General Description

The QUV Accelerated Weathering Tester is a laboratory simulation of the damaging effects of weathering. It is used to predict the relative durability of materials exposed to the outdoor environment. Rain and dew are simulated by a revolutionary condensation system and/or a water spray system. The damaging effects of sunlight are simulated by fluorescent UV lamps. Exposure temperature is automatically controlled, as is the daily sequence of UV periods and moisture periods. In a few days or weeks, the QUV can produce damage that might occur over months or years of outdoor exposure. Deterioration observed includes fading, chalking, cracking, crazing, hazing, blistering, gloss loss, strength loss, and embrittlement.

The QUV/spray conforms to the following standards (among others).

ASTM G-154 (Previously G-53}, Light/Water Exposure of Nonmetallic Materials

ASTM D-4587, Light/Water Exposure of Paint

ASTM D-4329, Light/Water Exposure of Plastics

ASTM D-4799, A. Weathering of Bituminous Roofing Materials

BS2782, Part 5, Methods 5408 (Exp. to Lab Light Sources)

ISO 4892 Plastics D Plastics Exposure to Lab Light Sources

SAE J2020, Accelerated Exposure of Automotive Exterior Materials

General Motors TM-58-10

Remarks:

1. Minimum and maximum black panel temperatures are dependent on irradiance settings and ambient temperatures.

2. Water consumption values are dependant upon test and lab conditions. Values shown are maximum for many common standards.

3. Actual shipping weights will be higher and depend upon whether the shipment is domestic, ocean, or air.

Utilities and other required parts:

Consumable items:

1. QUV Irradiance Smart Sensor, UV (UC10/UV) -To be replaced annually to ensure ISO compliance.
