The collection of empirical data to determine building energy performance is an important but complex and costly activity. Careful development of energy monitoring projects can make a crucial difference in the value of project results relative to the expense.Increasing the widespread understanding of how energy is used and the types of services it provides in commercial, institutional, and related (light industrial, large multifamily, and mixed commercial/residential) buildings has proved to be difficult. This difficulty arises from the following variables: the complexity of buildings as energy systems; the diversity of sizes, uses, schedules, and types of buildings; the changes in uses of buildings; and the mixture of uses within individual buildings. These factors make building energy performance and energy (and dollar) savings from energy improvements difficult to categorize and compare.The audience for this guide is diverse, including energy suppliers such as utilities, building owners and managers, building occupants, designers, public and private research organizations, equipment manufacturers, and public regulators.The user of this guide must be familiar with the fundamental techniques of engineering project management and energy performance data collection, data management, and data analysis. See Refs (1-4)3 for a discussion of techniques related to the collection and analysis of energy performance data.1.1 This guide covers a methodological approach to developing protocols for collecting empirical building or facility energy performance data.1.2 The methodological approach covered in this guide is appropriate for commercial and institutional buildings or facilities, and with some adaptations, the approach can also be used for larger multifamily buildings or small industrial buildings or facilities.1.3 This guide does not specify a complete project or experimental design, the hardware or software needed for data collection and data management, or the data analysis techniques to be used.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 The test method results are suitable for use by manufacturers of colorants and bases for quality control purposes on manufactured product.5.2 The test method results are suitable for use by purchasers of colorants and bases for incoming quality control or the determination of money value of colorants and bases.1.1 This test method covers the determination of strength of colorant dispersions, colored and white bases, for architectural, marine, maintenance, commercial, and industrial coatings.1.2 This test method applies to colorant dispersions and colored and white bases regardless of the methods used to disperse these materials.1.3 The resultant test value is in terms of percent strength in which a material stronger than standard is implied by values larger than 100 % and weaker than standard is implied by values less than 100 %. The value of 100 % implies exact strength conformance to the test method.1.4 This test method is suitable for the determination of strength when tolerances are set about standards that are prepared either by weight concentration or volume concentration.1.5 The test result is empirically determined. The user determines and supplies the standard for strength of the product under test and the test result is relative to that supplied standard.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The maximum energy input rate test is used to confirm that the dishwasher is operating at the manufacturer's rated input prior to further testing. This test would also indicate any problems with the electric power supply, gas service pressure, or steam supply flow or pressure.5.2 The tank and booster temperature are verified and water consumption is adjusted to NSF specifications to ensure that
