ANSI/ASA S1.18 - American National Standard Method for Determining the Acoustic Impedance of Ground Surfaces
October 31, 2018 - ASA

Outdoor sound close to the ground is influenced by the acoustical properties of the ground. This Standard describes recommended procedures to characterize, and the instruments to measure quantities that may be used to deduce, the acoustical properties of ground surfaces. Although this Standard is...

November 9, 2018 - ANSI

Scope: This American National Standard applies to instruments, systems and methods that are intended to measure the shape of the cornea of the human eye over a majority of its area. The measurements of the anterior and/or posterior surface in local areas may be of curvature and/or...

ISO 15112 - Natural gas - Energy determination
November 1, 2018 - ISO

This document provides the means for energy determination of natural gas by measurement or by calculation, and describes the related techniques and measures that are necessary to take. The calculation of thermal energy is based on the separate measurement of the quantity, either by...

DS/EN ISO 22477-5 - Geotechnical investigation and testing – Testing of geotechnical structures – Part 5: Testing of grouted anchors (ISO 22477-5:2018)
September 25, 2018 - DS

This document establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997-1 and EN 1537. Three methods of testing are recognized by this document. Test Method 1 involves cyclic tension loading with measurement of...

ASTM E1363 - Standard Test Method for Temperature Calibration of Thermomechanical Analyzers
December 1, 2018 - ASTM

This test method describes the temperature calibration of thermomechanical analyzers from −50 °C to 1500 °C. (See Note 1.) The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Warning-Mercury has been designated by many...

ASTM D4486 - Standard Test Method for Kinematic Viscosity of Volatile and Reactive Liquids
December 1, 2018 - ASTM

This test method covers the measurement of kinematic viscosity of transparent, Newtonian liquids which because of their reactivity, instability, or volatility cannot be used in conventional capillary kinematic viscometers. This test method is applicable up to 2 × 10−5 N/m2 (2 atm) pressure...
