Examines the formation of scale, usually calcium carbonate, in once-through hot water storage cylinders, and makes design recommendations to minimise scale deposition and its effects.
5.1 This test method is intended for use in the laboratory or field in evaluating distillate fuel cleanliness. 5.2 A change in filtration performance after storage, pretreatment, or commingling can be indicative of changes in fuel condition. 5.3 Relative filterability of fuels may vary...
5.1 Proton exchange membranes (PEM) used in fuel cells are susceptible to contamination from a number of species that can be found in hydrogen. It is critical that these contaminants be measured and verified to be present at or below the amounts stated in SAE J2719 and ISO 14687 to ensure both fuel...
1.1 This test method covers two procedures for estimating the presence of suspended free water and solid particulate contamination in distillate fuels having distillation end points below 400?°C and an ASTM color of 5 or less. 1.1.1 Both procedures can be used as field tests at...
This document specifies a method for the energy assessment of domestic/sanitary hot water storage tanks of up to 2 000 l. Whilst this document does not cover water heaters intended primarily for direct heating, it does allow the provision of electric heating elements for...
5.1 The sample preparation procedure for comminution impacts other downstream processes such as extraction and sonication, which ultimately affects the total analytical error (TAE) and measurement uncertainty. 5.2 Factors that may influence the sample preparation process include the prevention of...
1.1 This specification covers the requirements for Halon 1301 as a fire-fighting medium. 1.2 This specification does not address the fire-fighting equipment or hardware that employs Halon 1301 or the conditions of employing such equipment (for example, handhelds, fixed installations, etc.). 1.3...
5.1 General: 5.1.1 Sediment provides habitat for many aquatic organisms and is a major repository for many of the more persistent chemicals that are introduced into surface waters. In the aquatic environment, most anthropogenic chemicals and waste materials including toxic organic and inorganic...
1.1 This specification covers requirements for HFC-227ea as a fire-fighting medium. 1.2 This specification does not address the fire-fighting equipment or hardware that employs HFC-227ea or the conditions of employing such equipment (for example, handhelds, fixed installations, etc.). 1.3 This...
1.1 This guide offers guidance for the characterization and use of hygrothermal models for moisture control design of building envelopes. In this context, "hygrothermal models" refers to the application of a mathematical model to the solution of a specific heat and moisture flow performance issue...
This standard describes the design, fabrication, installation, inspection, and testing of bolted aboveground thermosetting fiberglass-reinforce
This specification covers the standard requirements for the application of full thickness Portland cement-based plaster for exterior (stucco) and interior work. It also sets forth tables for proportioning of various plaster mixes and plaster thickness. The materials used shall consist of the...
5.1 This guide describes the techniques used to test for watertightness of waterproofing installations on horizontal services having a slope not greater than 20 mm/m (2 % slope) (1/4 in./ft). See also ACI 515. 5.2 The structural capacity of the substrate to which the waterproofing system is to be...
Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. This standard shall be used to determine the adhesion of organic coatings on...
5.1 This test method determines the amount of water absorbed by a backing material. Water absorption by the backing may affect sealant performance. 5.2 This test method is also useful when designating proper storage of back up material and in determining appropriate precautions...
5.1 This guide will help manufacturers and users of AM powder feedstocks to identify suitable methods for measuring moisture in the feedstocks. 5.2 This guide will aid control of powder quality and allow powder producers and users of AM machines to assess moisture content of virgin and reused...
