Corrosion inhibitors are used extensively for pipelines in the oil and gas industry. Subcommittee G01.05 on Laboratory Corrosion Tests has been developing a series of standards on performance testing of corrosion inhibitors, including the most recently approved: ASTM G202 , Test Method for Using Atmospheric Pressure Rotating Cage. Subcommittee G01.05 is part of ASTM International Committee G01 on…

Rapid hardening hydraulic cements are used in a variety of applications in which reduced cementitious contents are desired or early service is needed. Included among these applications are paving, construction, stucco, mortar and block. A newly approved ASTM International standard covering these cements, ASTM C1600/C1600M , Specification for Rapid Hardening Hydraulic Cement, has been developed by…, Type URH, —ultra rapid hardening, for use where ultra high early strength is desired;, Type VRH, —very rapid hardening, for use where very high early strength is desired;, Type MRH, —medium rapid hardening, for use where mid-range rapid hardening, high early strength is desired; and, Type GRH, —general rapid hardening, for use when the higher strength properties of Type VRH or a Type MRH cement is not required. “ASTM C1600 lists minimum requirements for compressive strength, setting time, shrinkage and soundness (autoclave expansion),” says Hicks. “Optional specifications for sulfate expansion, alkali silicate reactions with aggregates, heat of hydration and expansion in water are also…

Manufacturers of toluene, mixed xylenes and p-xylene are often required to determine the type and amount of impurities that remain from manufacture. A new ASTM International standard, D7504 , Test Method for Trace Impurities in Monocyclic Aromatic Hydrocarbons by Gas Chromatography and Effective Carbon Number, can now be used as an internal quality control tool where these products are produced…

Localized corrosion, such as pitting, cracking or crevice corrosion, can be destructive to process equipment, but if it is detected early enough, potential damage can be minimized or avoided. A new ASTM International standard provides a means for electrochemical testing for corrosion. The new standard, G199 , Guide for Electrochemical Noise Measurement, was developed by Subcommittee G01.11 on…

A recently approved revision to ASTM International standard C 150 , Specification for Portland Cement, includes three significant technical changes to the document. The changes are part of a joint effort between ASTM and the American Association of State and Highway and Transportation Officials to harmonize C 150 with AASHTO’s standard, M 85, Specification for Portland Cement. C 150 is under the…

ASTM International Subcommittee G01.10 on Corrosion in Soils will be conducting two round robin testing procedures on Tuesday, November 14, from 9:00 a.m. to 3:00 p.m. during ASTM meetings in Atlanta, Ga. One round robin will be for the development of a new standard test method to measure the oxidation-reduction potential (redox) of soils, while the other will address precision and bias for the 4…
