5.1 Post dispensing volumetric expansion factor F indicates the ratio of the fully cured foam sealant volume and the initially dispensed foam sealant volume. For example, if the expansion factor F were 2, the fully cured foam would double its initial volume; therefore, one should fill 50 % of the cavity uniformly to anticipate the full coverage upon curing.5.2 Post dispensing volumetric expansion factor F does not predict the performance capability of the foam sealants of the suitability for the intended applications.5.3 This test method is intended to lend guidance in product selection as related to the post dispensing expansion characteristics of the aerosol foam sealants.5.4 This test method recognizes that the results are reflective of controlled laboratory conditions. Post dispensing expansion in field applications may vary according to temperature, humidity, and surfaces that the aerosol foam sealants are in contact with.1.1 This test method measures the volumetric expansion of aerosol foam sealants after dispensing.1.2 This test method provides a means for estimating the quantity of initial material required to dispense in order to fill a cavity.1.3 Aerosol foam sealants are used for a variety of applications intended to reduce airflow through the building envelope.1.4 This test method applies to two types of single component aerosol foam sealants: polyurethane and latex.1.5 There are no other known standard test methods to measure aerosol foam sealants post dispensing expansion.1.6 Values are reported in SI units only. Certain apparatus and supply items are referenced in inch-pound units for purchasing purposes.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.

This specification covers the material, dimensions, and construction of 5 and 10-gal (20 and 40-L) tanks purchased to store and dispense lubricating oils. The tanks are industrial safety cans mounted on a T-bar bracket, complete with drip tray. Internal air pressure test shall be performed on the tank to meet the requirements prescribed. There should be no visible seam leakage when subjected to underwater or soap bubble test.1.1 This specification covers the material, dimensions, and construction of 5 and 10-gal (20 and 40-L) tanks purchased to store and dispense lubricating oils. The tanks are industrial safety cans mounted on a T-bar bracket, complete with drip tray.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 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.1.4 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 This guide is not intended to measure the precise temperature range for dispensing and curing product under all the possible substrate and environmental factors but to provide a basis for benchmarking a foam sealant product under specific laboratory conditions.5.2 The product user is encouraged to evaluate each application and determine suitability for actual use.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 cured, or both, at specific temperatures and standard conditions.1.3 Such foam sealants are primarily intended to reduce air movement in and out of building enclosures.1.4 Currently two main foam sealant types are applicable to this standard: single component polyurethane and latex.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 There are no other known test methods specific for measuring the product temperature range for aerosol foam sealant.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.
