Full title and description

ISO 5985:2002/Cor 1:2005 — Animal feeding stuffs — Determination of ash insoluble in hydrochloric acid — Technical Corrigendum 1. This corrigendum provides technical corrections and clarifications to the second edition of ISO 5985:2002 to ensure the test method text, figures and/or formulae are accurate and unambiguous.

Abstract

This document is a technical corrigendum to ISO 5985:2002. It updates and corrects elements of the original 2002 procedure for determining the fraction of ash that is insoluble in hydrochloric acid in animal feeding stuffs (two procedural variants are described in the main standard). The corrigendum is short (published as a 2‑page correction) and is intended to be read together with ISO 5985:2002 (edition 2).

General information

• Status: Published (technical corrigendum to ISO 5985:2002).
• Publication date: 9 March 2005 (Corrigendum 1 to the 2002 edition, published March 2005).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.120 — Animal feeding stuffs.
• Edition / version: Edition 2 (ISO 5985:2002) — Technical Corrigendum 1 (2005).
• Number of pages: 2 (corrigendum document).

Scope

This corrigendum amends ISO 5985:2002, which specifies two procedures for determining the ash fraction that is insoluble in hydrochloric acid for animal feeding stuffs. The original standard provides guidance on sample preparation, incineration (ashing), treatment of ash with hydrochloric acid, filtration and calculation of insoluble ash; the corrigendum corrects technical errors and clarifies wording so the method can be applied consistently by testing laboratories and feed manufacturers.

Key topics and requirements

• Two procedural variants (typically referred to as Procedure A and Procedure B) to accommodate different sample types and matrices.
• Requirements for sample preparation, drying and incineration to obtain ash suitable for the insoluble-in-HCl test.
• Treatment of the ash with hydrochloric acid, filtration or decantation steps, and washing to isolate the insoluble residue.
• Calculation of insoluble ash content (expressed as percentage of the original sample) and requirements for reporting results.
• Informative annex material (where present in the main standard) to assist interpretation and method application; the corrigendum addresses specific technical corrections only.

Typical use and users

Used by feed analysis laboratories, quality control teams within feed and ingredient manufacturers, regulatory authorities performing compliance testing, contract testing laboratories and researchers in animal nutrition. It is applied when quantifying mineral-related contaminants or non-soluble residues in feeds and when verifying compositional specifications that affect feed quality and safety.

Related standards

Main related documents include the base standard ISO 5985:2002 (the text amended by this corrigendum) and later technical amendments (for example ISO 5985/A1:2015). Related standards cover sample preparation and other feed analysis methods (for example ISO standards on sampling and preparative procedures such as ISO 6498 and other methods in the animal‑feeding‑stuffs series).

FAQ

Q: What is this standard?

A: It is a technical corrigendum (ISO 5985:2002/Cor 1:2005) that provides corrections and clarifications to the second edition of ISO 5985 (2002), which describes a method to determine the fraction of ash insoluble in hydrochloric acid in animal feeding stuffs.

Q: What does it cover?

A: It corrects and clarifies the procedural text, figures and/or formulae in ISO 5985:2002 so laboratories can apply the insoluble‑ash in HCl determination consistently; the substantive test method (two procedures, sample preparation, ashing, acid treatment and calculation) remains in the main standard.

Q: Who typically uses it?

A: Feed testing laboratories, quality control and product development teams at feed and ingredient manufacturers, regulatory testing bodies and academic researchers involved in feed composition and contaminant analysis.

Q: Is it current or superseded?

A: The corrigendum is a published correction to the 2002 edition. The main standard (ISO 5985:2002) remains the normative document; subsequent amendments (for example ISO 5985/A1:2015) have also been published, so users should check for the original standard plus this corrigendum and any later amendments to ensure they apply the latest consolidated requirements.

Q: Is it part of a series?

A: Yes — it belongs to the family of ISO methods for animal feeding stuffs and analytical procedures (ICS 65.120). It is related to other ISO methods covering sampling, sample preparation and the determination of various mineral and elemental constituents in feeds.

Q: What are the key keywords?

A: Ash insoluble; insoluble ash; hydrochloric acid; feed analysis; animal feeding stuffs; ISO 5985; corrigendum.
