A standard on geothermal testing methods is necessary because of the rapidly growing market in Europe of heat exchangers installation. Geothermal heat exchangers are used for heating and cooling and may be used in warmer and cooler areas throughout Europe. The use of...
This International Standard specifies requirements for the Geothermal Response Test (GRT). This test comprises the in situ determination of the thermal conductivity in saturated and unsaturated soil and rock in a heat exchanger installed in a borehole. For this test, liquid...
5.1 Deposits on heat transfer surfaces reduce efficiency of the heat exchanger affected. A method for easily determining the corrosion and fouling tendency of a particular water under heat transfer conditions will allow the evaluation of changes in the various system...

This Standard applies to fans and ventilation equipment that are a) cord-connected, rated at not more than 250 V; b) permanently connected to supply circuits of 600 V and less, single-phase or three-phase; and c) used in accordance with CSA C22.1, Canadian Electrical Code, Part I. - fans for use in...
This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric storage water heaters for household and similar purposes and intended for heating water below boiling temperature, their rated voltage being not more than 250 V for single-phase...
1.1 These practices cover the sampling of water-formed deposits for chemical, physical, biological, or radiological analysis. The practices cover both field and laboratory sampling. It also defines the various types of deposits. The following practices are included: Sections Practice A-Sampling...
5.1 Silicon (Si), a metalloid, is the second most abundant element in the earth's crust. Various forms of silica (silicon dioxide SiO2) are found in quartz, sand, and rocks. The degradation of these rocks results in silica found in natural waters. Silica in natural waters can be found as ionic...
This document gives guidance for system designers, installers, commissioners and maintenance teams on the incorporation of protective measures for air distribution systems including dual purpose systems for smoke and heat exhaust systems within buildings, to prevent the initiation and the...
