In the last post on the QUV/uvc, we discussed two published standards with UVC exposure protocols, covering quite different applications. In this post, we’ll discuss designing QUV/uvc exposure methods for materials that encounter UVGI protocols in us...

In our first post on the QUV/uvc, we discussed why the QUV/uvc was designed and the differences between it and the QUV accelerated weathering chamber used for generations to conduct UV weathering studies. In this post, we’ll go over published UVC exp...

The QUV/uvc is a new version of the QUV accelerated weathering tester. The main difference between it and other QUV models is that it is designed to operate UVC lamps, which are functionally identical to those used in ultraviolet germicidal irradiati...

A very common and fundamental question to ask when beginning a weathering and/or corrosion testing program: “What kind of accelerated test should I run?” It’s a critical question to answer, but there isn’t one general answer that covers all customer ...

This very common question is often well-meaning but can at times limit one’s understanding of weathering of materials. It’s like asking if someone is interested in a car or a vehicle - a car is a type of vehicle, but not every vehicle is a car. Likew...

Background and Problem StatementQ-Lab worked to develop a correlative accelerated and outdoor testing program for an American manufacturer of high-end outdoor furniture. This company’s products are commonly installed in public places such as shared o...

A) QUVThe QUV weathering tester is fast and economical. Fluorescent UV lamps provide the best simulation of solar UV. However, the QUV lacks the longer wavelengths necessary for testing certain materials.Short-Wave UV: The QUV tester provides the bes...

QFS-40 and UVB-313EL lamps are both used in QUV accelerated weathering testers to provide fluorescent UV light that includes a significant UVB component for faster testing. The diagram below shows that both have similarly-shaped spectral power distri...

Are you ready to start your first weathering or corrosion test program but aren’t sure how the process works? Don't worry – Q-Lab is here to make it simple for you! Here are a few important tips to get things rolling.The first step is to contact us. ...

The Big Payback on Weathering & Light Stability Testing: Quite often, weathering and light stability testing yields huge returns on investment. Here's our list of the top 10 returns you can get from a relatively modest outlay on testing.Avoid Cat...
