Overview
ISO 2920:2004 Whey Cheese - Determination of Dry Matter (Reference Method) provides a standardized procedure for determining the dry matter content in whey cheese. Published jointly by the International Organization for Standardization (ISO) and the International Dairy Federation (IDF), this international standard ensures that the reference method for dry matter determination is consistent, reliable, and precise across laboratories and industries. The method is applicable to all types of whey cheese and is designed to yield accurate, repeatable results vital for quality control and regulatory compliance in the dairy sector.
Key Topics
- Reference Method: Establishes a validated procedure for measuring dry matter in whey cheese, including equipment specifications and detailed steps for sample preparation, drying, and weighing.
- Sample Handling: Emphasizes the importance of using representative, undamaged samples, with a suggested link to ISO 707 for guidance on sampling milk and milk products.
- Precision and Repeatability: Defines repeatability criteria, ensuring that results produced under the same conditions by the same operator will not differ by more than 0.2% of dry matter per 100 g of product.
- Reporting Requirements: Specifies what must be documented in the test report, including sample identification, method references, and any deviations from the standard procedure.
Applications
The ISO 2920:2004 standard is invaluable for a wide range of stakeholders in the dairy industry, including:
- Dairy Manufacturers: Ensures accurate determination of dry matter in whey cheese for quality assurance, process optimization, and product labeling.
- Regulatory Authorities: Provides a standardized, internationally recognized method for compliance checks, supporting food safety and labeling regulations.
- Quality Control Laboratories: Offers a robust reference procedure for routine analysis and proficiency testing.
- Technical Auditors and Inspectors: Facilitates benchmarking and validation of manufacturing and laboratory practices against international quality standards.
- Product Development and Research: Aids in the formulation of new whey cheese products by providing reliable analytical benchmarks.
By adhering to ISO 2920:2004, organizations can achieve consistent results, compare data across borders, and demonstrate adherence to best practices in whey cheese analysis.
Related Standards
To ensure comprehensive and harmonized analysis, users of ISO 2920:2004 may also reference the following relevant international standards:
ISO 707: Milk and Milk Products - Guidance on Sampling
Offers detailed procedures for obtaining representative samples, critical for reliable dry matter measurement.ISO 565: Test Sieves - Metal Wire Cloth, Perforated Metal Plate and Electroformed Sheet - Nominal Sizes of Openings
Sets out specifications for test sieves, which may be required for sample preparation under ISO 2920:2004.IDF 58:2004
Equivalent standard from the International Dairy Federation, published jointly with ISO, ensuring alignment within the dairy sector.
These linked standards support the effective and reliable application of ISO 2920:2004 for dry matter determination in whey cheese.
By following ISO 2920:2004, organizations demonstrate commitment to international best practices in dairy quality analysis. Incorporating this standard in routine operations strengthens food safety, enhances product consistency, and supports regulatory compliance within the global dairy industry.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has
been established has the right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
