EN 13924-2:2014 (E) 3 Foreword This document (EN 13924-2:2014) has been prepared by Technical Committee CEN/TC 336 “Bituminous binders”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by September 2014 and conflicting national standards shall be withdrawn at the latest by December 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA which is an integral part of this document. This European Standard is part of a family of European Standards for bitumen as follows:
NOTE Industrial applications are not covered by mandate M/124. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 13924-2:2014
EN 13924-2:2014 (E) 4 Introduction This document is closely related to EN 12591. This introduction gives information on the basis for selection of the grades defined in this document, the status of certain of the properties and test methods, and proposed development of this document. The general principle adopted in the development of EN 12591 was to provide a range of grades suitable for the manufacture of the materials for road construction and maintenance used, and the climatic and traffic conditions encountered, in all the Member States. This document extends the range of grades specified in EN 12591, following the wider use of materials for road construction and maintenance. This document has been based on the regional requirements identified when the process started. It is a first step in harmonising the so-called "empirical" specifications and it is intended to evaluate alternative properties and test methods to develop new specifications that are more directly performance-related. To this end, work programmes are being undertaken and the results will be considered for a future revision of this document. The progress of those work programmes are reported in CEN/TR 15352 [1], and the results will be considered for future revisions of this European Standard. For multigrade paving grade bitumens (MG), the testing of the five essential characteristics, according to the mandate M/124, also gives an indication that its intrinsic cohesive properties are adequate for its normal use. The properties of "adhesion" and "setting ability" are indicated by tests used on the finished asphalt mixtures, EN 12697-1, EN 12697-11, EN 12697-12, EN 12697-26 (respectively [2] to [5]), rather than tests on the bitumen itself. In certain acid modified binders the structure may change when mixed with aggregate. Table B.1 lists informative properties which suppliers of multigrade bitumens are encouraged to produce as “Supplier Declared Values”. It is hoped that the data so provided will form the basis for developing performance-related specifications in the future. SIST EN 13924-2:2014

EN 13924-2:2014 (E) 6 4 Sampling Samples of bulk products shall be taken as described in EN 58. Test samples shall be taken from the laboratory samples, and prepared for testing, as described in EN 12594. 5 Requirements and test methods 5.1 General The requirements for the properties for a specific grade shall be selected from the classes given in Tables 1 and 2. The properties in Table 1 shall be specified for all multigrade paving grade bitumens. They are associated with regulatory or Health Safety and Environmental requirements. The properties in Table 2 are required to meet specific regional conditions. They are associated with regulatory or other regional requirements. When tested by the methods given in the tables, the various multigrade paving grade bitumens shall conform to the limits specified by classes in these tables. NOTE The TBR class has been included to facilitate selection in countries which merely wish to record a supplier's range for a particular requirement. It should not be considered as a "Class" for the purpose of regulatory marking. These values can be used as a basis for the development of future technical specifications. The selection of classes should be made from past experience to avoid unworkable combinations. 5.2 Properties and related test methods 5.2.1 General For specifying multigrade paving grade bitumens the appropriate class for each technical requirement is selected in turn. Different classes may be selected for different properties. 5.2.2 Consistency at intermediate service temperature Consistency at intermediate service temperature for these multigrade paving grade bitumens shall comply with the requirements for penetration at 25 °C in Table 1. 5.2.3 Consistency at elevated service temperature Consistency at elevated service temperature for these multigrade paving grade bitumens shall comply with the requirements for softening point Ring and Ball in Table 1. 5.2.4 Temperature dependence of consistency Temperature dependence of consistency shall comply with the requirements for penetration index (Ip) in Table 1. Where required, multigrade paving grade bitumens shall comply also with the requirement for dynamic viscosity in Table 2. The penetration index shall be calculated in accordance with Annex A. 5.2.5 Brittleness at low service temperature Brittleness at low service temperature may be required to meet specific regional conditions. Where required, multigrade paving grade bitumens shall conform to the requirements for Fraass breaking point in Table 2. SIST EN 13924-2:2014
EN 13924-2:2014 (E) 7 5.2.6 Durability – Resistance to hardening Durability shall be demonstrated by compliance with the required surrogate characteristics “Resistance to hardening“ of Table 1. Resistance to hardening shall be tested after running the Rolling Thin Film Oven Test (RTFOT), EN 12607-1. NOTE Appropriate tests and classes, for measurements on material after the hardening procedure, are given in Table 1. The choice of class may depend upon the intended use of the product. 5.2.7 Temperature dependency of mixing Where required, multigrade paving grade bitumens shall comply also with the requirement for kinematic viscosity in Table 2. 5.2.8 Other properties 5.2.8.1 Flash point Flash point shall be determined by the Cleveland open cup method in EN ISO 2592. NOTE The Pensky-Martens closed cup method (see EN ISO 2719 [8]) can be used to investigate possible contamination, but is likely to give lower values. 5.2.8.2 Density If the supplier wishes to declare the density of multigrade paving grade bitumens, it shall be determined in accordance with EN 15326. 5.2.8.3 Solubility Solubility shall be determined on the fresh multigrade paving grade bitumens in accordance with EN 12592. 5.2.9 Informative properties The specifications include a table of informative properties (Annex B) based on new test methods. Suppliers of multigrade paving grade bitumens are invited to supply data from these measurements to the client on a voluntary basis. It is hoped that the data so gathered will be of assistance in developing performance-related specifications in the future. 5.3 Release of regulated dangerous substances When required, products covered by this standard shall comply with relevant regulations on dangerous substances in force in the intended place of use. In the absence of International or European test methods, manufacturers shall verify and declare the release of dangerous substances in accordance with provisions applicable in the intended place of use of the product.

