Significance and Use 4.1 Every elevated play structure is required to have a protective surface installed and poured-in-place surfaces are one of the many choices. These surfaces are highly technical in structure, component selection, percentages of components and installation procedures. This guide is intended to assist the playground owner/operator, specification writer, designer, and so forth in determining the properties that can be considered with regard to the poured-in-place surface and set out considerations that the user of this guide should make to ensure a successful installation. This document is a guide and should not be used directly as a performance specification for poured-in-place surfacing.Scope 1.1 This guide covers information with regard to the design, manufacture, installation, and maintenance of poured-in-place playground surfaces. Note 1: This document is a guide and not intended to be used as a specification; it should be used for educational purposes. 1.2 This guide outlines the issues of compliance with existing standards, durability, and functional longevity. 1.3 This guide reviews issues such as edge treatment, abutting surfaces, and combinations with other surfaces designed for circulation or protective surfaces. 1.4 This guide presents maintenance considerations and general procedures that should be followed by the owner/operator. 1.5 This guide outlines aging considerations such as loss of impact absorption, cracking, shrinkage, heaving, and how to prevent, accommodate, or rectify those issues. 1.6 This guide presents warranty considerations. 1.7 This guide does not imply that an injury cannot be incurred when the surface system is compliant with the standards referred to in this guide. 1.8 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. 1.9 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. 1.10 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.
