2008 is intended to be used together with a number of product- or material-specific method standards, notably the ISO series for chemical analysis of refractories such as ISO 10058 (parts 1–3), ISO 20565 (parts 1–3), ISO 21079 (parts 1–3) and ISO 21587 (parts 1–3). It is produced under the scope of ISO/TC 33 (Refractory products) and is often adopted as a regional/national standard (EN/UNE/ÖNORM/STN variants).

FAQ

Q: What is this standard?

A: ISO 26845:2008 is an International Standard giving general requirements for chemical analysis of refractory products and raw materials when using wet chemical methods, atomic absorption spectrometry (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES).

Q: What does it cover?

A: It covers apparatus and reagent specifications, sampling and sample-preparation procedures, key terms and definitions, basic analytical procedures, determination of loss on ignition (LOI) and the required content and format for reporting analytical results. It is intended to be used alongside product‑specific ISO test-method parts.

Q: Who typically uses it?

A: Laboratories and quality-control units in refractory manufacturing, independent testing laboratories, research organisations working with refractory ceramics and standards/conformity bodies.

Q: Is it current or superseded?

A: As published in March 2008 (Edition 1) the standard has been subject to ISO systematic review and is listed as published and confirmed in subsequent reviews; it remains the current edition as of the latest ISO bibliographic status. Users should check for any later amendments or a newer edition before purchase or formal reference.

Q: Is it part of a series?

A: Yes — ISO 26845 provides general requirements intended to be used together with a family of product- or material-specific ISO test standards (for example ISO 10058, ISO 20565, ISO 21079 and ISO 21587 series). It falls under the work of ISO/TC 33 (Refractory products).

Q: What are the key keywords?

A: Refractories; chemical analysis; AAS; ICP-AES; wet chemical methods; loss on ignition; sample preparation; analytical reporting.
