Standard Test Method for Corrosiveness to Silver by Automotive Spark–Ignition Engine Fuel–Silver Strip Method
N D7671
Annotation
This test method covers the determination of the corrosiveness to silver by automotive spark-ignition engine fuel, as defined by Specification D4814, or similar specifications in other jurisdictions, having a vapor pressure no greater than 124 kPa (18 psi) at 37.8 °C (100 °F), by one of two procedures. Procedure A involves the use of a pressure vessel, whereas Procedure B involves the use of a vented test tube.
The result of the test is based on a visual rating that is classified as an integer in the range from 0 to 4 as defined.
The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Метод стандартной пробы для коррозионной активности к серебру автомобильным топливным серебром двигателя с принудительным зажиганием раздевает метод
Этот метод тестирования покрывает определение коррозионной активности к серебру автомобильным топливом механизма воспламенения искры, как определено Спецификацией D4814 или подобными спецификациями в других юрисдикциях, имея давление пара, не больше, чем 124 кПа (18 фунтов на квадратный дюйм) в 37.8 °C (100 °F), одной из двух процедур. Процедура A включает использование камеры высокого давления, тогда как Процедура B включает использование вентилируемой пробирки.
