Testing is the process used to compare a product (in this case, an aluminum composite material [ACM] panel system) to an industry-established benchmark for a given set of performance criteria. In general terms, testing is used as a measure of quality and performance, and helps to determine if a product and/or system is suitable for a particular application.
Testing is a measure of quality, performance and suitability
Testing and Standardization
The availability of standardized testing provides an industry benchmark and performance requirements, ensuring that products and systems are tested against a specific set of criteria and conditions. This allows for an objective comparison to all similarly tested products within an industry.
From a manufacturer’s perspective, testing validates the overall performance and manages risk as a product and/or system is launched to the market. It can also help highlight competitive performance advantages that one product or system has over another.
From an end user’s perspective, testing can provide quality assurance, and verify the product and system’s performance to maintain customer satisfaction. It also helps to ensure users understand the variety of products and systems available, which ones are appropriate for their specific needs/requirements, and which will provide them with the best value.
ACM Performance Requirements
While there are many standards as established by American Architectural Manufacturer Association (AAMA) and ASTM International that ACM panels must meet, it is crucial to understand the importance of having the complete wall assembly tested. Having just one system component meet performance requirements does not necessarily mean the collection of materials used in the wall assembly will perform well together.
The most common ACM wall assembly tests include:
National Fire Protection Agency (NFPA) 285 Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components: NFPA 285 provides a standardized fire test procedure for evaluating the fire propagation characteristics of exterior, non-load bearing wall assemblies that incorporate and are constructed with combustible components. Passing this stringent test demonstrates the ability of an exterior ACM panel and specific components installed in the system to limit vertical and horizontal flame spread.
AAMA 508 Voluntary Test Method and Specification for Pressure Equalized Rain Screen Wall Cladding Systems: AAMA 508 provides a standardized test procedure for wall assemblies that have been sealed around the edges. The test evaluates air leakage, water penetration, structural performance and pressure equalization behavior.
AAMA 509 Voluntary Test and Classification Method for Drained and Back Vented Rain Screen Wall Cladding Systems: AAMA 509 provides a standardized test procedure for an open-joint wall assembly. The purpose is to quantify the volume of water within the wall assembly and the system’s ability to allow for ventilation and drying as measured by air flow. The test evaluates air flow volumes, water penetration and structural performance.
Making Sense of it All
Not every product or system is appropriate for every application. It’s important to research your options and be aware of the performance requirements and regional regulations that may limit the compliance of certain ACM panel systems under specific conditions.
External testing requirements provide a benchmark that can be used as a means for objective comparison of both quality and performance between ACM panel systems in today’s market. If it seems the testing results are the same or similar for several products, it’s worth considering additional factors to help make the final decision. For example, consider the longevity of the manufacturer and the level of support they’re able to provide.
Minimum order quantities and lead times are some other factors to consider. Most importantly, be sure to ask questions about the product, testing and technical information you’ve received. Dig deeper to make sure you’re really performing a true comparison to select the best ACM panel and system for your project.
