Mandatory specifications for Polyester Industrial Yarn (IDY) - IS 17264:2019 as per Bureau of Indian Standards
The IS 17264:2019 sets mandatory requirements for Polyester Industrial Yarn (IDY) entering India. This standard, published by the Bureau of Indian Standards (BIS), ensures consistent quality and performance for various industrial applications.
IS 17264:2019 ensures quality for industrial yarn imports into India. A vital Indian standard published by the Bureau of Indian Standards (BIS) in 2019, it sets mandatory requirements for all imported IDY imported by India. This standard plays a crucial role in guaranteeing quality and performance of IDY used in various industrial applications.
These standards are mandatory for all imported IDY since April 5, 2022. Non-compliance can lead to product detention and re-exportation. Overall, IS 17264:2019 plays a crucial role in maintaining quality standards for IDY imports and contributes to the efficient functioning of various Indian industries.
Key features
- Wide range of deniers:Covers IDY yarns ranging from 75 to 3300 deniers, catering to diverse industrial needs like tire cords, geotextiles, and webbing.
- Physical and chemical properties:Specifies minimum and maximum acceptable levels for properties like moisture regain, ash content, melting point, breaking strength, and elongation, ensuring consistent performance.
- Tenacity classification:Categorizes IDY based on its tenacity (high or low), allowing selection for specific applications requiring strength or flexibility.
- Optional oil content:Provides flexibility for applications requiring specific oil finishes, determined by buyer-seller agreement.
- Tolerances and additional tests:Defines acceptable variances for key properties and outlines additional tests for special needs like high modulus or flame retardant.
