ASTM G200 - STANDARD TEST METHOD FOR MEASUREMENT OF OXIDATION-REDUCTION POTENTIAL (ORP) OF SOIL Organization: ASTM
Date: 2009-05-01
Description: This test method covers a procedure and related test equipment for measuring oxidation-reduction potential (ORP) of soil samples removed from the ground. The procedure in Section 9 is appropriate for field and laboratory measurements.
GOST R 8.702 - STATE SYSTEM FOR ENSURING THE UNIFORMITY OF MEASUREMENETS. MEASURING ELECTRODES FOR OXIDATION-REDUCTION POTENTIAL DETERMINATION (ORP). VERIFICATION PROCEDURE Organization: GOST
Date: 2010-01-01
GOST 8.639 - RUSSIAN LANGUAGE - STATE SYSTEM FOR ENSURING THE UNIFORMITY OF MEASUREMENTS. MEASURING ELECTRODES FOR OXIDATION - REDUCTION POTENTIAL DETERMINATION (ORP). VERIFICATION PROCEDURE Organization: GOST
SAE/TP - 2007-01-3095 - EVALUATION OF THERMOPHILIC AEROBIC DIGESTION FOR WASTE TREATMENT Organization: SAE/TP
Date: 2007-07-09
Description: The primary objectives of this research included the evaluation of the system, including effects of influent solids loadings, hydraulic retention time, oxygen transfer, and the influence of operational parameters such as pH, ORP, and temperature. Investigation into the effect of mechanical changes in the system on oxygen transfer was evaluated.
ASTM D1498 - STANDARD TEST METHOD FOR OXIDATION-REDUCTION POTENTIAL OF WATER Organization: ASTM
Date: 2014-02-15
Description: This test method covers the apparatus and procedure for the electrometric measurement of oxidation-reduction potential (ORP) in water. It does not deal with the manner in which the solutions are prepared, the theoretical interpretation of the oxidation-reduction potential, or the establishment of a standard oxidation-reduction potential for any given system.
SAE/TP - 2008-01-1981 - INITIAL ENGINEERING MODEL DEVELOPMENT FOR SULFATE REDUCING BACTERIA COLONIZATION POTENTIAL RELATED TO FORWARD CONTAMINATION AND ECOSYNTHESIS Organization: SAE/TP
Date: 2008-06-29
Description: Specifically, proof of concept testing was conducted at a temperature of 4ºC ± 0.15ºC, a salt concentration 2.5% as NaCl (simulated marine salt water), a pH range of 7.8 to 8.5, and an oxidation-reduction potential (ORP) of approximately - 480mV using a Pt electrode (equivalent to -280mV using a standard H+ electrode).
API PUBL 4657 - EFFECTS OF SAMPLING AND ANALYTICAL PROCEDURES ON THE MEASUREMENT OF GEOCHEMICAL INDICATORS OF INTRINSIC BIOREMEDIATION: LABORATORY AND FIELD STUDIES Organization: API
Date: 1997-11-01
Description: These include dissolved oxygen (DO), nitrate, sulfate, ferrous iron, methane, carbon dioxide, alkalinity, oxidation/reduction potential (ORP), pH, conductivity, and temperature. Measurement of these parameters is being performed at an increasing number of petroleum hydrocarbon sites.
