This publication provides comprehensive guidance for systematic development and implementation of a plan for commissioning building HVAC and Plumbing systems. The third edition represents a departure from past editions and is divided into three distinct parts: Standards, Process and...
5.1 Traditionally, HFTs have been incorporated into laboratory testing devices, such as the heat flow meter apparatus (Test Method C518), that employ controlled temperatures and heat flow paths to effect a thermal measurement. The application of heat flux transducers and temperature...
5.1 The solar reflectance of a building envelope surface affects surface temperature and near-surface ambient air temperature. Surfaces with low solar reflectance absorb a high fraction of the incoming solar energy. Sunlight absorbed by a roof or by other building...
5.1 Effects of Air Change-Air change often accounts for a significant portion of the heating or air-conditioning load of a building. It also affects the moisture and contaminant balances in the building. Moisture-laden air passing through the building envelope can permit...
1.1 This specification covers cold expansion fittings and cross-linked (PEX) reinforcing rings for use with cross-linked polyethylene (PEX) plastic tubing in nominal tubing sizes of 3/8 , 1/2 , 5/8 , 3/4 , 1, 11/4 , 11/2 , 2, 21/2 , and 3 in. that meet the requirements of Specification F876 or...
5.1 Fenestration products, when exposed to differential temperatures (constant higher or lower temperatures on the exterior and room temperature on the interior), or temperature cycling (relatively constant room temperature on the interior and repeated cycling of...
1.1 This guide covers the general effects of temperature from the aerosol foam sealant (either polyurethane or latex types) under the use temperatures. 1.2 The guide is intended to estimate the observed product dispensing characteristics and foam quality of aerosol foam dispensed or...
4.1 The thermal resistance of a ceiling system is used to characterize its steady-state thermal performance. 4.2 The thermal resistance of insulation is related to the density and thickness of the insulation. Test data on thermal resistance are obtained at a thickness and density representative of...
1.1 This specification covers the general requirements for faced thermal insulation boards composed of rigid cellular polyisocyanurate surfaced with other materials. The insulation boards are intended for use at temperatures between?-40 and 200°F (-40 and 93°C). This specification does not...
6.1 SPF insulation is applied and formed onsite, which creates unique challenges for measuring product emissions. This test method provides a way to measure post-application chemical emissions from SPF insulation. 6.2 This test method can be used to identify compounds that emit from SPF insulation...
