Common use of GPA Standard 2377 Clause in Contracts

GPA Standard 2377. Project Co shall determine the presence of Hydrogen Sulfide (H2S) by use of GPA Standard 2377 – Test of Hydrogen Sulfide and Carbon Dioxide in Gas Using Length of Stain Tubes. Total sulfur will be determined as the summation of sulfur compounds (i.e. mercaptans) following ASTM D1988-06 (Standard Test Method for Mercaptans in Natural Gas using Length-of-Stain Detector Tubes). If the presence of Hydrogen Sulfide or sulfur compounds is detected, an additional test shall be performed to confirm the respective concentration(s) following either: (i) ASTM D6228 (Determination of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatography and Flame Photometric Detection), (ii) ASTM D5504 (Determination of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatography and Chemiluminescence), (iii) ASTM D6667 (Determination of Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases by Ultraviolet Fluorescence), or (iv) any other testing method mutually agreed by the Parties.
