General:
This test method covers the determination of the corrosiveness of automotive spark-ignition engine fuels (e.g., gasoline) toward silver and silver alloys. It uses a thin silver strip to detect the presence of corrosive sulfur compounds that can tarnish or corrode silver components in fuel systems, such as fuel gauge senders.
Precision:
The method provides repeatability and reproducibility statements based on interlaboratory studies. Results are reported as a corrosion rating. Precision data are detailed in the full standard for different rating levels.
