Q-RACK outdoor exposure racks are the same aluminum racks that are used at Q-Lab Florida and Q-Lab Arizona to perform natural outdoor exposure tests. Now you can buy these professional quality racks to perform exposures at your own site.
The durable Q-RACK design has been proven over decades of harsh subtropical and desert exposures. The racks are versatile, dependable, and affordable, and come in kit form for easy assembly.
Q-RACK kits, accessories and non-standard mounting systems are available for different applications and testing requirements. They meet ISO, ASTM, SAE and other international standards for outdoor testing. The Q-RACK frame may be positioned at 0°, 5°, 45° or 90°.
Q-RACK Outdoor Exposure Racks
Q-RACK outdoor exposure rack kits are available in two types: direct exposure and under glass exposure. See LR-3001 – Q-RACK Brochure for photos and more detailed information.
In direct exposure racks, specimens are directly exposed to the environment. It is the most common method for testing coatings, inks, plastics, or finishes used outdoors. Most typical test specimens can be easily mounted on a Q-RACK direct exposure system. Our direct exposure rack kits meet the requirements of ISO 877-2 Method A, ASTM G7, ASTM D4141, or SAE J1976. Be sure to visit our Standards Page for other information about relevant standards for Q-RACK systems or our other products and services.
Under glass exposure racks are primarily used to test automotive interior materials. Specimens are exposed to sunlight behind special glass panels.

Q-RACK Direct Exposure Rack Kits
Q-RACK direct exposure rack systems feature two legs and an anodized aluminum main frame measuring 3.66 x 1.68 x 0.10m. Both welded frames and unassembled “knock-down” frames are available, depending on your shipping location. Panel base and flap assemblies hold panels in place and may be adjusted to fit various sizes of test specimens. Q-RACK direct exposure rack kits have one panel base and five panel flaps; additional panel assemblies may be ordered to hold more specimens.
Sturdy positioning arms are used to hold frames securely at the correct angle of exposure (see Accessories). Sold in pairs, they are available for positioning the Q-RACK system at either: 0º (horizontal), 5º, 45º or 90º (vertical), to meet your testing specifications.
Other accessories include sub-frame kits (set of 8), additional rack components, test panels, and a black box retrofit kit.
Q-RACK Under Glass Exposure Rack Kits
Q-RACK under glass exposure rack systems feature two legs and a special welded, anodized aluminum main frame measuring 3.66 x 1.68 x 0.10m. Six sub-frames are provided, each covered with special 3 mm window glass. All mounting hardware is supplied to hold test specimens in place. Sturdy positioning arms are used to hold frames securely at the correct angle of exposure (see Accessories). Sold in pairs, they are available for positioning the Q-RACK system at either: 0º (horizontal), 5º, 45º or 90º (vertical), to meet your testing specifications.
A black box under glass exposure kit also is available. With its aluminum black box, the rack kit is suitable for testing indoor materials under higher temperature conditions.
Q-Lab offers several accessories for Q-RACK exposure rack kits, which are all available for shipment globally. See LR-3001 – Q-RACK Brochure for photos and more detailed information.
Positioning Arms (Sold in Pairs) – required for installation of Q-RACK kits. Select the angle of exposure:
Panel Flap Assembly (Part FL-3009-K)
The panel flap holds the test panels in place. It is easy to open and close. You can increase the Q-RACK kit’s sample mounting capacity by using additional panel flaps. A vinyl strip separates the exposed and unexposed areas of each panel.
Panel Base Assembly (Part FL-3060-K)
Fits the bottom edge of every rack that uses panel flaps, holding the bottom of the panels in place.
Leg (Part FL-3072-X)
Individual legs may be purchased for custom installations.
Black Box Retrofit Kit (Part FL-3091-K)
Includes all the components and hardware to convert your Q-RACK frame into a black box exposure system.
Used to modify the Q-RACK system to hold non-standard test specimens. Sub-frame kits include eight 81.25cm x 89cm open back sub frame assemblies, or six under glass sub-frame assemblies. Kits are easy to install and adjust for different specimen sizes.
Offset Panel Holder Kits
Used to mount test specimens at an angle, to prevent water from dripping on the sample below. They are adjustable for different sample widths and are available in two sizes.
Standard Practice for Outdoor Weathering of Construction Seals and Sealants
This practice describes outdoor exposure procedures used to determine the weathering durability of building construction, seals and sealants.
Standard Practice for Conducting Exterior Exposure Tests of Paints on Wood
This practice covers procedures to be followed for direct exposure of house and trim paints on new, previously unpainted wood materials to the environment.
Standard Practice for Conducting Exterior Exposure Tests of Paints and Coatings on Metal Substrates
This practice covers procedures to be followed for direct exposure of exterior paints and coatings to the environment when applied to metal surfaces.
Standard Practice for Outdoor Weathering of Plastics
This practice is intended to cover procedures for the exposure of plastic materials to weather. Note 1See Practice G 24 for aging under glass.
Standard Practice for Determining by Exterior Exposure Tests the Susceptibility of Paint Films to Microbiological Attack
This practice provides guidelines for determining the susceptibility of paint films to microbiological attack on exterior exposure. While it is recognized that various organisms may occur on an exposed coating, the specific types of organisms are mainly of academic interest. The degree to which microbiological discoloration occurs is the primary concern.
Standard Specification for Rigid Poly(Vinyl Chloride) (PVC) Siding
This specification establishes requirements and test methods for the materials, dimensions, warp, shrinkage, impact strength, expansion, appearance, and windload resistance of extruded single-wall siding manufactured from rigid (unplasticized) PVC compound. Methods of indicating compliance with this specification are also provided.
Standard Test Method for Deterioration of Geotextiles from Outdoor Exposure
This test method covers evaluating the deterioration in tensile strength and strain after outdoor exposure.
Standard Practice for Atmospheric Environmental Exposure Testing of Nonmetallic Materials
This practice covers procedures to be followed for direct exposure of nonmetallic materials to the environment. When originators of a weathering test have the actual exposure conducted by a separate agency, the specific conditions for the exposure of test and control specimens must be clearly defined and mutually agreed upon between all parties.
