Beyond Components: Why The Industry Is Moving Toward Tested Opening Assemblies

For decades, the commercial openings industry has evaluated products largely through the lens of individual components. Doors, frames, hardware, glazing, and locking systems were tested and certified independently, allowing architects, distributors, and building owners to assemble solutions from multiple sources while maintaining confidence in code compliance and performance.

That approach has served the industry well.

However, as performance requirements become increasingly complex—and as security concerns continue to evolve—the industry is recognizing an important reality:

A building opening does not perform as a collection of individual components. It performs as a system.

This shift in thinking is driving growing interest in assembly-level testing and certification, particularly in applications where life safety, security, and risk mitigation are critical. From fire protection and hurricane resistance to school security and forced-entry protection, performance expectations are increasingly centered on how complete opening assemblies function under real-world conditions.

The evolution toward certified opening assemblies is not a rejection of component testing. Rather, it represents the next step in the industry's ongoing effort to deliver greater confidence, consistency, and accountability.

Confirm Hardware Requirements Before Selecting Door Prep

Door prep must match the intended hardware exactly. To ensure accuracy, hardware selections should be based on the project’s approved documentation—not solely on available options in Forte’s DOORBUILDER^® configurator.

Hardware manufacturers regularly update product offerings, templates, and machining requirements. Changes can result from new products, acquisitions, revised templates, or project-specific requirements. In some cases, the latest template information may only be available directly from the manufacturer.

Before submitting an order, please compare the selected hardware and door prep with the approved documents, including:

Current manufacturer templates
Template number and revision or publication date
Hardware schedule
Machining sheet
Project-specific instructions or details

Confirming the template number and date is especially important. A hardware model may appear familiar, but a revised template can require different machining.

Watch for Modified Hardware

Some hardware is identified as “modified” because it varies from a manufacturer’s standard offering. While the product may resemble a standard lock, exit device, or other item, even a small modification can change the required door preparation.

If a hardware description includes the word “modified,” please make sure the project documentation clearly identifies the required prep. Modified hardware should not be treated as a standard selection when the change affects machining.

Using DOORBUILDER^® Effectively

DOORBUILDER^® includes features designed to help users identify and select appropriate hardware, including:

Hardware search tools within hardware categories and at the order-header level
Available template dates, with the most current known template displayed first
Holder options filtered by the selected hinge or pivot type
Alerts for modified or non-standard hardware selections

These tools can support the selection process, but they do not replace review of the customer’s approved hardware documents.

The Evolution of Active Shooter Testing

As concerns surrounding school security intensified, the industry began developing more realistic methods for evaluating opening performance.

Earlier testing approaches often examined ballistic resistance, burglary resistance, or manual attack independently. While valuable, these methods did not fully represent the sequence of events associated with many active shooter scenarios.

The development of FTD-SA marked an important advancement by combining ballistic attack with subsequent forced-entry testing. Rather than focusing solely on whether glazing could stop a projectile, the methodology evaluated how the opening performed after sustaining damage.

This represented a significant shift toward systems-based evaluation.

For the first time, testing focused not only on individual components but also on the opening's ability to maintain integrity under a realistic sequence of attacks.

The industry's continued pursuit of consistency and broader adoption eventually led to ASTM F3561, which formalized many of these concepts through a consensus-based standard.

ASTM F3561 and the Shift Toward Assembly Performance

The introduction of ASTM F3561 represents more than the arrival of another testing method.

It reflects an industry-wide recognition that security performance must be evaluated at the assembly level.

Unlike proprietary testing programs, ASTM standards are developed through collaboration among manufacturers, architects, testing laboratories, security experts, code officials, and other stakeholders. This consensus process creates a common framework that can be broadly referenced across specifications, projects, and jurisdictions.

More importantly, ASTM F3561 evaluates the performance of complete opening assemblies under combined ballistic and forced-entry conditions.

This approach aligns with a growing industry understanding that openings succeed—or fail—as systems.

The standard provides a common language for discussing attack-resistant performance while helping architects and building owners compare solutions using consistent evaluation criteria.

Why Architects Are Increasingly Interested in Tested Assemblies

For architects and specifiers, assembly-level certification offers several practical advantages.

1. Greater Confidence in Performance

Design teams are increasingly responsible for validating that security-related design decisions align with owner expectations and project requirements.
Certified assemblies provide confidence that all components have been evaluated together rather than relying on assumptions about compatibility.

2. Simpler Specifications

Performance-based specifications are becoming more common throughout the industry..
When assemblies are tested and certified as complete systems, architects can focus on desired outcomes rather than attempting to coordinate performance requirements across multiple independent components.

3. Reduced Substitution Risk

Substitutions can introduce uncertainty when replacement products have not been evaluated within the same tested configuration.
Assembly certification helps preserve design intent by establishing a validated system rather than a collection of individually compliant products.

4. Better Defensibility

As accountability surrounding school security and life-safety decisions continues to grow, standardized testing provides a more objective foundation for specification decisions.
Rather than relying on marketing claims or interpretations of component-level testing, architects can reference documented system performance.

5. Reduced Compatibility Concerns

Tested assemblies help eliminate uncertainty about whether components have been evaluated together.
This can reduce project risk and simplify coordination among manufacturers, installers, and project stakeholders.

6. Fewer Field Problems

Many project challenges emerge when individually compliant components are combined in configurations that have never been tested together.
Assembly certification helps reduce these unknowns by validating performance before products reach the jobsite.

From Components to Systems

Consider two opening solutions designed for the same classroom application.

The first consists of individually tested components sourced from multiple manufacturers. Each component satisfies its own performance requirements, but the complete assembly has never been evaluated as a unified system.

The second consists of a tested and certified opening assembly in which the door, frame, hardware, glazing, and anchorage have been evaluated together under realistic attack conditions.

Both solutions may appear comparable on paper.

However, only one provides verified evidence of how the complete opening performs when subjected to real-world conditions.

That distinction is becoming increasingly important as security requirements become more sophisticated and accountability continues to increase.

The Future of Opening Performance

The commercial openings industry has followed this pattern before.

Fire-rated assemblies, impact-resistant systems, accessibility requirements, and energy-performance standards all evolved from voluntary best practices to broadly accepted industry expectations.

Security performance appears to be following a similar path.

As standards mature, specifications become more performance-based, and owners demand greater accountability, the focus will continue shifting toward validated opening assemblies rather than isolated component claims.

The industry's direction is becoming increasingly clear:

Openings will be evaluated as complete systems.
Performance claims will become more standardized and verifiable.
Assembly-level testing will play a larger role in specification decisions.
Certified assemblies will become increasingly important in high-performance applications.

Ultimately, the movement toward certified opening assemblies is about more than testing.

It is about providing architects, distributors, owners, and occupants with greater confidence that the opening will perform as intended when performance matters most.

In an industry increasingly focused on safety, resilience, and accountability, that evolution is both logical and necessary.
