Overview

ASTM F2090-21 is the Standard Specification for Window Fall Prevention Devices With Emergency Escape (Egress) Release Mechanisms, developed by ASTM International. This standard establishes the minimum requirements for the installation, safety, performance, and labeling of devices designed to reduce the risk of injury or death from accidental falls through open windows, particularly by children aged five years and younger. Notably, it applies to devices used on all operable windows, including those designated for emergency escape (egress) and rescue (ingress). The specification is not intended to address the unique requirements mandated by the Americans with Disabilities Act (ADA).

Key Topics

• Scope and Applicability: Covers window fall prevention devices such as window opening control devices (WOCDs), window fall prevention screens, and window guards, applicable to new and existing window installations.
• Safety Requirements: Details the need to limit window openings to a size that restricts passage of a 4-inch (102 mm) diameter rigid sphere, commonly used as a proxy to prevent child falls.
• Performance Testing: Establishes rigorous static load, impact (pendulum), and release mechanism tests to simulate real-world use conditions and ensure product durability and reliability.
• Emergency Escape (Egress) Release: Devices must include easily operable release mechanisms allowing adults to open the window for emergency exit or rescue without the need for keys, tools, or special knowledge.
• Labeling and Instructions: Specifies mandatory safety warnings and installation instructions to support compliant use and proper maintenance.
• Manufacturer Compliance: Ensures full conformance, prohibiting partial adherence to the standard, and requires verification by window manufacturers if relying on third-party test reports.

Applications

ASTM F2090-21 provides essential guidance for:

• Window Manufacturers: Ensures that integrated or field-installed window safety devices meet robust safety and performance benchmarks.
• Residential and Commercial Property Owners: Helps property managers, landlords, and homeowners select compliant window fall prevention solutions, especially in multi-story dwellings and locations where children are present.
• Installers and Contractors: Offers clear criteria and installation instructions to achieve effective fall prevention while maintaining emergency egress, in line with local building and fire codes.
• Safety Inspectors: Assists code officials and building inspectors in verifying that installed devices meet the applicable safety and labeling requirements.
• Parents and Caregivers: Provides reassurance that properly installed and maintained devices can meaningfully reduce the risk of child falls from windows, while reinforcing the importance of supervision.

By following ASTM F2090-21, stakeholders can confidently enhance window safety without restricting the functionality of emergency escape routes.

INTRODUCTION
This consumer safety specification addresses window fall prevention devices that protect against
potential falls by children aged five years and under through open windows. Window fall prevention
devices currently available include window opening control devices (WOCDs), window fall
prevention screens, and some types of window guards. These devices use different strategies to
prevent children from falling through open windows. Window opening control devices (WOCDs)
restrict the size of the open area of the window so that it is too small for a young child to fall through.
They do this by allowing the window opening to be set at a predetermined position. Window fall
prevention screens and fall prevention window guards provide a barrier to prevent a child from falling
through an open window.
A special study by the U.S. Consumer Product Safety Commission (CPSC) indicates that young
children are at risk of death and serious injury from falls through open windows. Children aged five
and younger account for a higher percentage of window fall fatalities and injuries.
Windowfallpreventiondevicesusuallydifferinpurposeandapplicationfromsecurity/burglarbars.
The general purpose of a window fall prevention device is to prevent a child age five or younger from
falling through an open window. The general purpose of a security bar is to prevent unlawful entry
through a window. Generally, window fall prevention devices and security bars are two separate
devices. Security bars are generally permanently in place, cannot be released, and therefore would not
be considered a window fall prevention device under this standard.
The CPSC has advised caregivers to open windows less than 4 in. when children are present as one
means to prevent child falls through open windows. Window opening control devices (WOCDs)
provide a means that the window, when opened in an initial operation, will satisfy the CPSC
recommendationtoopenlessthan4in. The4-in.dimensionisdrawnfromrelatedbuildingcodesand
standards for openings in guardrail assemblies, and is universally accepted as the appropriate
dimension to prevent a child from passing through balcony or guard railing systems. An additional
operation is required to open the window further.The additional operation must be performed without
the use of keys, tools, or special knowledge. Security from forced entry is not within the scope of this
standard and is not the intended function of any of the devices referred to herein.
The intent of this update to this standard is to add new subsections 1.4 and 1.5 to the Scope section
for window manufacturers who rely on supplier test reports and to clarify that all the applicable
requirements of the standard must be met to claim conformance to this standard.Another update is to

