Описание (английский):

This document specifies the position of laboratory test specimens within a piece of leather and the method of labelling and marking the laboratory test specimens for future identification. In addition, this document specifies the design of press knives for cutting test pieces and the preparation of test pieces. It is applicable to all types of leather derived from mammals, irrespective of the tanning used. It is not applicable to leathers derived from birds, fish, reptiles or furs.

Overview

ISO 2418:2023 - Leather - Chemical, physical, mechanical and fastness tests - Position and preparation of specimens for testing provides clear, standardized rules for selecting, labelling and preparing laboratory specimens from leather. The fourth edition defines how to locate specimen areas on whole hides, sides and typical segments (bends/butts, shoulders and bellies), how to mark and store specimens, and basic requirements for cutting tools (press knives) and test-piece preparation. It applies to leathers derived from mammals and is not applicable to bird, fish, reptile or fur leathers.

Key topics and requirements

Specimen position and segmentation

Defines segmentation (bend/butt, shoulder, belly) and prescribes exact specimen areas with accompanying figures for whole hides and segments.
Includes tolerances for location (e.g., AE distance table: AD < 350 mm → AE = 0 mm; 350 ≤ AD < 600 mm → AE = 20 mm; AD ≥ 600 mm → AE = 50 mm).

Selection criteria

Test specimen areas must be free of obvious defects (scratches, flay cuts).
Preference given to specimens cut from whole hides or sides to reduce variability between segments.

Test-specific location guidance

Distinct guidance for physical and mechanical, chemical, and colour fastness testing (different shaded/non-shaded areas in the standard’s figures).
Rules for when to extend sampling area (e.g., when minimum mass for chemical testing is not met).

Storage and contamination control

Store specimens to avoid contamination and localized heating.

Identification and marking

Mark backbone direction with an arrow; label specimens with batch reference, preparation date, specimen reference and segment (bend/shoulder/belly).

Press knives and preparation

Specifies design requirements for press knives and procedures for cutting and preparing test pieces (see Clauses 7 and 8).

Practical applications

Ensures consistent, repeatable specimen preparation for laboratory testing across tanneries and testing facilities.

Supports quality control (physical, chemical, mechanical and colour fastness testing) and reduces inter-laboratory variability.

Provides clear rules for arbitration testing - only specimens from specified whole-hide areas are acceptable unless otherwise agreed.

Useful for creating documented traceability of specimens for regulatory compliance and product certification.
