ASTM D1517-23: Standard Terminology Relating to Leather is a comprehensive reference document published by ASTM International. It provides standardized terminology for the leather industry, offering clear definitions of terms widely used in the manufacture, processing, specification, sampling, and testing of leather products. This standard aids manufacturers, suppliers, and users of leather and leather goods in ensuring consistent communication and understanding of industry-specific vocabulary.
ASTM D1517-23 is not a methods-based testing standard but a terminology reference designed to promote clarity and uniformity in the leather sector. Developed under the jurisdiction of ASTM Committee D31 on Leather, the terminology is useful for professionals across the leather supply chain, including those involved in procurement, quality control, sampling, and governmental specification processes.
General Leather Terms The standard outlines definitions for widely encountered leather terms, such as "full grain leather," "chrome tannage," "aniline finish," and "buffalo leather." These definitions clarify differences in leather types, finishes, and treatments.
Leather Processing and Tanning Methods ASTM D1517-23 details terminology related to various tanning methods (vegetable, chrome, oil, mineral), finishing processes (buffing, embossing, dyeing), and specialty leathers (chamois, nubuck, cordovan).
Sampling and Physical Testing Terms relevant for sampling and testing (e.g., "boil test," "float," "beam," "fatliquor") are included to support the evaluation of both physical and chemical properties. This ensures accuracy in communication regarding test specimens and procedures.
Types, Grades, and Uses The standard distinguishes between leather types by source animal (e.g., cowhide, pigskin, goatskin), by end-use (shoe leather, bag leather, garment leather), and by physical characteristics (boarded, embossed, bonded).
Common Leather Defects and Features Definitions for observable characteristics, defects, or surface conditions, such as "blocking," "blushing," "flanky," and "salt stain," help facilitate uniform assessment and quality grading.
ASTM D1517-23 is an essential tool in several practical contexts:
These related standards complement ASTM D1517-23 by offering methodologies for sampling and testing leather, ensuring comprehensive quality evaluation when paired with standardized terminology.
Using ASTM D1517-23 in conjunction with related standards facilitates clear, consistent, and professional communication within the global leather industry.
