Full title and description

Animal feeding stuffs — Determination of ash insoluble in hydrochloric acid — Amendment 1 (ISO 5985:2002/Amd 1:2015). This document is Amendment 1 to ISO 5985:2002 and updates/clarifies aspects of the test methods used to determine the fraction of ash that is insoluble in hydrochloric acid for animal feeding stuffs.

Abstract

This amendment provides limited, targeted changes to ISO 5985:2002 (the second edition), intended to correct or clarify procedural and editorial points in the method for determining ash insoluble in hydrochloric acid. The amendment is concise (published as a short amendment document) and applies directly to the procedures described in the 2002 standard.

General information

• Status: Published.
• Publication date: November 2015 (Amendment 1 to ISO 5985:2002).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.120 (Animal feeding stuffs).
• Edition / version: Amendment 1 to Edition 2 (ISO 5985:2002, amended 2015).
• Number of pages: 2 (amendment document).

Scope

The amendment applies to ISO 5985:2002 and its two procedures for determining ash insoluble in hydrochloric acid in animal feeding stuffs. ISO 5985 specifies Procedure A (for simple organic and most compound feeds) and Procedure B (for minerals, mineral mixtures and feeds whose HCl‑insoluble ash exceeds 1 % by mass as determined by Procedure A); the amendment updates or clarifies elements of those methods as published in November 2015.

Key topics and requirements

• Clarification/correction of procedural steps in the determination of ash insoluble in hydrochloric acid (applies to the methods given in ISO 5985:2002).
• Procedures A and B for sample preparation, acid digestion with hydrochloric acid, filtration, drying/ignition and weighing of the insoluble residue.
• Guidance on applicability of Procedure A vs Procedure B (Procedure B for ash insoluble > 1 % mass fraction).
• Editorial and technical amendments designed to improve repeatability and clarity of test reporting.

Typical use and users

This amendment and the base ISO 5985 method are used by feed testing laboratories, quality control units in feed manufacture, regulatory laboratories, and research institutions involved in animal nutrition and feed safety. It supports routine quality control, contamination detection (e.g., soil, sand, siliceous material), and regulatory compliance testing.

Related standards

Related feed analysis standards include ISO 5984 (Determination of crude ash), ISO 6496 (Determination of moisture and other volatile matter in animal feeding stuffs) and other ISO/TC 34/SC 10 publications covering feed analysis and methods. The amendment specifically amends ISO 5985:2002 and should be used together with that base document.

A: ISO 5985:2002/Amd 1:2015 is Amendment 1 to ISO 5985:2002, titled "Animal feeding stuffs — Determination of ash insoluble in hydrochloric acid." It is a short amendment document published in November 2015 by ISO.

Q: What does it cover?

A: It updates or clarifies parts of the test method in ISO 5985:2002 for determining the proportion of ash insoluble in hydrochloric acid in animal feeding stuffs. The base standard defines two procedures (A and B) covering different feed types and ash levels.

Q: Who typically uses it?

A: Laboratories performing feed analysis, feed manufacturers' QC teams, regulatory laboratories and researchers in animal nutrition and feed safety use the method and its amendment for accurate, standardized determination of HCl‑insoluble ash.

Q: Is it current or superseded?

A: The document is an amendment published in 2015 to ISO 5985:2002. It remains the published amendment to that edition; users should check with their national standards body or ISO for any later revisions or superseding editions.

Q: Is it part of a series?

A: ISO 5985 and its amendment form part of the family of ISO methods for feed analysis maintained by ISO/TC 34/SC 10; other related ISO standards address crude ash, moisture and other compositional determinations for animal feeding stuffs.

Q: What are the key keywords?

A: Key keywords include "animal feeding stuffs", "ash insoluble", "hydrochloric acid", "feed analysis", "Procedure A", "Procedure B", and "ISO 5985:2002/Amd 1:2015".
