Active Standard: E904 - 87(2007)
This standard is being balloted for withdrawal with no replacement because this standard does not offer any true insights into how to conduct an all-day performance test. Any reasonably well-informed, technical person could develop a custom test program that would intuitively be in line with this standard.
