ASTM D8297/D8297M - Standard Test Method for Determination of Erosion Control Products (ECP) Performance in Protecting Slopes from Sequential Rainfall-Induced Erosion Using a Tilted Bed Slope
May 15, 2020 - ASTM

This test method is used to evaluate the ability of erosion control products (ECP) to protect slopes from rainfall-induced erosion using an adjustable tilting bed slope. The standard slopes range from 2:1 to 4:1 (H:V) having a target rainfall intensity of 3.5 in./h [90 mm/h]. There are three main...

ASTM D7181 - Standard Test Method for Consolidated Drained Triaxial Compression Test for Soils
January 1, 2020 - ASTM

This test method covers the determination of strength and stress-strain relationships of a cylindrical specimen of either intact or reconstituted soil. Specimens are consolidated and sheared in compression with drainage at a constant rate of axial deformation (strain controlled). This test method...

ASTM D5240/D5240M - Standard Test Method for Evaluation of the Durability of Rock for Erosion Control Using Sodium Sulfate or Magnesium Sulfate
January 1, 2020 - ASTM

This test method covers test procedures for evaluating the soundness of rock for erosion control by the effects of a sodium or magnesium sulfate solution on slabs of rock. It is an accelerated weathering test. The rock slabs, prepared in accordance with procedures in Practice D5121, are intended to...

ASTM D558/D558M - Standard Test Methods for Moisture-Density (Unit Weight) Relations of Soil-Cement Mixtures
December 1, 2019 - ASTM

These test methods cover the determination of the relationship between the water content and the density of soil-cement mixtures when compacted before cement hydration as prescribed. A 0.0333-ft3 [944-cm3] mold and a 5.50-lbf [24.5-N or mass of 2.5-kg] rammer dropped from a height of 12.0 in. [30.5...

API TR 684-1 - API Standard Paragraphs Rotordynamic Tutorial: Lateral Critical Speeds, Unbalance Response, Stability, Train Torsionals, and Rotor Balancing
November 1, 2019 - API

Introduction This document is intended to describe, discuss, and clarify the API Standard Paragraphs (SP) Section 6.8 which outlines the complete lateral and torsional rotordynamics and rotor balancing acceptance program designed by API to ensure equipment mechanical reliability. Background...

ASTM D8296 - Standard Test Method for Consolidated Undrained Cyclic Direct Simple Shear Test under Constant Volume with Load Control or Displacement Control
November 1, 2019 - ASTM

This test method defines equipment specifications and testing procedures for the measurement of cyclic strength, number of cycles to liquefaction or cyclic properties (Modulus and Damping) of soils, after one-dimensional consolidation using a cyclic mode of loading. The cyclic shearing can be...

ASTM C1363 - Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus
September 1, 2019 - ASTM

This test method establishes the principles for the design of a hot box apparatus and the minimum requirements for the determination of the steady state thermal performance of building assemblies when exposed to controlled laboratory conditions. This method is also used to measure the thermal...

ASTM D4829 - Standard Test Method for Expansion Index of Soils
September 1, 2019 - ASTM

This test method allows for determination of expansion potential of soils when inundated with distilled water.2 This test method measures a qualitative index property of the soil rather than a design parameter to be used for calculation of the actual amount of expansion. The expansion index, EI,...

ASTM D4729 - Standard Test Method for In Situ Stress and Modulus of Deformation Using the Flat Jack Method
June 1, 2019 - ASTM

The flat jack test measures the natural or altered in situ stress at a rock surface either for a surface outcrop or an underground excavation surface. The modulus of deformation and the long-term deformational properties (creep) may also be evaluated for the applied stress range, however long-term...
