Determining the pressure rating for PVC plastic pipe is a relatively straightforward process because pipe is a cylinder with a uniform wall thickness. However, establishing a pressure rating for PVC fittings is a more complex process, chiefly because there are many sizes, patterns and variations among manufacturers involved. A new ASTM International standard, F 2261 , Test Method for Pressure…

Keeping pipes properly connected is clearly an important aspect of any sewer maintenance system. A new ASTM International standard, F 2561 , Practice for Rehabilitation of a Sewer Service Lateral and Its Connection to the Main Using a One-Piece Main and Lateral Cured-in-Place Liner, has been developed that makes the process of keeping sewer pipelines connected more effective. Practice F 2561 is…

ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications will hold its annual mini-symposium on Jan. 24, 2006, at the Embassy Suites Hotel in Ft. Lauderdale, Fla. The focus of the sessions will be on the role and use of statistics in the development of standard test methods, with emphasis on recent developments. The following three lectures will be given during…, Statistical Requirements Inside and Outside ASTM International, Many coatings and raw material manufacturers have registered to the ISO 9002 standard. That standard has been replaced by ISO 9001:2000, with the requirements for the new standard being more extensive. However, some of the new requirements can be met by using basic statistical techniques. This presentation, which will be given by Robert Morrison, is an overview of the new requirements and compare…, The Use of Ranked vs. Rated Data in the Evaluation of Weathered Specimens or Material, The evaluation of specimens after weathering can be handled by a number of approaches; two of these are rating and ranking. Rating requires one to compare the specimens against a scale (i.e., 1 to 10). Ranking, on the other hand, requires the direct comparison of the specimens against each other. Louis Asher will make this presentation, which will center on these two approaches and will…, ASTM International Interlaboratory Study Program, ASTM International recently approved a new Interlaboratory Study Program. Through this program, ASTM is providing staff support and financial resources to technical committees by offering assistance with the identification of participating laboratories, overseeing the generation of sample distribution, collecting data, and generating precision and bias statements and research reports. This…

ASTM International Subcommittee D01.23 on Physical Properties of Applied Paint Films has approved three new standards that each deal with different types of measurements for paint coatings. Subcommittee D01.23 is under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications. Titles and descriptions of each new standard follow. , D 6991, Test Method for Internal Stresses in Organic Coatings by Cantilever (Beam) Method, Test Method D 6991 covers the procedure for measuring internal stresses in organic coatings by using the cantilever (beam) method. The test method can be used to determine the internal stresses in coatings after they have cured. Most organic coatings shrink when they cure. This induces an internal stress in the coatings. If the substrate is flexible, such as a vinyl composition tile, and has…, D 7091, Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Nonferrous Metals, The development of D 7091 is the result of subcommittee discussions on the need to revise or replace D 1186, Test Method for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to a Ferrous Base, and D 1400, Test Method for Nondestructive Measurement of Dry Film Thickness of Nonconductive Coatings Applied to a Nonferrous Metal Base. Rather than revising or…, D 7187, Test Method Measuring Mechanical Aspects of Scratch/Mar Behavior of Paint Coatings by Nanoscratching, Test Method D 7187 determines the resistance to mar and scratch of paint coatings on smooth, flat surfaces. The standard, which had its origin in a paper presented by Li Lin, DuPont, at the 2002 Committee D01 Centennial symposium on new directions in coatings performance technology, is a possible solution to recent searches within the automotive industry for a better way to measure the scratch…

ASTM International Committee C24 on Building Seals and Sealants is currently working to fill a need for a weatherproofing sealant field test standard. The result, proposed standard WK7800, Guide for a Non-Destructive, Continuous, Field Test of Installed Weatherproofing Sealant, features a field test that has been used by sealant professionals for years, but has not, up to this point, been…

A growing interest in a more durable structure for grease traps has resulted in the development of a proposed new ASTM standard, WK7686, Specification for High Density Polyethylene Grease Trap Interceptor Units. The proposed standard is under the jurisdiction of ASTM Subcommittee F17.26 on Olefin Based Pipe, which is part of Committee F17 on Plastic Piping Systems. "The impetus for developing…

A new ASTM standard developed by Committee F17 on Plastic Piping Systems will be an important step in advancing the use of high density polyethylene pipe in municipal storm sewer applications. The standard, F 2306, Specification for 12 to 60 in. (300 to 1500 mm) Annular Corrugated Profile Wall Polyethylene (PE) Pipe and Fittings for Gravity Flow Storm Sewer and Subsurface Drainage Applications,…

ASTM International Task Group D01.42.20 is soliciting participants to conduct a round robin to evaluate the precision of ASTM standard D 4446, Test Method for Anti-Swelling Effectiveness of Water-Repellent Formulations and Differential Swelling of Untreated Wood When Exposed to Liquid Water Environments. This standard is commonly known as the wood swellometer test and is widely used by…

ASTM International Committee C24 on Building Seals and Sealants is now working on a proposed new standard, WK6920, Fatigue Resistance of Structural Silicone. The standard, which is under the jurisdiction of ASTM Subcommittee C24.20 on General Sealant Standards, is intended to serve as an enhancement to current performance requirements for structural silicones and to help users ascertain that…

In the past, the only measurement used to determine whether sealants could endure a great deal of foot traffic was hardness. Because research presented at symposia and from the field has shown that other factors need to be considered in the design and use of traffic sealants, ASTM International Committee C24 on Building Seals and Sealants has a new proposed standard that encompasses a wider range…
