4.1 Hydraulic cleaning methods include equipment that uses water and water velocity to clean the invert and walls of Thermoplastic Sewer Pipe. 4.2 The practice of high-velocity sewer cleaning is best described as a hydraulic cleaning method that uses water pressure to remove...
5.1 Compression testing of soil-lime specimens is performed to determine unconfined compressive strength of the cured soil-lime-water mixture to determine the suitability of the mixture for uses such as in pavement bases and subbases, stabilized subgrades, and structural fills. 5.2...
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...
This document provides guidelines for the planning, design and construction of a cylindrical tank constructed on the ground with prestressed concrete (PC) for use with potable water tank. This document is applicable to PC tanks for potable water with a...
This Standard specifies the methods for determining the uniform energy factor for electric storage tank water heaters and heat pump water heaters. This Standard a) establishes minimum energy efficiency levels for electric storage tank water heaters and heat pump...
This document specifies methods for testing the sound power level of air/water, brine/water, water/water and direct exchange/water heat pump water heaters and heat pump combination heaters with electrically driven compressors and connected to or including a...
This European Standard specifies requirements for design, calculation and installation of factory made thermal insulated bonded single and twin pipe systems for directly buried networks for continuous operation with treated hot water at various temperatures up to 120 ºC and...

5.1 This is not a routine test. The values recorded are applicable only to the tank being tested and at the time of testing. This test is intended only to demonstrate the sealing effectiveness of the installed system. Structural design of the tank is defined or demonstrated...
5.1 Concepts: 5.1.1 This guide summarizes the equipment, field procedures and interpretation methods used for the characterization of subsurface materials and geological structure as based on their properties to conduct, enhance or obstruct the flow of electrical currents as induced in the ground...
Description The trap seal primers are of four (4) types: a) Those that are installed on waste line tail pieces from fixtures, such as lavatories, sinks and similar fixtures where grease is not normally generated; b) Those that are used in conjunction with ballcock assemblies; c) Those that receive...
This European Standard specifies the terms, definitions, test conditions, test methods and requirements for rating the performance of air conditioners and liquid chilling packages, with electrically driven compressors and with evaporatively cooled condenser when used for space cooling. The...