The reference method is EN 12596. 6 Assessment and verification of constancy of performance - AVCP 6.1 General The compliance of multigrade paving grade bitumens with the requirements of this standard and with the performance declared by the manufacturer in the declaration of performance (DoP) shall be demonstrated by: — Determination of the product type; — Factory Production Control (FPC) by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s) NOTE The information from AVCP can be available for audit as detailed in a manufacturer's quality plan. 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g. use of previously existing data, classified without further testing (CWFT) and conventionally accepted performance). Assessment previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for the same characteristics for all products within that same family SIST EN 13924-2:2014
EN 13924-2:2014 (E) 10 Products may be grouped in different families for different characteristics. With reference to the assessment method, standards should be made to allow the selection of a suitable representative sample. In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance: — at the beginning of the production of a new or modified multigrade paving grade bitumen (unless a member of the same product range), or — at the beginning of a new or modified method of production (where this may affect the stated properties); or they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the multigrade paving grade bitumen design, in the raw material or in the supplier of the components, or in the method of production (subject to the definition of a family), which would affect significantly one or more of the characteristics. Where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of assessment methods of other product standards, these characteristics need not be re-assessed. The specifications of these components shall be documented. Products bearing regulatory marking in accordance with appropriate harmonized European specifications may be presumed to have the performances declared in the declaration of performance (DoP), although this does not replace the responsibility on the multigrade paving grade bitumen manufacturer to ensure that the multigrade paving grade bitumen as a whole is correctly manufactured and its component products have the declared performance values. 6.2.2 Test samples, testing and compliance criteria Sampling shall be carried out in accordance with Clause 4. The results of all type tests shall be recorded, held by the manufacturer at least ten years from the date of the test or until the type test is no longer valid (whichever is the longer) and be available for inspection. 6.2.3 Test reports The results of the determination of the product type shall be documented in test reports. All test reports shall be retained by the manufacturer for at least 10 years after the last date of production of the multigrade paving grade bitumen to which they relate. 6.2.4 Shared other party results A manufacturer may use the results of the product type determination obtained by someone else (e.g. by another manufacturer, as a common service to manufacturers, or by a product developer), to justify his own declaration of performance regarding a product that is manufactured according to the same design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same kind, provided that: — the results are known to be valid for products with the same essential characteristics relevant for the product performance; — in addition to any information essential for confirming that the product has such same performances related to specific essential characteristics, the other party who has carried out the determination of the product type concerned or has had it carried out, has expressly accepted to transmit to the manufacturer the results and the test report to be used for the latter’s product type determination, as well as information regarding production facilities and the production control process that can be taken into account for FPC; SIST EN 13924-2:2014
EN 13924-2:2014 (E) 11 — the manufacturer using other party results accepts to remain responsible for the product having the declared performances and he also: — ensures that the product has the same characteristics relevant for performance as the one that has been subjected to the determination of the product type, and that there are no significant differences with regard to production facilities and the production control process compared to that used for the product that was subjected to the determination of the product type, and — keeps available a copy of the determination of the product type report that also contains the information needed for verifying that the product is manufactured according to the same design and with raw materials, constituents and manufacturing methods of the same kind. 6.3 Factory production control (FPC) 6.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market comply with the declared performance of the essential characteristics. The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product. All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic

