The scope of this document is constrained to the content of the electronic prescription (ePrescription) itself, the digital document which is issued by a prescribing healthcare professional and received by a dispensing healthcare professional. The prescribed medicinal product is to be dispensed through an authorized healthcare professional with the aim of being administered to a human patient. The ePrescription in the administrative workflow of reimbursement is not covered in this document.
This document specifies the requirements that apply to ePrescriptions. It describes generic principles that are considered important for all ePrescriptions.
This document is applicable to ePrescriptions of medicinal products for human use. Although other kinds of products (e.g. medical devices, wound care products) can be ordered by means of an ePrescription, the requirements in this document are aimed at medicinal products that have a market authorization and at pharmaceutical preparations which are compounded in a pharmacy.
This document does not limit the scope to any setting (community, institutional) and leaves it to the national bodies to decide on this matter.
This document specifies a list of data elements that can be considered as essential for ePrescriptions, depending on jurisdiction or clinical setting (primary healthcare, hospital, etc.). Ensuring the authenticity of these data elements is in scope and will have impact on the requirements of information systems.
Other messages, roles and scenarios (e.g. validation of a prescription, administration, medication charts, EHR of the patient, reimbursement of care and dispensed products) are not covered in this document, because they are country-specific or region-specific, due to differences in culture and in legislation of healthcare. However, requirements and content of ePrescriptions within the context of jurisdictions have a relationship with these scenarios. This document also does not cover the way in which ePrescriptions are made available or exchanged, and the process of prescribing itself.
The logistic process of prescribing itself is not part of the scope. A prescription can either be sent (pushed) to a dispenser or either be retrieved (pulled) at the dispenser. However, the requirement for the prescription is described, that it will be able to function in both environments.

This document explains the requirements and test methods for paraffinic diesel fuel from synthesis or hydrotreatment. Synthesis refers to XTL processes where X refers to various feedstocks for example Gas (G), Biomass (B) or Coal (C) and TL stands for To-Liquid. Hydrotreatment of vegetable oils and animal fats yield Hydrotreated Vegetable Oil (HVO). Paraffinic diesel fuel can be blended with up to 7,0 % (V/V) fatty acid methyl ester (FAME). This document provides background information to the final text of EN 15940 [1] and gives guidance and explanations to the producers, blenders, marketers and users of paraffinic automotive diesel fuel.
Paraffinic diesel fuel is a high quality, clean burning fuel with virtually no sulfur and aromatics. Paraffinic diesel fuel can be used in diesel engines, also to reduce regulated emissions. In order to have the greatest possible emissions reduction, a specific calibration is needed. Some types of paraffinic diesel fuel, at present notably HVO, can also offer a meaningful contribution to the target of increased non-crude derived and/or renewable content in the transportation fuel pool.
For general diesel engine operation, durability and warranty, paraffinic automotive diesel fuel needs a validation step to confirm the compatibility of the fuel with the vehicle, which for some existing engines still needs to be done. The vehicle manufacturer needs to be consulted before use.
NOTE 1   This document is directly related to EN 15940 and will be updated once further publications take place.
NOTE 2   Paraffinic diesel fuel is also used as a blending component in automotive diesel fuel. In that case, composition and properties of the final blends are defined by relevant fuel specification standards.
NOTE 3   For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.
