It is essential to ensure that the PDF version of the standard is obtained from a reputable source to guarantee its authenticity and accuracy.
The full document is typically 6 to 10 pages long. While public snippets and previews are available from various sources, the official PDF must be purchased or accessed through authorized distributors: INTERNATIONAL STANDARD ISO 14244
When oilseeds are processed to extract oil, the remaining meal is a high-protein ingredient used in animal feed. However, excessive heat during desolventizing and toasting can damage (denature) the protein. This reduces digestibility. Conversely, under-processing leaves anti-nutritional factors intact. The solubility test in KOH (potassium hydroxide) provides a rapid, reliable index of protein quality.
It defines which alloys or polymers are suitable for specific temperature ranges and chemical exposures.
A precise sequence of shaking, centrifuging, filtering, and digesting. Key parameters include:
PDI (measured by AOCS Ba 10-65) involves blending in water and is used mainly for soy flour. ISO 14244 uses a KOH solution and gentle shaking, making it more suitable for toasted soybean meal and other oilseed meals.
Following ISO 14244 is rarely just "optional." For many international projects, compliance is a contractual requirement. Failure to adhere to these guidelines can lead to:
Guidelines on how to label parts for traceability so that every component can be tracked back to its original factory melt. Why You Need the PDF Version
Statistical data on acceptable limits for differences between duplicate tests (repeatability) and between different laboratories (reproducibility).
Precise measurements are required to ensure that parts from different manufacturers can work together seamlessly (interchangeability).
: A test portion (typically 1.5 g) is dispersed in a KOH solution with a pH of approximately 12.5 (0.036 mol/L) and stirred for roughly 20 minutes.
