ISO/TC 72/SC 8/WG 2 - Measurement and reduction of noise

This document covers the different types of weaving and knitting machines defined in ISO 5247 (all parts)[2] and ISO 7839[3], respectively. It is applicable to: full-width weaving machines with weft insertion by: shuttles; rigid, telescopic or flexible rapiers; projectiles; hydraulic (waterjet) or by pneumatic (airjet) nozzle; narrow fabric weaving machines with weft insertion by shuttles or needles; jacquard machines; knitting machinery including: circular knitting; flat bed knitting; warp knitting; raschel; cotton (flat weft weaving); other fabric manufacturing machines e.g.: multi-phase weaving machines; circular weaving machines; stitch bonding machines. NOTE Because of the high requirements on measurement conditions, grade 1 methods are normally not feasible for textile machinery.

ISO 23771:2015 provides technical information on the design of textile machinery with reduced noise emissions. Textile machines with a significant noise hazard are defined in ISO 11111 (all parts). ISO 23771:2015 supports the technical designer with the development of low-noise textile machinery. For this purpose, the significant sources of noise of the individual types of textile machines and suitable noise control measures are described.
