4.1 This guide is intended to provide a standardized method and a set of basic instructions for performing stack testing on UN packaging designs using either guided or unguided top loads. This guide provides the suggested minimum information that should be documented when conducting stacking test and provides information for recommended equipment.4.2 All packaging design types other than bags must be subjected to a stacking test. Packagings subject to the stacking test must be capable of withstanding a superimposed top load of a specified minimum mass for a specified period of time without failure as these parameters are defined in the regulations. The test is not intended to determine the absolute top load capability of a packaging.NOTE 1: When quantification of box compression strength is desired for determining stacking strength or for design purposes use Test Method D642 and conditioning as recommended in 4.5.4.3 Design qualification testing procedures are intended, as explicitly stated in the HMR, to be the minimum performance capability levels for packaging manufactured to transport Hazardous Materials under conditions normally incident to transportation.4.4 The HMR tests are designed to be gross package capability evaluations that can be performed in a similar manner in all parts of the world, but under circumstances with some variance in test facility capabilities. This is an intentional feature of the test designs and protocols. The focus of HMR testing is not the determination of quantifiable, comparison data to allow for analytical evaluation.4.5 It is recommended that facilities performing the HMR tests consult the guidance on conditioning in the relevant ASTM documents for any particular packaging material as applicable. The following conditioning documents, Practices D4332 and D685, are commonly used.1.1 This guide is intended to provide a standardized method and a set of basic instructions for conducting stacking tests on United Nations (UN) non-bulk, intermediate bulk container (IBC), and Large Packagings. Using guided or unguided loads in accordance with the U.S. Department of Transportation Title 49 Code of Federal Regulations (CFR) and the UN Recommendations on the Transport of Dangerous Goods (“The Orange Book”). The combination or interchange of these regulations will be referred to as the Hazardous Material Regulations (HMR).1.2 The Dangerous Goods Regulations require performance tests to be conducted on packaging designs prior to being authorized for use. The regulations do not include standardized procedures to accomplish this which can result in differences between testing facilities. The purpose of this document is to provide guidance and to establish a set of common practices for conducting stack testing on packagings undergoing UN certification.1.3 The user of this guide must be trained in accordance with 49 CFR as required by 172.700 and should be familiar with other applicable hazardous materials regulations such as; International Civil Aviation Organization (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air, the International Maritime Dangerous Goods Code (IMDG Code), and carrier rules such as International Air Transport Association (IATA) Dangerous Goods Regulations.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 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 practice addresses performance characteristics for vegetative (green) roof systems with respect to the dead load and transient water load of the entire vegetative (green) roof system.5.2 Determining these performance characteristics of vegetative (green) roof systems provides information to facilitate the assessment of related engineering aspects of the facility. Such aspects may include structural design requirements, mechanical engineering and thermal design requirements, and fire and life safety requirements.5.3 Determining these performance characteristics of vegetative (green) roof systems provides information to facilitate assessment of the performance of one vegetative (green) roof system relative to another.1.1 This practice covers a standardized procedure for predicting the system weight of a vegetative (green) roof system.1.2 The practice addresses the loads associated with vegetative (green) roof systems. Components that are typically encountered in vegetative (green) roof systems include: membranes, non-absorptive plastic sheet components, metallic layers, fabrics, geocomposite drain layers, synthetic reinforcing layers, cover/recover boards, insulation materials, growth media, granular drainage media, and plant materials.1.3 This practice also addresses the weight of the vegetative (green) roof system under two conditions: (1) weight under drained conditions after new water additions by rainfall or irrigation have ceased (this includes the weight of retained water and captured water), and (2) weight when rainfall or irrigation is actively occurring and the drain layer is completely filled with water. The first condition is considered the dead load of the vegetative (green) roof system. The difference in weight between the first and second conditions, approximated by the weight of transient water in the drain layer, is considered a live load.1.4 This practice does not address point or line loads associated with architectural elements that are not essential components of a particular vegetative (green) roof system. These architectural elements may include pavement, walls, and masonry, and so forth.1.5 This practice does not address live loads associated with construction activities.1.6 This practice does not address loads associated with snow or wind.1.7 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.8 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 to determine the applicability of regulatory limitations prior to use.1.9 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.
