Full title and description

ISO 27085:2009 — Animal feeding stuffs — Determination of calcium, sodium, phosphorus, magnesium, potassium, iron, zinc, copper, manganese, cobalt, molybdenum, arsenic, lead and cadmium by ICP‑AES. This International Standard specifies an ICP‑AES (inductively coupled plasma atomic emission spectroscopic) method for multi‑element determination in animal feeds, feed materials and certain mineral premixtures.

Abstract

ISO 27085:2009 defines a closed‑method using ICP‑AES for quantifying major minerals (Ca, Na, P, Mg, K) and trace elements (Fe, Zn, Cu, Mn, Co, Mo) in animal feeding stuffs, and the elements As, Pb and Cd in minerals or premixtures used in feeds. The method’s detection/quantification capability depends on matrix and instrumentation; the published limit of quantification is about 3 mg/kg (or lower) and the procedure is not intended for very low concentrations.

Scope

Specifies an ICP‑AES analytical method for determination of major and trace elements in a range of animal feeding stuffs and for arsenic, lead and cadmium in minerals, premixtures and mixtures intended for feed use. The method gives guidance on sample handling and instrumental determination but notes matrix‑dependent detection limits and is not intended for ultra‑trace determinations.

Key topics and requirements

• Analytical principle: inductively coupled plasma atomic emission spectrometry (ICP‑AES) after appropriate sample preparation/digestion.
• Elements covered: Ca, Na, P, Mg, K, Fe, Zn, Cu, Mn, Co, Mo; and As, Pb, Cd for mineral/premixture matrices.
• Performance notes: method detection limits and quantification depend on matrix and instrument; published LOQ ≈ 3 mg/kg (matrix dependent).
• Intended application: routine laboratory testing of feeds, feed materials and mineral premixtures for quality control and regulatory/compliance testing where ICP‑AES is appropriate.
• Limitations: not suitable for measuring very low (ultra‑trace) concentrations without further validation or more sensitive techniques.

Typical use and users

Used by feed testing laboratories, regulatory agencies, quality control departments of feed and premixture manufacturers, research laboratories and accreditation bodies for verification of mineral and selected trace element contents in feeds and feed ingredients. National reference labs and organizations participating in ISO/TC 34/SC 10 work typically reference these methods when developing or harmonizing feed analysis protocols.

Related standards

European and national counterparts and updates cover similar ICP‑AES multi‑element methods for feeds (for example EN/ISO‑type methods published in CEN member states such as EN 15621:2017 and SN EN 15510 for ICP‑AES determination in feeds). Liaison organizations such as AOAC also publish complementary methods for feed analysis. These documents are commonly consulted when ISO 27085:2009 is withdrawn or superseded by harmonized regional standards.

FAQ

Q: What is this standard?

A: ISO 27085:2009 is an International Standard that specified an ICP‑AES method for determining a set of major minerals and trace elements in animal feeding stuffs and certain mineral premixtures. It was published by ISO in April 2009.

Q: What does it cover?

A: It covers sample scope, the ICP‑AES analytical approach and performance considerations for the listed elements (Ca, Na, P, Mg, K, Fe, Zn, Cu, Mn, Co, Mo and As, Pb, Cd in minerals/premixtures), and states practical limits on detection/quantification tied to matrix and instrumentation.

Q: Who typically uses it?

A: Feed testing laboratories, manufacturers’ QC labs, regulators and research laboratories working on feed composition and compliance testing. Experts and delegates involved with ISO/TC 34/SC 10 and national standards bodies also reference it in method development.

Q: Is it current or superseded?

A: ISO 27085:2009 has been withdrawn (withdrawal completed 1 April 2015). Users should consult current regional or international feed analysis standards (for example later EN/CEN or ISO documents) and national requirements for the currently accepted method.

Q: Is it part of a series?

A: It was developed under ISO/TC 34/SC 10 (Animal feeding stuffs) and is one of a number of ISO methods addressing sampling and analytical methods for feed. Related analytical standards and regional equivalents (EN/CEN, national standards, AOAC methods) form the practical family of test methods for feed analysis.

Q: What are the key keywords?

A: ICP‑AES, animal feeding stuffs, minerals, trace elements, feed analysis, LOQ, calcium, phosphorus, arsenic, lead, cadmium, ISO 27085:2009.
