Engine noise from vehicles

Groups: 
  • Light Commercial Van
Category: 
  • Engine noise
  • Environment
  • Transportation

Basic

Requirements and Criteria Type: 
  • Award Criteria

Main Objective: 

The main purpose of the environmental criterion is to reduce engine noise from vehicles in built-up areas with low speed limits and thus contribute to a better residential environment.

Requirement Specification: 

Tendered commercial vehicles with a noise level of lower than 72 dB(A) will be awarded points on a scale of 0-10 where 10 points is the best.

Documentation of the Requirement Specification: 

The main purpose of the environmental criterion is to reduce engine noise from vehicles in built-up areas with low speed limits and thus contribute to a better residential environment.

Information about the Requirement Specification: 

I 2017 var 98% av førstegangsregistrerte varebiler over 1900 kg. Derfor vurderes alle N1-klasser under ett. Dette betyr imidlertid at for de tyngste varebilene vil basiskravet være mest relevant, mens avansert er mer relevant for lettere varebiler.

By 2017, 98% of first-time registered vans weighed more than 1900 kg. Therefore, all N1 classes are considered as a whole. This means, however, that for the heaviest vans, the basic level will be most relevant, while advanced is more relevant to lighter vans.

Annex 1 of the Vehicle Regulation stipulates maximum permitted levels for noise depending on the vehicle's power to weight ratio. The statutory requirement is based on Regulation EU 540/2014 on the sound level of motor vehicles and of replacement silencing systems, Annex III.

The criterion's weighting must be assessed in relation to the organisation's overarching climate and environmental objectives. It is important that the buyer sets requirements of 72 dB(A).

Difi's power output meter can be used to show the climate and environmental effects of the selected requirement and criterion in a given reference scenario.

Requirements and criteria must be followed up. Guidance can be found on Difi's website, "Kontraktsoppfølging" (In Norwegian)

 

 

 

Advanced

Requirements and Criteria Type: 
  • Award Criteria

Main Objective: 

The main purpose of the environmental criterion is to reduce engine noise from vehicles in built-up areas with low speed limits and thus contribute to a better residential environment.

Requirement Specification: 

Tendered commercial vehicles with a noise level of lower than 74 dB(A) will be awarded points on a scale of 0-10 where 10 points is the best.

 

Documentation of the Requirement Specification: 

The tenderer can document the noise level per vehicle model as specified in EU type-approval. The information that must be stated can be found under "Test results" and "Sound level of moving vehicle: dB(A)".
