Annotation

This method describes a means for calculating the cetane index of diesel fuels (without cetane improvers) from the aniline point, distillation, density and viscosity. The index, as computed from the prescribed formula, is termed the CGSB Cetane Index (CI).

A suggested procedure is also outlined in Appendix A to estimate the cetane index, additized (CIA), based on the calculated cetane index for diesel fuels containing diesel ignition improver (DII). This procedure can be used to estimate the combustion quality when CI and DII are used, and a cetane engine test is not performed. The Appendix A does not form a mandatory part of this method.

The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.

Методы тестирования нефти и связанных продуктов CGSB Cetane индекс дизельных топлив - Соединяющееся Исправление № 1

Этот метод описывает средство для вычисления cetane индекса дизельных топлив (без присадок для повышения цетанового числа) от анилиновой точки, дистилляции, плотности и вязкости. Индекс, как вычислено из предписанной формулы, называют Индексом Cetane (CI) CGSB.
