1.1 This specification covers the requirements for the compound and physical characteristics of heterogeneous polyurethane sheet flooring that is printed or otherwise decorated to achieve a pattern or visual and protected by a clear wear layer.1.2 This specification covers heterogeneous polyurethane sheet flooring that shall be composed of binder, fillers, and pigments. The binder shall consist of one or more resins of polyurethane, polyurethane copolymers or other suitable or any desirable combination. Other suitable polymeric resins may be incorporated as part of the binder, provided the polyurethane portion of the binder is greater than 60 % in the base layer.1.3 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.1.4 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.1.5 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.

The yield stress is a measure of the forces required to initiate and maintain flow from a storage vessel. If all the factors are constant, the propellant with the lower yield stress can be removed more completely from the vessel.1.1 This test method covers determination of the yield stress of heterogeneous propellants, both of the gel and emulsion types, containing from 0 to 70 % solid additives.1.2 The values stated in SI units are to be regarded as the standard. In cases where materials, products, or equipment are available in inch-pound units only, SI units are omitted.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 and health practices and determine the applicability of regulatory limitations prior to use.

4.1 This guide is suitable for sampling heterogeneous wastes.4.2 The focus of this guidance is on wastes; however, the approach described in this guide may be applicable to non-waste populations as well.4.3 Sections 5 – 10 describe a guide for the sampling of heterogeneous waste according to project objectives. Appendix X1 describes an application of the guide to heterogeneous wastes. The user is strongly advised to read Annex A1 prior to reading and employing Sections 5 – 10 of this guide.4.4 Annex A1 contains an introductory discussion of heterogeneity, stratification, and the relationship of samples and populations.4.5 This guide is intended for those who manage, design, or implement sampling and analytical plans for the characterization of heterogeneous wastes.1.1 This guide is a practical, nonmathematical discussion for heterogeneous waste sampling strategies. This guide is consistent with the particulate material sampling theory as well as inferential statistics, and may serve as an introduction to the statistical treatment of sampling issues.1.2 This guide does not provide comprehensive sampling procedures, nor does it serve as a guide to any specification. It is the responsibility of the user to ensure appropriate procedures are used.1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.1.4 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.1.5 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.
