Описание (английский):

The method is applicable to products having contents greater than 1 g/kg. It consists in ashing of a test portion, treatment of the ash with hydrochloric acid and precipitation of the calcium as calcium oxalate, dissolution of the precipitation in sulfuric acid and titration with standard volumetric potassium permanganate solution of the oxalic acid formed.

Overview

SIST ISO 6490-1:1995 is an international standard published by the International Organization for Standardization (ISO) that specifies a titrimetric method for the determination of calcium content in animal feeding stuffs. This part of ISO 6490 is designed for products with calcium levels greater than 1 g/kg. The procedure involves ashing the sample, treating the ash with hydrochloric acid, precipitating calcium as calcium oxalate, dissolving the precipitate in sulfuric acid, and performing a titration with a standard volumetric potassium permanganate solution.

This standard is essential for laboratories and quality control professionals working in the animal feed industry, ensuring consistency and reliability in calcium analysis across a wide range of feeding products.

Key Topics

Applicability: The method is suitable for all animal feeding stuffs with more than 1 g/kg of calcium content.

Sample Preparation: Samples are first ashed in a muffle furnace to destroy organic matter before analysis.

Chemical Reagents Used:

Hydrochloric acid for treating ash
Sulfuric acid for dissolving precipitates
Potassium permanganate for titration

Volumetric Analysis: Calcium is quantified via titration, a key volumetric analysis technique used in feed laboratories.

Repeatability: The method specifies tight repeatability requirements, enhancing its reliability for routine quality assurance.

Reporting: The method includes detailed guidelines for reporting and calculation, ensuring standardized documentation and compliance.

Applications

SIST ISO 6490-1:1995 is widely used in the animal feed industry for:

Quality Assurance: Ensuring proper calcium levels in formulated feed products is vital for animal health, particularly for livestock and poultry.

Feed Formulation: Accurate calcium content determination helps manufacturers meet nutritional requirements and regulatory standards.

Regulatory Compliance: Laboratories and feed producers use this standardized method to comply with national and international nutritional labeling regulations.

Comparison Testing: The standardized protocol enables reliable comparison between different batches and suppliers.

Research and Development: Used by researchers developing new feed mixtures or studying the bioavailability of calcium in various formulations.

Related Standards

ISO 6490-2: Animal feeding stuffs - Determination of calcium content - Part 2: Atomic absorption spectrometric method. Recommended for samples with very low calcium content.

ISO 6497: Animal feeding stuffs - Sampling. Specifies standard procedures for obtaining representative samples.

ISO 6498: Animal feeding stuffs - Preparation of test samples. Provides guidance on preparing samples for analysis.

Practical Value

Implementing SIST ISO 6490-1:1995 offers significant benefits:

Consistency: Ensures uniformity in testing methods and results across laboratories and geographic regions.

Accuracy: Provides a highly reliable method for determining calcium content, minimizing nutritional variability in feed.

Compliance: Meets regulatory and customer requirements for traceability and transparency in feed production.

Quality Control: Enhances feed safety and animal nutrition management through precise mineral analysis.

International Recognition: As an ISO standard, it enables seamless communication of results in global trade and regulatory affairs.
