European foreword

This document (prEN 16734:2021) has been prepared by Technical Committee CEN/TC 19 “Gaseous

and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the

secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16734:2016+A1:2018.

This document has originally been prepared under a mandate [1] given to CEN by the European

Commission and the European Free Trade Association. It has been developed in coordination with

representatives of those institutions.

This document describes a specification for diesel fuel containing up to 10,0 % (V/V) Fatty Acid Methyl

Ester. This product is not suitable for all vehicles, so consumers and providers should consult vehicle

manufacturers or manuals before use.

Requirements following amendment 2003/17/EC [3], 2009/30/EC [4], 2011/63/EU [5] and

2014/77/EU [6] to the European Fuels Quality Directive 98/70/EC [2], are taken into account. Dates

are included with all normative test method references in order to comply with the requirements of the

European Commission; with the accompanying assurance by CEN/TC 19 that any referenced updated

versions will always give at least the same accuracy and at least the same level of precision (see [4]).

The marking at the pump of this product is in line with the requirements of the Fuels Quality Directive

and the Alternative Fuels Infrastructure Directive [7].

Significant technical changes between this document and the previous edition are:

— Inclusion of the amended EN 14214 FAME specification.

— Update to the normative references towards undated versions where they don't concern

requirements originating from European Directives (in line with decisions by CEN/TC 19 in

coordination with the European Commission), and updating the effective publication dates were

required.

— Deletion of the Fuel Ignition Tester (EN 16144) as an alternative test method for cetane number

determination due to its absence of use in the market. Whereas the BASF engine (EN 16906) and

the ICN technique (EN 17155) have now been included as alternative methods for cetane number

determination,

— Addition of micro-distillation (EN 17306) as an alternative test method to distillation by

EN ISO 3405 and EN ISO 3924.

— Addition of automated method (EN ISO 22995) as an alternative test method to cloud point by

EN ISO 3015.

— Addition of the Stabinger viscometer (ISO 23581) as an alternative test method to viscosity by

EN ISO 3104.

— Addition of oxidation stability by rapid small scale oxidation method (EN 16091) as an alternative

test method to oxidation stability by EN 15751 for diesel fuel containing FAME above 2,0 % (V/V).

---------------------- Page: 5 ----------------------
oSIST prEN 16734:2021
prEN 16734:2021 (E)

— Deletion of Annex A on precision data and introduction of a NOTE under 6.5.1 in relation to test

method precision data for diesel fuel containing FAME.

— Update to the 'workmanship clause' in 6.5.3 to address the issue of abrasive wear of fuel injection

equipment by hard particles in diesel fuel.

— Introduction of further clarification around the lubricity requirement in Table 1.

— Reduction of the minimum density limit for Grades D, E and F, moving the property from Table 1

to Table 2.
— Clarification of the dispute requirement concerning sulfur content in 6.7.3.
— Deletion of the allowance for cetane alternative methods in 6.7.4.

— Addition of 6.7.11 to address situations in which the test method includes a bias-correction to the

dispute method.

— Deletion of the A-deviation for Belgium following change of national legislation.
