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.
