📐 Channel Geometry and Cross-Section Requirements ASTM D5388-21 provides a standard test method for computing the discharge of water in open channels using the step-backwater method. This computation relies heavily on precisely defined cross-sectional characteristics. Cross sections are numbered consecutively…

📐 Scope and Application ASTM D5387-93 (Reapproved 2019), formally titled the Standard Guide for Elements of a Complete Data Set for Non-Cohesive Sediments, establishes the essential criteria for collecting and documenting sediment and hydraulic data. The primary objective is to…

📐 Specimen Geometry and Preparation The test substrate consists of precast concrete patio blocks with a minimum density of 2000 kg/m³ [125 lb/ft³] and minimum compressive strength of 14.5 MPa [2100 psi]. Each block measures 191±12 by 394±12 by 57±6…

ASTM D5386-24 specifies an instrumental method for determining the color of near-clear liquids using CIE tristimulus colorimetry, with results expressed on the platinum-cobalt (Pt-Co) scale. This method is designed for clear, haze-free liquids with Pt-Co values in the 0 to…

📋 Standard D5384 Scope and Core Methodology ASTM D5384-14 specifies field test kit methods for determining total chlorine concentration in used petroleum products (crankcase, hydraulic, diesel, lubricating, and fuel oils, as well as kerosene). The method is strictly limited to…

🎨 Overview and Scope ASTM D5383-16 (Reapproved 2021) offers a straightforward practice for artists and art technologists to visually assess the lightfastness of colored art materials. The method involves exposing specimens to sunlight through a closed window, simultaneously exposing a…

This guide provides general considerations for the proper use of X-ray fluorescence (XRF) spectroscopy in the analysis of pigments and extenders as per ASTM D5381-93. XRF is commonly employed to determine elements present in inorganic pigments and extenders, often in…

📐 Scope and Overview of D5382-02 The ASTM D5382 −02 (Reapproved 2017) Standard Guide to Evaluation of Optical Properties of Powder Coatings serves as a roadmap for selecting the appropriate test methods for powder coatings. Optical properties are defined within…

📐 Scope and Applicability This test method, designated ASTM D5380-93 (Reapproved 2021), outlines the standard procedure for identifying crystalline pigments and extenders in paint through X-ray diffraction (XRD) analysis. It is designed to handle a wide variety of sample types,…

🧪 Product Types and Chemical Composition Trisodium phosphate is a white, uniform product suitable for washing, cleaning, and scouring processes where a moderately strong alkaline material is desired. It is available in three types specified by the purchaser based on…
