A proposed new ASTM International standard will detail a multilevel approach for performing above- and below-ground inspection of transmission poles and lattice towers in the field. ASTM WK35986, Test Method for Field Inspection of Transmission Poles and Lattice Towers, will be used by utilities to provide tools for maintenance departments that inspect and repair transmission structures. ASTM…

Once approved, a proposed new ASTM International standard will aid in the evaluation of high performance protective coatings for sewerage systems. The proposed standard will provide a test specific to these coatings. Subcommittee G01.05 on Laboratory Corrosion Tests is developing ASTM WK33537 , Practice for Operating the Severe Wastewater Analysis Testing Apparatus. G01.05 is under the…, ASTM Committee G01 Next Meeting:, Nov. 16-17, 2011, November Committee Week, Tampa, Fla., Technical Contact:, Vaughn O’Dea, Tnemec Co.

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…

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…

First generation gonioapparent colorants are materials pigmented with metal flakes that change lightness as illumination angles change. Used heavily in automotive coatings, the first generation of gonioapparent materials was covered by ASTM International standard E2194 , Practice for Multiangle Color Measurement of Metal Flake Pigmented Materials, first published in 2003. Now, a second generation…

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…
