Ultra-Accelerated EMMA Testing

Product catalog summary

Introduction to Ultra-Accelerated EMMA®

The Ultra-Accelerated EMMA (UA-EMMA) is a cutting-edge outdoor testing device developed by Atlas. It simulates approximately 10-12 years of natural radiation exposure in just one year, using a patented 'cool mirror' technology that reflects UV and near-visible wavelengths while reducing longer wavelength visible and IR reflectance.

Advantages of UA-EMMA

Accelerated testing for various materials under ultra-high UV irradiance.
Maintains fidelity to the natural solar UV spectrum.
Ensures specimens are exposed at acceptable temperatures.

Ideal Materials for Testing

Materials requiring long service life.
Transparent and glazed materials.
Temperature-sensitive materials like PVC.
Coatings on metal panels.
Materials performing well in EMMA or EMMAQUA exposure tests.

Comparison and Performance Data

Graphs and data compare the black panel temperature performance and UV radiant exposure between UA-EMMA and standard EMMA, showing UA-EMMA's efficiency in accelerated testing.

Historical Development

1958: Introduction of the first EMMAQUA® device.
1969: Redesign with steel framework and efficient spray system.
1986: Introduction of EMMAQUA+® with advanced features.
1999: Launch of MQ3K with state-of-the-art technology.
2004: Introduction of temperature-controlled EMMAQUA suites.

Applications

Adhesives, agricultural films, automotive exteriors, building materials, elastomers, glass, packaging, paints, coatings, plastics, roofing, and sealants.

Weathering Standards

EMMAQUA exposure standards include ISO 877-3, ASTM standards for various materials, and SAE standards for automotive applications.

THE BENEFITS OF ULTRA-ACCELERATED TESTING What is the Ultra-Accelerated EMMA ? ® The Ultra-Accelerated EMMA (UA-EMMA) is Atlas’ latest advancement in natural exposure testing. This new outdoor testing device delivers approximately 10-12 years of equivalent radiation exposure as would be received in a standard outdoor testing rack in South Florida in a single year. The system achieves this accelerated exposure through a patented “cool mirror” technology that has very high reflectance in the UV and near visible wavelength ranges while attenuating reflectance in the longer wavelength visible and...
