This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes and fittings for the renovation of underground non-pressure drainage and sewerage networks by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout.
This document is applicable to plastics inner layers and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system.
NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.

This document specifies a test method to determine the resistance of a bituminous mixture or pavement to fuels. The procedure involves initial soaking of a test specimen made in the laboratory or cored from a pavement in a fuel, followed by a brushing period with a brush test device. The material loss of the specimen is a measure of the resistance to that fuel for that bituminous mixture.

This document is applicable to Resilient Element for Floating Slab system (REFS) – Elements used in floating slab and defines the test procedures and their acceptance criteria.
The document covers not only those parameters related to the effectiveness of a track structure in mitigating vibrations, that is, to reduce the emission of vibrations and structure-borne noise, but also the parameters that are needed for the static analysis and for the verification of track safety.
Floating slab track systems in the form of track base plates and track troughs are individual solutions in which there is considerable variation in the engineering design and the types of resilient elements used. For this reason, a floating slab track system is always an individual engineering solution and therefore, it is not possible to define all specific conditions for the resilient elements in the present document
The most typical types of resilient elements are:
— Full surface bearings,
— Strip bearings,
— Discrete bearings (including the helical steel spring element),
— Vertical bearings.
This document provides particular information in the following areas:
— tests methods, tests arrangements and evaluation criteria of Resilient Element for Floating Slab system,
— data supplied by the purchaser and by the supplier,
— definition of general process of homologation,
— definition of routine tests.
This document defines the specific test procedures for REFS:
— stiffness tests,
— fatigue tests,
— severe environmental condition test.
This document also sets out procedures for testing fitness for purpose and provides information on quality monitoring as part of quality assurance procedures. This document does not, however, contain requirements pertaining to the functions of Resilient Element for Floating Slab system. It is the responsibility of the purchaser to define these requirements and to choose the optional tests.
This document is not applicable for fastening system and for booted concrete block and sleeper completed with boots covered by EN 13481-5.

This document specifies test methods for determining the rates of spread and accuracy of spread of binder and chippings of a surface dressing on a section of road at a given time.
NOTE This test method can also be used for determining the rate of spread and accuracy of spread of sprayed bituminous emulsions, e.g. when used as bond coats or asphalt preservation systems. The performance categories for binder rate of spread and accuracy of spread in EN 12271 do not apply to bond coats and tack coats.
The test methods are used on site to check the ability of binder sprayers and chipping spreaders to meet the intended rates of spread and tolerances and coefficients of variation.
The test methods can be used to fulfil the Factory Production Control requirements:
— equipment calibration (EN 12271:2006, Annex B – Table B.2); and
— production inspection (EN 12271:2006, Annex B – Table B.6).
The calibration of binder and chipping spreaders requires strict application of the procedures described in this document.
Using these methods for inspections during production (FPC) allows certain changes to these methods due to the specificity of certain sites and materials used (e.g. combined chipping-binder spreaders). In this case, the changes are documented in the Factory Production Control and identified in the test reports.
Other test methods used to check the rate of spread and accuracy of spread of binder, such as the static spray bar bench test for sprayers, are not covered by this document, although the test methods in this document can be used for this purpose.

This document specifies, for anhydrous bituminous binder (fluxed bitumen or cut-back binders), the measurement of the binder aggregate adhesivity and the influence of adhesion agents or interfacial dopes and adhesion characteristics as an aid to design binder aggregate systems for surface dressing.
This document specifies methods of measurement of:
— the mechanical adhesion of the binder to the surface of the aggregate;
— the active adhesivity of the binder to the chippings;
— the improvement of the mechanical adhesion and active adhesivity by adding an adhesion agent either into the mass of the binder or by spraying the interface between binder and chippings;
— the wetting temperature of the binder to the aggregate;
— the variation of adhesivity below the fragility temperature.
The wetting capacity of the binder affects the adhesivity properties. With the presence of water, the wetting capacity of bitumen emulsion is naturally high. Even if mechanical adhesion and active adhesivity test methods are mainly dedicated to anhydrous bituminous binders (fluxed or cut-back binders), these measurements can also be practiced with bitumen emulsion with a personalized interpretation of the results that depends on the designer of the binder aggregate system. For bitumen emulsion, the conventional adhesivity is measured mainly through the water immersion test (EN 13614).
This test method is suitable for:
— bituminous binders used for surface dressings (e.g. conventional or polymer modified binders, mainly anhydrous bituminous binders, fluxed or cut-back binders, bitumen emulsions);
— all the following aggregates sizes that can be used for surface dressings:
— set 1: 2/5 mm, 5/8 mm, 8/11 mm and 11/16 mm; and
— set 2: 2/4 mm, 2/6 mm, 4/6 mm, 4/8 mm, 6/10 mm, 6/12 mm and 10/14 mm.
It is not intended that this method be used on site for quality control.
NOTE Further information concerning the purpose of the test can be found in Annex D.

This part of ISO 22476 deals with equipment requirements, the execution of and reporting on electrical cone and piezocone penetration tests.
NOTE 1 This part of ISO 22476 fulfils the requirements for electrical cone and piezocone penetration tests as part of geotechnical investigation and testing according to EN 1997 (all parts)
Within the electrical cone and piezocone penetration test, two subcategories of the cone penetration test are considered:
— electrical cone penetration test (CPT), which includes measurement of cone resistance and sleeve friction.
— electrical piezocone test (CPTU), which is a cone penetration test with the additional measurement of pore pressure.
The CPTU is performed like a CPT with the measurement of the pore pressure at one or several locations on the penetrometer surface.
NOTE 2 CPT or CPTU can also be used without measurement of sleeve friction, but this is not covered in this part of ISO 22476.
This part of ISO 22476 specifies the following features:
a) type of cone penetration test;
b) Cone penetrometer class according to Table 1;
c) Test categories according to Table 2;
d) penetration length or penetration depth;
e) elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum;
f) location of the cone penetration test relative to a reproducible fixed location reference point; and
g) pore pressure dissipation tests.
NOTE 3 This part of ISO 22476 covers onshore and nearshore CPT. For requirements for offshore CPT, see ISO 19901-8.