Introduction
This document is closely related to EN 14023 [1]. This introduction gives information on the basis for selection
of the grades defined in this document, the status of certain of the properties and test methods, and proposed
development of this document.
The general principle adopted in the development of EN 14023 [1] was to provide a range of grades suitable
for the manufacture of the materials for road construction and maintenance used, and the climatic and traffic
conditions encountered, in all the Member States. This document extends the range of grades specified in EN
14023 [1], following the wider use of materials for road construction and maintenance.
This document has been based on the regional requirements identified when the process started. It is a first
step in harmonising the so-called "empirical" specifications and it is intended to evaluate alternative properties
and test methods to develop new specifications that are more directly performance-related. To this end, work
programmes are being undertaken and the results will be considered for a future revision of this document.
The progress of those work programmes are reported in CEN/TR 15352 [2], and the results will be considered
for future revisions of this European Standard.
For multigrade paving grade bitumens (MG), the testing of the five essential characteristics, according to the
mandate M/124, also gives an indication that its intrinsic cohesive properties are adequate for its normal use.
The properties of "adhesion" and "setting ability" are indicated by tests used on the finished asphalt mixtures,
EN 12697–1, EN 12697–11, EN 12697–12, EN 12697– 26 (respectively [3] to [6]), rather than tests on the
bitumen itself.
Multigrade bitumens are designated by mentioning MG and the penetration range at 25 °C,followed by the
softening point range (see Table 1A). e.g. MG 20/30-63/72.
Table B.1 (Annex B) lists informative properties which suppliers of multigrade bitumens are encouraged to
produce as “Supplier Declared Values”. It is hoped that the data so provided will form the basis for developing
performance-related specifications in the future.

prEN 13924-2:2011 (E)
Test samples shall be taken from the laboratory samples, and prepared for testing, as described in EN 12594.
5 Requirements and test methods
5.1 General
The requirements for the properties for a specific grade shall be selected from the classes given in Table 1A
and 1B. The properties in Table 1A shall be specified for all multigrade bitumens. They are associated with
regulatory or HSE requirements. The properties in Table 1B are required to meet specific regional conditions.
They are associated with regulatory or other regional requirements.
When tested by the methods given in the tables, the various paving grades shall conform to the limits
specified by classes in that table.
NOTE. The TBR class has been included to facilitate selection in countries which merely wish to record a
supplier's range for a particular requirement. It should not be considered as a "Class" for the purpose of
regulatory marking. These values can be used as a basis for the development of future technical
specifications.
The selection of classes should be made from past experience to avoid unworkable combinations.
5.2 Properties and related test methods
5.2.1 General
For specifying multigrade bitumens the appropriate class for each technical requirement is selected in turn.
Different classes may be selected for different properties.
5.2.2 Consistency at intermediate service temperature
Consistency at intermediate service temperature for these multigrade bitumens shall comply with the
requirements for penetration at 25 °C in Table 1A.
5.2.3 Consistency at elevated service temperature
Consistency at elevated service temperature for these multigrade bitumens shall comply with the
requirements for softening point Ring and Ball in Table 1A.
5.2.4 Temperature dependence of consistency
Temperature dependence of consistency shall comply with the requirements for penetration index (I ) in
p
Table 1A. Where required, multigrade bitumens shall conform also to the requirement for kinematic viscosity
and/or dynamic viscosity in Table 1B.
The penetration index shall be calculated in accordance with Annex A.
5.2.5 Brittleness at low service temperature
Brittleness at low service temperature may be required to meet specific regional conditions. Where required,
multigrade bitumens shall conform to the requirements for Fraass breaking point in Table 1B.
5.2.6 Durability – Resistance to hardening
Durability shall be demonstrated by compliance with the required surrogate characteristics of Table 1A.

---------------------- Page: 8 ----------------------
oSIST prEN 13924-2:2011
prEN 13924-2:2011 (E)
Resistance to hardening shall be tested according to the Rolling Thin Film Oven Test (RTFOT) (EN 12607-1).
NOTE 1 Appropriate tests and classes, for measurements on material after the hardening procedure, are given in
Table 1A. The choice of class may depend upon the intended use of the product.
5.2.7 Other properties
5.2.7.1 Flash point
Flash point shall be determined by the Cleveland open cup method in EN ISO 2592.
NOTE The Pensky-Martens closed cup method (see EN ISO 2719 [9]) can be used to investigate possible
contamination but is likely to give lower values.
5.2.7.2 Density
If the supplier wishes to declare the density of multigrade bituminous binders it shall be determined in
accordance with EN 15326+A1.
5.2.7.3 Solubility
Solubility shall be determined on the fresh multigrade bitumen in accordance with EN 12592.
5.2.8 Informative properties
The specifications include a table of informative properties (Annex B) based on new test methods. Suppliers
of multigrade bitumens are invited to supply data from these measurements to the client on, a voluntary basis.
It is hoped that the data so gathered will be of assistance in developing performance-related specifications in
the future.
5.3 Release of dangerous regulated substances
Materials used in products shall not release any dangerous substances in excess of the maximum permitted
levels specified in a relevant European standard for the material or permitted in national regulations of the
member state of destination.
5.4 Precision and dispute
The test methods referred to in this document include a precision statement where available. In cases of
uncertainty, the procedures described in EN ISO 4259 for interpretation of the results based on test method
precision shall be used.
