This European Standard was approved by CEN on 18 November 2019.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

European foreword
This document (EN 12697-40:2020) has been prepared by Technical Committee CEN/TC 227 “Road
materials”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by August 2020, and conflicting national standards shall
be withdrawn at the latest by August 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12697-40:2012.
The following is a list of significant technical changes since the previous edition:
— the title no longer makes the method exclusively for hot mix asphalt;
— [ge] editorial update according to current standard template;
— [ge] symbol for litre, “L” amended to l;
— [6.3.8] NOTE modified according to ISO/IEC Directives – Part 2:2016, 24.5;
— [Clause 8] Test report: bullet a) completed with ambient temperature.
A list of all parts in the EN 12697 series can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
1 Scope
This document describes a method to determine the in situ relative hydraulic conductivity, at specific
locations, of a road surfacing that is designed to be permeable. An estimate of the average value for the
surfacing is obtained from the mean value of a number of determinations on each section of road.
The test measures the ability to drain water (drainability) achieved in situ of a surfacing. As such, it can
be used as a compliance check to ensure that a permeable surface course has the required properties
when it is laid. The test can also be used subsequently to establish the change of drainage ability with
time.
For the test to be valid, the surface of the test area should be clean and free from detritus.
Measurements can be made when a road is either wet or dry, but not if it is in a frozen state.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

3.1
outflow time
time (s) that elapses for an outflow of 4,0 l through the permeameter, between the meniscus at the 5 l
mark and when it falls to the 1 l mark
3.2
series resistance time
r
outflow time (s) that is determined when the permeameter is located so the outlet is clear of any
surfacing that could impede the exit of out-flowing water
Note 1 to entry: The method for calculating the series resistance time is given in Annex A.
Note 2 to entry: The series resistance time is subtracted from measurements of outflow time when the
permeameter is used on a surfacing of a pavement.
3.3
parallel leakage time
outflow time when the outlet is restricted by an impermeable surface
