Vehicle Interior Air Quality Testing
Underwriters Laboratories Inc.
Hundreds of volatile organic compounds (VOCs), which off-gas from the materials and finishes used in car interiors, can be present in the air inside a new vehicle. VOCs can cause odor complaints and have been linked to numerous health concerns. As the demand for healthier products increases, vehicle manufacturers that tell a compelling sustainability story can capitalize on a significant opportunity to grow market share. UL helps manufacturers capture value for their sustainability efforts, mitigate risks and comply with increasingly complex regulations.

Sound Level Calibrator
511E
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.
