ISO DIS 9902-6

Description / Abstract: This part of ISO 9902, taken together with ISO 9902-1, specifies the mounting, operating and measuring conditions required for the measurement, declaration and verification of noise emitted by fabric manufacturing machinery. It is applicable to engineering (grade 2) and survey (grade 3) methods, in accordance with the International Standards to which it makes normative reference.

This part of ISO 9902 covers the different types of weaving and knitting machines defined in ISO 5247 and ISO 7839, respectively. It is applicable to full-width weaving machines with shuttles, with rigid, telescopic or flexible rapiers, with projectiles, and to those with weft insertion by hydraulic (waterjet) or by pneumatic (airjet) nozzle. It is also applicable to narrow fabric weaving machines with weft insertion by shuttles or needles, to other weaving machines of the multi-phase and circular weaving types, and to Jacquard machines. This part of ISO 9902 is applicable to knitting machinery including circular knitting, flat bed knitting, warp knitting, Raschel, cotton (flat weft weaving) and stitch bonding machines.

NOTE Because of the high requirements on measurement conditions, grade 1 methods are normally not feasible for textile machinery.
