CEN/TC 19/WG 34 - Diesel cold operability correlation

CEN/TC 19/WG 34 is a Working Group within the European Committee for Standardization (CEN). It is named "Diesel cold operability correlation" and is responsible for: Study the field correlation of the different cold operability (cold flow and cloud point) test method results in relation to actual fuel performance in engines in real world cold conditions. This shall be done by: a. Performing a study into the feasibility of designing a reference fuel to be used during the (cold weather) vehicle design stage. The parameters of a reference fuel would need to be clearly defined to limit variability in fuel properties in terms of blending consistency, quality and cold flow properties b. Undertaking studies to improve technical understanding of low temperature interactions between particles in fuel and saturated monoglycerides. And to check if there is an impact on vehicle filter blocking. This committee has published 1 standards.

CEN/TC 19/WG 34 develops CEN standards in the area of Information technology.

The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.

A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
