escapes rapidly when exposed to air. Never leave sample containers uncapped, and minimize fuel agitation during the initial pouring phase.

The ASTM D5705 test method is specifically tailored for residual fuel oils, which are heavy, highly viscous petroleum products. Core Methodology
ASTM D1293 is for pH measurement of water — unrelated. Always double-check the number. astm d5705 pdf
A "length of stain" detector tube (often lead acetate based) and a hand-operated pump are used to measure the H2Scap H sub 2 cap S concentration in the vapor space. Limitations and Correlations
Some university engineering departments purchase "ASTM Student Editions" or have site licenses. Major metropolitan libraries sometimes offer free access to ASTM standards for reading online (though printing may be restricted). Call your local engineering library to ask about "ASTM reading room access."
The detection relies on a simple yet effective precipitation reaction. When H2Scap H sub 2 cap S passes through lead acetate ( ) impregnated in the tube, it forms lead sulfide ( PbScap P b cap S ), which is black or brown: escapes rapidly when exposed to air
