ISO 2821:1974/Amd 1:1996

Overview

ISO 2821:1974/Amd 1:1996 is an important international standard focusing on the preservation of raw hides of bovine animals and horses through the method of stack salting. This amendment introduces minor technical updates to the original 1974 edition, particularly updating the terminology used-from "cattle" to "bovine animals"-to reflect a broader classification.

Developed by ISO Technical Committee TC 120/Subcommittee SC 1, which specializes in leather and raw hides, this standard ensures consistency and best practices in the preservation process. By adhering to ISO 2821 and its amendments, leather producers and processors can maintain raw hide quality during storage and transport, reducing spoilage and ensuring high-quality leather production.

Key Topics

• Scope of Preservation
  The standard covers the preservation of raw hides from bovine animals (including cattle) and horses, specifically through the stack salting technique.

• Terminology Update
  Amendment 1 replaces the term “cattle” with “bovine animals” throughout the standard to encompass a wider variety of species.

• Preservation Method
  Stack salting involves layering raw hides with salt in piles (stacks) to inhibit bacterial growth and decay during transportation and storage.

• Exclusions
  The original exclusion of buffalo hides was removed, reflecting adjustments in scope and terminology.

• Technical Amendments
  The amendment mainly consists of wording and terminology refinements without changing the fundamental preservation process or technical requirements.

Applications

ISO 2821:1974/Amd 1:1996 is highly relevant for industries and stakeholders involved in:

• Leather manufacturing
  Preserving raw hides effectively ensures premium leather quality and reduces material losses due to spoilage.

• Leather trading and export
  Standardized stack salting methods guarantee that hides remain preserved during long-distance shipping and handling.

• Tanning operations
  Proper preservation prior to tanning mitigates risks of microbial damage affecting hide integrity and leather final properties.

• Quality control and compliance
  Leather processing companies use the standard as a benchmark for quality assurance during raw material handling.

By implementing this internationally recognized preservation method, businesses can improve supply chain reliability and meet regulatory or customer expectations for raw hide quality.
