ASTM D6421-19 - Standard Test Method for Evaluating Automotive Spark-Ignition Engine Fuel for Electronic Port Fuel Injector Fouling by Bench Procedure
November 1, 2019 - ASTM International

5.1 Driveability problems in PFI automobiles were first reported in 1984. Deposits are prone to form on the metering surfaces of pintle-type electronic fuel injectors. These deposits reduce fuel flow through the metering orifices. Reductions in metered fuel flow result in an upset in...

ASTM E2677-20 - Standard Test Method for Estimating Limits of Detection in Trace Detectors for Explosives and Drugs of Interest
February 1, 2020 - ASTM International

1.1 In harmony with the Joint Committee for Guides in Metrology (JCGM) and detection concepts of the International Union of Pure and Applied Chemistry (IUPAC) (1, 2)2, this test method uses a series of replicated measurements of an analyte at dosage levels giving...

ASTM C780-19 - Standard Test Method for Preconstruction and Construction Evaluation of Mortars for Plain and Reinforced Unit Masonry
December 15, 2019 - ASTM International

5.1 During preconstruction and construction evaluations, use of these test methods establishes specific and overall performance characteristics for the mortar system. 5.2 Preconstruction testing of mortars prebatched by weight provides information for the selection of the...

ASTM C1550-19 - Standard Test Method for Flexural Toughness of Fiber Reinforced Concrete (Using Centrally Loaded Round Panel)
October 1, 2019 - ASTM International

1.1 This test method covers the determination of flexural toughness of fiber-reinforced concrete expressed as energy absorption in the post-crack range using a round panel supported on three symmetrically arranged pivots and subjected to a central point load. The performance...

ASTM C692-13(2018) - Standard Test Method for Evaluating the Influence of Thermal Insulations on External Stress Corrosion Cracking Tendency of Austenitic Stainless Steel
November 1, 2018 - ASTM International

5.1 An inherent characteristic of some alloys of austenitic stainless steel is their tendency to crack at stress points when exposed to certain corrosive environments. The mechanisms of ESCC are complex and not completely understood but are apparently related to certain...

ASTM C1764-12(2018) - Standard Test Methods for Non Metallic Plaster Bases (Lath) Used with Portland Cement Based Plaster in Vertical Wall Applications
October 1, 2018 - ASTM International

1.1 These test methods evaluate the performance of vertical wall applications of non metallic plaster bases used with Portland Cement Based Plaster under a variety of test exposures. 1.2 Units-The values stated in either SI units or inch-pound units are to be regarded...

Earthquakes and Tsunamis Are Potent Disasters, UN Says
October 1, 2018 - IEEE GlobalSpec

A 7.5-magnitude earthquake and resultant tsunami which struck Sulawesi, Indonesia, on Sept. 28 led the United Nations to issue a reminder that the Pacific's Ring of Fire is the planet's most active seismic zone. As such, it requires special attention when it comes to disaster risk...

ASTM E1921-19b - Standard Test Method for Determination of Reference Temperature, T o , for Ferritic Steels in the Transition Range
July 15, 2019 - ASTM International

1.1 This test method covers the determination of a reference temperature, To, which characterizes the fracture toughness of ferritic steels that experience onset of cleavage cracking at elastic, or elastic-plastic KJc instabilities, or both. The specific types of...
