Acoustics - Declared noise emission values of information technology and telecommunications equipment

ISO 9296:2017 is applicable to information technology and telecommunications equipment. It specifies: a) for a batch of equipment, the method for determining the following values: - the declared mean A-weighted sound power level, LWA,m; - the declared mean A-weighted emission sound pressure level, LpA,m; - the statistical adder for verification, Kv; - the statistical upper limit A-weighted sound power level, LWA,c; b) how acoustical and product information is to be published electronically or in hard-copy format in technical documents or other product literature supplied to users by the manufacturer or declarer; c) the method for verifying the noise emission values that are declared by the manufacturer or declarer.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
