Standard Specification for Residential Basketball Systems
ABSTRACT
This specification covers the performance and safety requirements intended to reduce the potential hazards associated with the manufacture, assembly, maintenance, and use of complete residential basketball systems. This specification is not intended to address the following: equipment intended to be used in places of public assembly (schools, parks, public and private recreational facilities, and the likes); individual components, such as rim, backboard, pole, portable base system, net, or other components not sold as a complete residential basketball system as defined here; any residential basketball system that is mounted to any structure or surface (roof mounting, wall mounting, or any locally or self-manufactured components) other than that which is purchased as part of a complete residential basketball system; any basketball equipment that does not use a full size rim, 18-in. (45.72-cm) diameter, or is designed for operational heights of less then 6 ft 6 in. (1.98 m) from the playing surface to the bottom of the backboard; and accessories and add-ons.
SCOPE
1.1 This specification covers the manufacture, assembly, recommended maintenance and use of complete residential basketball systems.
1.2 This specification is intended to reduce the potential hazards associated with the installation and use of residential basketball systems.
1.3 This specification is not intended to apply to the following:
1.3.1 Equipment intended to be used in places of public assembly, such as, but not limited to, schools, parks, public and private recreational facilities.
1.3.2 Individual components, such as rim, backboard, pole, portable base system, net, or other component when that component is not sold as a complete residential basketball system as defined in this specification.
1.3.3 Any residential basketball system that is mounted to any structure or surface other than that which is purchased as part of a complete residential basketball system. Examples include, but are not limited to, roof mounting, wall mounting, or any locally or self-manufactured components.
1.3.4 Any basketball equipment that does not use a full size rim, 18-in. (45.72-cm) diameter, or is designed for operational heights of less then 6 ft 6 in. (1.98 m) from the playing surface to the bottom of the backboard.
1.3.5 Accessories and add-ons.
1.4 This specification shall apply only to products manufactured after six months from the date this specification is published.
1.5 This specification does not cover product performance or quality, except as related to safety.
1.6 The tests are intended to uncover hazards, rather than to demonstrate the reliability of the system. The fact that a mechanism or material of a system fails during testing only is relevant if the failure creates a potential hazard.
1.7 The rationale for provisions in this specification are given in Appendix X1 and Appendix X2.
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.

Available from British Standards Institute (BSI), 389 Chiswick High Rd., London W4 4AL, U.K.
F1882 − 06 (2014)
FIG. 1 Normal Access Area
5.3 Edges, Points, and Surfaces—Following assembly of the system, in accordance with the instructions to be provided to the
consumer, there shall be no exposed sharp edges, points, or surfaces on any portion of the residential basketball equipment
according to CPSC 16 CFR 1500.48 and 1500.49.
5.4 There shall be no pinch, crush, or shear points as defined in 3.1.13.

5.7 Rims:
F1882 − 06 (2014)
FIG. 2 Portable Base Horizontal and Vertical Testing
5.7.1 Rims—Each rim shall be attached to a support structure in such a way that ensures the rim and all structural components
stay attached should the backboard break.
5.7.2 Backboards Made of Glass—All glass backboards shall be made of fully tempered glass. As specified in Specification
C1048, “Fully tempered glass is approximately four times as strong as annealed glass of the same thickness and configuration.
When broken, by impact, fully tempered glass fractures into relatively small pieces meeting safety glazing requirements thereby
greatly reducing the likelihood of serious cutting or piercing injuries in comparison with ordinary annealed glass. Fully tempered
glass is intended for used in applications where its strength or safety characteristics may be required.” The very nature of basketball
makes it obvious that the increased strength and safety characteristics of fully tempered glass should be required in any glass
backboard application.
6. Stability/Structural Integrity
6.1 Portable Base System Testing (To Be Performed by the Manufacturer)—The test should be performed to determine the
ability of the portable base system to withstand anticipated forces which act to tip, slide, or cause permanent deformation, or a
combination thereof, to the system. Complete assembly/installation according to manufacturer’s recommendations. The force for
all tests shall be applied gradually within a period of 1 min and maintained for a period of 5 min. All tests are to be performed
at a room temperature of 68 6 5°F (22 6 15°C). This test must be performed with rim at 10-ft (3.05-m) regulation height and
through its entire recommended adjustment range. The system must be tested without additional supplemental restraint systems.
After conducting the tests, there shall be no visible cracks, permanent deformation, breakage, or deterioration of any component
that may adversely affect the structural integrity or safety of the equipment.
6.1.1 Horizontal Testing (Fig. 2)—To simulate a 40-mph (64.4-kph) wind force, calculate the square footage of the backboard
and refer to Fig. 3 to determine the horizontal load required to replicate the wind force. For Test No. 1, apply this horizontal load
as shown in Fig. 2. If the rim height at the point of load application drops more than 6 in. (15.24 cm), stop the test and reposition
the pulley. Proceed to Test No. 2. For Test No. 2, if required, with pulley realigned 6 in. (15.2 cm) lower, reapply horizontal test
load and check if rim height drops more than 6 in. (15.24 cm). If so, repeat in 6-in. (15.14-cm) pulley height reduction segments.
The test must be performed in both forward and rearward directions, and the system must not tip over beyond the balance point,
in accordance with Fig. 4.
6.1.2 Horizontal Rim Weight (Fig. 5)—Determine the weight of the system (at the rim) while in a level horizontal position (80
lb (36.39 kg) max.
6.1.3 Vertical Minimum Load (Fig. 2)—This load is 101.25 lb (45.93 kg), and it must be applied vertically from the tip of the
rim. With the required load, system must not tip over past its balance point in accordance with Fig. 4.
6.1.4 Balance Point of System Testing (Fig. 4)—Pull system forward to the point of balance where it will not fall forward or
backward. The maximum distance between the tip of rim and the ground should be less than 5 ft 6 in. (1.68 m). When the system
is released backwards above the natural balance point, it must return system to the normal upright position.
6.1.5 Horizontal Side Testing (Fig. 6)—With a 25-lb (11.34-kg) load, the portable system must not tip over sideways to such
a point where the rim/backboard touches the ground.
6.1.6 Portability Test on an Incline (Fig. 7)—When following manufacturer’s recommendations for moving the portable system,
the system must remain in its transport (movable) position when placed on a 5° slope in any direction.
6.1.7 When following the manufacturer’s recommendations for moving the portable system, the system must be capable of
being moved a distance of 50 ft (15.24 m).
6.2 Ground Base System Testing (to be performed by the manufacturer)—The test should be performed to determine the ability
of the ground base system to withstand anticipated forces which act to tip, slide, or cause permanent deformation, or a combination
thereof, to the system. Complete assembly/installation according to manufacturer’s recommendations. The force for all tests shall
be applied gradually within a period of 1 min and maintained for a period of 5 min. This test must be performed with rim at 10-ft