Standard Specification for
Window Fall Prevention Devices With Emergency Escape
(Egress) Release Mechanisms
This standard is issued under the fixed designation F2090; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This consumer safety specification addresses window fall prevention devices that protect against
potential falls by children aged five years and under through open windows. Window fall prevention
devices currently available include window opening control devices (WOCDs), window fall
prevention screens, and some types of window guards. These devices use different strategies to
prevent children from falling through open windows. Window opening control devices (WOCDs)
restrict the size of the open area of the window so that it is too small for a young child to fall through.
They do this by allowing the window opening to be set at a predetermined position. Window fall
prevention screens and fall prevention window guards provide a barrier to prevent a child from falling
through an open window.
A special study by the U.S. Consumer Product Safety Commission (CPSC) indicates that young
children are at risk of death and serious injury from falls through open windows. Children aged five
and younger account for a higher percentage of window fall fatalities and injuries.
Window fall prevention devices usually differ in purpose and application from security/burglar bars.
The general purpose of a window fall prevention device is to prevent a child age five or younger from
falling through an open window. The general purpose of a security bar is to prevent unlawful entry
through a window. Generally, window fall prevention devices and security bars are two separate
devices. However, a security bar could be used as a Security bars are generally permanently in place,
cannot be released, and therefore would not be considered a window fall prevention device if it meets
the requirements of this specification. under this standard.
The CPSC has advised caregivers to open windows less than 4 in. when children are present as one
means to prevent child falls through open windows. Window opening control devices (WOCDs)
provide a means that the window, when opened in an initial operation, will satisfy the CPSC
recommendation to open less than 4 in. The 4-in. dimension is drawn from related building codes and
standards for openings in guardrail assemblies, and is universally accepted as the appropriate
dimension to prevent a child from passing through balcony or guard railing systems. An additional
operation is required to open the window further. The additional operation must be performed without
the use of keys, tools, or special knowledge. Security from forced entry is not within the scope of this
standard and is not the intended function of any of the devices referred to herein.
This specification is under the jurisdiction of ASTM Committee F15 on Consumer Products and is the direct responsibility of Subcommittee F15.38 on Window Fall
Prevention.

