Overview
ISO 10122:2014 - Reinforcement materials - Tubular braided sleeves - Basis for a specification - provides a standardized basis for preparing specifications for tubular braided sleeves used as reinforcements in plastics. It covers sleeves braided from all types of yarn or roving and sets out the description, characteristic features, sampling/conditioning, test methods, packaging, ordering information and storage requirements needed to produce consistent product specifications and catalog entries.
Key topics and technical requirements
- Scope and purpose: Establishes the elements a specification should contain when describing tubular braided sleeves for composite/plastic reinforcement (not a prescriptive manufacturing standard).
- Description & designation (Clause 4): Defines the full technical description (yarn designation, construction, braid angle at a specified diameter, treatment, mass per metre) and a practical three-group designation code (material code, diameter at 45° braid angle, mass per metre at 45°). Example material code letters: G (Glass), C (Carbon), A (Aramid), E (Ceramic), P (Polyethylene). Example: “CG 024 012”.
- Characteristics to specify (Clause 5):
- Construction details: yarn types, linear density (tex), number of carriers, braid type (standard or paired), braid angle, mass per metre and nominal thickness.
- Surface treatments: textile size, plastic size, desized, coupling finishes, with amount of size/finish expressed per ISO 1887 / ISO 10548.
- Defect categories and requirement that specifications define acceptable defect levels (ends out, tight ends, folds, dirt, grease, faulty splices, angle deviation).
- Sampling and conditioning (Clause 6): Sampling from delivery units (rolls/spools) and specimen conditioning per ISO 291 (typical atmosphere: 23 °C ±2 °C, 50 ±10 % RH).
- Test methods (Clause 7):
- Thickness measurement (ISO 4603 for flattened braid).
- Procedures to determine diameter, braid angle, and mass per metre length, including the use of a mandrel/tube for characterization and the calculations used to normalize values to a 45° fibre angle.
- Packaging, ordering and storage (Clauses 8–9): Requirements to prevent property deterioration during transport/storage and required ordering data (designation code, braid angle, yarn type, roll mass, etc.).
Practical applications and who uses it
- Useful for manufacturers, suppliers and purchasers of reinforcement materials for composite parts and plastic components.
- Applied by: specification writers, quality engineers, product managers, procurement teams, and testing laboratories involved in composite reinforcement supply chains.
- Typical industries: automotive, aerospace, marine, wind energy, sporting goods and industrial composites where tubular braided sleeves are used for structural reinforcement, cable protection or as preforms.
