Standard Test Method for Impedance and Absorption of Acoustical Materials by Impedance Tube Method

PAS 2031 can ensure that certification bodies are evaluating EEM installations in a consistent and reliable way

5 MeV to 3 MeV

or with a single binder content

installed parts and classification of surfaces

This scope and approach is illustrated in the flowchart in Figure 1 and is described in the main text of this Technical Report

the values of the track alignment parameters are chosen accordance with BS EN 13803 which helps to ensure safe riding with at least a minimum comfort level

Annex F (normative) Noise Test Code

Where CIE shares means of detection

BS EN 2240-081 shall be used together with EN 2756

The estimation of the suitability of welded connections for special service conditions

on the electric strength is taken into consideration

water must be tested on a regular basis
