This International Standard specifies a method for the determination of the moisture and other volatile matter content of animal feeding stuffs. The method is applicable to animal feeding stuffs with the exception of: a) milk products; b) mineral substances; c) mixtures containing a considerable amount of milk products or mineral substances, for example milk replacers; d) animal feeding stuffs containing humectants (e.g. propylene glycol); e) the following simple animal feeding stuffs: animal and vegetable fats and oils (for which method A specified in ISO 662 [1] is applicable); oilseeds (for which a method is specified in ISO 665 [2]); oilseed residues (for which a method is specified in ISO 771 [3]); cereals, except maize, and cereal products (for which a method is specified in ISO 712 [4]); maize (for which the reference method specified in ISO 6540 [5] is applicable)
Abstract
Overview
ISO 6496:1999 specifies a standardized laboratory method for the determination of moisture and other volatile matter content in animal feeding stuffs by loss-on-drying. The method is based on measuring the mass loss of a test portion under defined drying conditions and is intended for routine quality control and official testing of most feed materials, with specific exclusions (see Scope).
Key topics and requirements
- Scope & exclusions: applicable to most animal feeding stuffs except milk products, mineral substances, mixes with significant milk/minerals (e.g., milk replacers), feeds containing humectants (e.g., propylene glycol) and certain single materials for which other ISO methods apply (fats & oils, oilseeds, oilseed residues, cereals, maize).
- Principle: loss of mass of a weighed test portion after drying; result expressed as a mass fraction (%) of substances lost on drying.
- Apparatus & materials:
- Analytical balance (readability 1 mg)
- Non‑corrodible or glass containers with tight lids
- Electrically heated oven: 103 °C ± 2 °C
- Vacuum oven: 80 °C ± 2 °C, capable of pressure
