|ICS Code (Noise emitted by machines and equipment):||17.140.20|
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 nonwoven machinery. It defines a noise test code for
- cross lappers,
- lap drafters,
- pre-needle machines,
- needle punchers,
- stitch bonding machines (nonwovens),
- water jet bonding machines, and
- praying machines.
The other machines of nonwoven lines are covered in ISO 9902-2, ISO 9902-6 and ISO 9902-7.
This part of ISO 9902 is applicable to engineering (grade 2) and survey (grade 3) test methods, in accordance with the International Standards to which it makes normative reference.
NOTE Because of the high requirements on measurement conditions, grade 1 methods are normally not feasible for textile machinery.
