GSO ASTM E2397/E2397M:2024 Scope
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, Geo composite 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.