The intent of this update to this standard is to add new subsections 1.4 and 1.5the standard to the
Scope section for window manufacturers who rely on supplier test reports and to clarify that all the
applicable requirements of the standard must be met to claim conformance to this standard. Another
update is to improve the clarity of performancein 9.3.3 and labeling requirements and to reorganize
the sections such that the general requirements, performance tests, safety information, labeling
requirements, and installation instructions are separated byregarding the visibility of operating
mechanisms and correct a typo in 12.2 device type.replacing “hand tag” with “hang tag.”
1. Scope
1.1 This specification establishes requirements for devices intended to address the risk of injury and death associated with
accidental falls through open windows by children five years old and younger.
1.2 This specification is not intended to meet the unique requirements of Americans With Disabilities Act (ADA).
1.3 This specification applies to window fall prevention devices, including window opening control devices (WOCDs), window
fall prevention screens, and fall prevention window guards, that are to be used on operable windows, including those that are
designated for emergency escape (egress) and rescue (ingress).
NOTE 1—A separate safety specification, Safety Specification F2006, covers window fall prevention devices for non-emergency escape (egress) and rescue
(ingress) windows in installations more than 75 ft (23 m) above ground level in multiple family dwelling buildings since windows at these heights are
beyond the reach of rescue ladders currently in use.
1.4 Window manufacturers who rely on a test report from the supplier of the window fall prevention device shall verify that the
installation of the window fall prevention device (either installed by the window manufacturer prior to shipping of the window or
provided by the window manufacturer as a field installed kit) on their specific window product operator type complies with this
standard.
1.5 Partial compliance to this standard is not permitted. In order to claim compliance to this standard, all of the applicable
requirements in the standard must be met.
1.6 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.
1.7 This standard does not purport to address all 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.
1.8 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. Performance Tests
5.1 Preparing Specimen for Testing:
5.1.1 Window fall prevention guards shall be extended to the maximum width and height as specified by the manufacturer.
Extended fall prevention window guards and window fall prevention screens shall be mounted in a test frame or holder assembly
using installation techniques that are representative of the same mounting devices and techniques as recommended in the
manufacturer’s installation instructions. All testing shall be done with the fall prevention window guard or window fall prevention
screen device placed so that its inside (exposed) surfaces are subjected to the applied forces under 5.2 and 5.3.3.
5.1.2 The test supports shall be located in such a manner that they are contacting only the test frame and not providing any support
directly to the installed window fall prevention device.
5.1.3 Use the same window fall prevention device specimen for all performance tests (5.2 – 5.4). Test following the order indicated
by the performance test number sequencing.
5.2 Static Load (Hang) Test:
F2090 − 21
5.2.1 A load distribution device capable of exerting a 60 lb (267 N) force shall be used.
5.2.2 This test shall be performed for each different type of component in the window fall prevention device (vertical bars,
horizontal bars, webbing, or other graspable components, etc.).
5.2.3 With the window fall prevention device installed as specified in 5.1.1, suspend the load distribution device from each of the
individual component part members of the window fall prevention device (for example, hang the weight from a horizontal bar
component or from a member or opening of webbing, or other graspable component) in a manner that simulates the anticipated
load representative of a child hanging from any individual part of the window fall prevention device.
5.2.4 Apply a vertical force of 60 lb on the component at any representative point within or on the device. Reasoning statement:
To simulate the weight of a five year old child hanging from any component/part of the device.
5.2.5 Once the test weight is removed, the tested specimen is inspected to determine that the window fall prevention device shall
prohibit the free passage of a 4.0 in. (102 mm) diameter rigid sphere through or around it anywhere in the window opening (as
required by applicable codes for that jurisdiction).
5.2.6 The latching or locking device of release mechanism shall remain engaged and operative after testing.
5.3 Pendulum Test:
5.3.1 Rationale—This test is based on subjecting the window fall prevention screen or fall prevention window guard device to 100
ft-lb (136 J) of energy. This is the energy that would be generated by a 50-lb (22.7-kg) child (95th percentile 5-year-old) falling
directly onto the window fall prevention device from a height of 2 ft or running directly into the window fall prevention device
at a speed of 11.4 ft/s (3.48 m/s) (approximately 50th percentile 6-year-old sprint speed; 6 years is the youngest age for which data
are available).
NOTE 3—100 ft-lb is a reasonably stringent criterion. If, while bouncing on a bed for instance, the child fell against the window fall prevention device,
it is not likely that all of the energy from such a fall would be directed straight into the window fall prevention device, as it is in the testing situation.
In addition, the window fall prevention device is not intended to protect against an intentional all-out effort on the part of the child to run through the
window fall prevention device.
5.3.2 Test Objective—The test determines the fall prevention device’s resistance to allowing an opening to develop that would
permit a child to pass through after being impacted. The fall prevention device must not have an opening larger than the maximum
space as prescribed by 4.1. If such a space is found after the test, this will constitute failure of the device.
5.3.3 Test Procedure:
5.3.3.1 The fall prevention device is mounted into the test fixture utilizing the manufacturer’s written installation instructions.
5.3.3.2 The impactor (100 lb) (45.3 kg), such as in Figures 2 and 3 from ANSI Z97.1 (see Appendix X1), is prepared and mounted
to the test fixture cable so that when at rest it is no farther than 2 in. (50 mm) away from the horizontal and vertical center of the
window fall prevention device.
5.3.3.3 The impactor is pulled away from the specimen until the bottom of the impactor rises to the vertical distance of 12 in. 12 in.
(300 mm) above the at rest position.
5.3.3.4 When all motion has stopped, the impactor is released and allowed to impact once into the test specimen.
5.3.3.5 Once the impact is completed and the test weight is removed, the tested specimen shall prohibit the free passage of a 4.0-in.
(102-mm) diameter rigid sphere through or around it anywhere in the window opening (as required by applicable codes for that
jurisdiction).

mechanism of the window fall prevention device in accordance with manufacturer’s instructions.
5.4.1.1 Neither of the two distinct actions necessary to activate the release mechanism shall require a force greater than 15 lbf (66
N).
5.4.2 The window fall prevention device shall open promptly after the release mechanism has been activated.
5.4.3 Re-secure window fall prevention device into a closed position.
5.4.4 Perform this procedure for a total of five times with zero failures within a 2-min period. The release mechanism shall not
fail to operate.
