BIS CERTIFICATION FOR SYNTHETIC MICRO FIBRES
IS 16481:2022

IS 16481:2022 covers Synthetic Micro-Fibres. The Bureau of Indian Standards adopted this Indian standard after the textile division council approved the draft finalized by the technical textiles for Build tech sectional committee.

This standard specifies the physical, application, and functional requirements for synthetic microfibers such as polyester, nylon, and polypropylene fibres, etc. for use in cement-based matrices for secondary reinforcement in construction works such as concrete roads and pavements, industrial and commercial floorings, residential and commercial buildings, bridges and elevated structures, water retaining structures and dams, ports and under sea concrete structures, plaster, shortcrete, etc.

This standard primarily addresses the requirements for synthetic fibres used for secondary reinforcement of concrete, such as polyester, polypropylene, and nylon. The synthetic fibres used for secondary reinforcement in concrete must meet the requirements specified in clause 4 of this standard, as well as the physical, application, and functional requirements specified in the standard.

Only virgin synthetic fibres with cut lengths ranging from 6mm to 25mm that are inert to the concrete environment may be used as secondary reinforcement in cement-based matrices; no recycled material is permitted. Fibers must be well dispersed in a cement-based matrix to achieve uniform functional properties.

TESTS

The following test shall be carried out in accordance with the method prescribed.

1. Isophthalic acid content
2. Resistance of fibres
3. Water absorptive capacity
4. Specific gravity
5. Melting and glass transition temperature
6. Viscosity

Packing and Marking:

Packing and marking shall be done in accordance with IS 16481:2022. The bag or paper pouches shall be marked with information as specified in the standard.

Conforming to the requirements of this standard, the product(s) may be certified under the provisions of the Bureau of Indian Standards Act, 2016 and the Rules and Regulations framed thereunder, and the products may be marked with the Standard Mark (ISI Mark). The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The BIS grants a license based on a successful assessment of manufacturing infrastructure, quality control, testing capabilities, and production process.
