ISO 7482-2:1999

Overview

ISO 7482-2:1999 establishes international guidelines for the grading of raw goat skins based on their mass and size. Published by the International Organization for Standardization (ISO), this standard applies to both fresh and cured skins, including those preserved by sun-drying, dry-salting, or wet-salting. The document serves as part of the broader ISO 7482 series, which addresses standardization in the classification of raw goat skins for the leather industry.

Clear, consistent grading is vital for fair trade, quality assessment, and optimal utilization of goat skins globally. By standardizing measurement and categorization methods, ISO 7482-2:1999 supports seamless commerce and high-quality end products in the leather sector.

Key Topics

• Definitions and Terminology
  The standard provides clear definitions for key terms such as butt, cured skin, dry-salted skin, fresh/green skin, shanks, sun-dried skin, and wet-salted skin, ensuring a common language across the industry.

• Presentation Criteria
  Goat skins must be presented in prescribed forms, including specific cut points for the head, shanks, and tail, and must be free from excess fat or flesh. This facilitates uniformity and ease of grading.

• Measurement Methods
  ISO 7482-2 details procedures for measuring length and width:

  • Length is measured along the backbone from the tail root to the front throat.
  • Width is taken at the widest part of the belly.
  • The area is calculated as length multiplied by width.

• Mass Determination
  The standard outlines how to prepare skins (removal of excess water or salt) and specifies weighing procedures for fresh, wet-salted, dry-salted, and sundried skins.

• Grading Categories
  Skins are classified based on either size (length or area) or on mass. Grading tables define categories such as extra-small, kid, small, medium, large, and extra-large for both dimensional and weight-based grading.

Applications

ISO 7482-2:1999 is crucial across various points of the goat skin value chain:

• Processing Facilities and Tanneries
  Ensures incoming raw goat skins are graded consistently, improving batch uniformity and process efficiency.

• Quality Control and Inspection
  Standard grading empowers objective inspection and guarantees that only compliant skins are advanced for further processing or sale.

• Trade and Export/Import
  International merchants and customs authorities rely on standardized grading to facilitate fair pricing and transparent trading practices.

• Leather Goods Manufacturing
  Provides manufacturers with clear expectations regarding the quality and suitability of raw materials, supporting premium product development and traceability.
