Foreword
GB/T 28950 "Road vehicles and internal combustion engines cleaner terminology" is divided into two parts.
--- Part 1. definitions of filters and filter components;
--- Part 2. Filters and components defined performance indicators.
This is Part 2 GB/T 28950 of.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This section uses the translation method identical with the international standard ISO 11841-2:2000 "Road vehicles and internal combustion engines cleaner terminology Part 2. Filters and components defined performance indicators "(in English).
This part made the following editorial changes.
--- Original International Standard. 3 filters and their components performance classification, 4 filters and component performance is defined by the terms of the formula chart to Syria Said; wherein "unit" normative specification into a separate list in Appendix A, said, "Remarks" column to "comment" column.
This part is proposed by the National Development and Reform Commission.
This part of the National Automotive Standardization Technical Committee (SAC/TC114) centralized.
