Full title and description

ISO 22284:2020 — Leather — Raw skins — Guidelines for preservation of goat and sheep skins. This International Standard gives guidance on preservation methods and handling to suppress microbiological activity and maintain the quality of raw goat and sheep skins during storage and transport.

Abstract

Provides concise, practical guidelines for preserving raw goat and sheep skins (curing, salting, brining, drying, chilling and related handling), including recommendations on salt characteristics, quantities and use of auxiliary substances to minimise spoilage and preserve leather-making quality.

General information

• Status: Published.
• Publication date: May 2020.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 59.140.20 (Leather — Raw hides and skins).
• Edition / version: Edition 1 (2020).
• Number of pages: 3 pages.

Scope

Applies to raw goat and sheep skins and provides guidance on preservation techniques to inhibit microbiological spoilage and preserve skin quality for subsequent leather processing. Topics include salt characteristics and quantities, recommended preservation methods (drying, wet salting, brining, dry salting, chilling), and advice on auxiliary chemicals and handling/storage conditions. The standard is intended as guidance rather than prescriptive test methods.

Key topics and requirements

• Characteristics and quality requirements for salt and auxiliary preservation substances (purity, particle size, acceptable additives and handling).
• Recommended salt quantities and application practices for wet salting, dry salting and brining to ensure effective preservation.
• Procedures and precautions for drying and chilling as alternative or complementary preservation methods.
• Handling, labelling and storage conditions to reduce contamination and mechanical damage during transport and storage.
• Practical guidance on minimizing microbiological activity and maintaining hide/skin condition for later leather processing.

Typical use and users

Primary users are slaughterhouses, skin collection centres, tanneries and leather processors, logistics and storage operators handling raw skins, and quality/procurement personnel who specify incoming raw-material preservation practices. The guidance helps reduce spoilage, improve processability and provide more consistent raw-material quality for leather manufacturers.

Related standards

Commonly used alongside other ISO and industry standards for leather testing and handling, for example ISO 17075 (chemical determination of Cr(VI) in leather), ISO 2419/2418 family standards on test specimen conditioning and sampling, and other ISO/TC 120 publications covering raw hides, tanned leather and leather products. These documents complement preservation guidance with sampling, conditioning and safety/testing requirements.

FAQ

Q: What is this standard?

A: ISO 22284:2020 is an ISO International Standard giving guidelines for the preservation of raw goat and sheep skins to prevent spoilage and retain quality for leather manufacture.

Q: What does it cover?

A: It covers preservation methods (drying, wet salting, brining, dry salting, chilling), salt and auxiliary-substance characteristics and quantities, and handling/storage recommendations for raw goat and sheep skins. It provides practical guidance rather than formal test methods.

Q: Who typically uses it?

A: Slaughterhouses, skin collection centres, tanneries and leather processors, logistics/storage operators, and quality/procurement teams specifying raw-skin preservation practices.

Q: Is it current or superseded?

A: ISO 22284 was published in May 2020 (Edition 1) and is listed as a published International Standard; like other ISO standards it is subject to periodic review (typically every five years). Users should check national or ISO catalogues for any revision or confirmation status updates.

Q: Is it part of a series?

A: It is one of several ISO documents related to leather and raw hides produced under ISO/TC 120; it is complementary to other standards that govern sampling, conditioning and chemical/physical testing of leather materials.

Q: What are the key keywords?

A: Goat skins, sheep skins, preservation, salting, brining, drying, chilling, raw skins, leather processing, ISO 22284.
