ISO 9902-3:2001 繊維機械 — 騒音試験コード — Part 3: 不織布機械 | ページ 2

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this part of ISO 9902 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 9902-3 was prepared by Technical Committee ISO/TC 72, Textile machinery and machinery for dry-cleaning and industrial laundering, Subcommittee SC 8, Safety requirements for textile machinery.

This first edition of ISO 9902-3, together with ISO 9902-1, ISO 9902-2, ISO 9902-4, ISO 9902-5, ISO 9902-6 and ISO 9902-7, cancels and replaces ISO 9902:1993, which has been technically revised.

ISO 9902 consists of the following parts, under the general title Textile machinery — Noise test code:

• Part 1: Common requirements
• Part 2: Spinning preparatory and spinning machinery
• Part 3: Nonwoven machinery
• Part 4: Yarn processing, cordage and rope manufacturing machinery
• Part 5: Weaving and knitting preparatory machinery
• Part 6: Fabric manufacturing machinery
• Part 7: Dyeing and finishing machinery

Introduction

Nonwoven lines of textile machinery include machines for:

• preparation (bale breaker, automated blending bale opener, carding willow, blender, fan, condenser, opener),
• feeding (hopper feeder, flock feeder),
• web formation (card, cross lapper), and
• bonding (lap drafter, pre-needle machine, needle puncher, stitch bonding machine for nonwovens, spray bonding machine, water jet bonding machine, calender, dryer, coating machine).

1 Scope

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.
