Independently Tested Sound Control
PriWatt® switchable glass systems are engineered to provide privacy without sacrificing acoustic performance.
Representative glass assemblies have undergone independent laboratory testing to evaluate airborne sound transmission performance in accordance with recognized industry standards.
Testing was conducted by Riverbank Acoustical Laboratories (RAL), one of North America's leading acoustic testing facilities, utilizing ASTM E90 procedures for laboratory measurement of airborne sound transmission loss.
Independently Tested Smoke Emission Performance
PriWatt® film has undergone independent laboratory testing to evaluate smoke generation characteristics under controlled fire exposure conditions.
Testing was performed by Intertek in accordance with ASTM E662, Standard Test Method for Measurement of Smoke Obscuration Using a Conical Radiant Source in a Single Closed Chamber. The evaluation measured smoke density in both flaming and non-flaming conditions to assess material performance during fire exposure.
The tested PriWatt® film successfully met the performance requirements of NFPA 130 for applicable vehicle components, demonstrating compliance with established smoke emission criteria.
Independently Tested Fire Growth Characteristics
PriWatt® film has undergone independent laboratory testing to evaluate heat release and visible smoke generation under controlled fire exposure conditions.
Testing was performed by Intertek in accordance with ASTM E1354, a recognized test method utilizing oxygen consumption calorimetry to measure fire growth characteristics, heat release rates, and smoke production.
The tested PriWatt® film satisfied the applicable NFPA 130 performance criteria, demonstrating heat release and smoke generation values within the required limits for the evaluated application.
Toxic Gas Analysis
PriWatt® film has undergone independent laboratory evaluation to analyze gases generated during controlled combustion exposure conditions.
Testing was performed by Intertek in accordance with Bombardier SMP 800-C, a recognized methodology used to evaluate toxic gas generation from material combustion. The analysis measured multiple combustion byproducts, including carbon monoxide, hydrogen chloride, hydrogen cyanide, hydrogen bromide, hydrogen fluoride, nitrogen oxides, sulfur dioxide, and other gases relevant to transportation and public occupancy applications.
The testing provides engineers, consultants, and project stakeholders with additional data regarding combustion-generated gas emissions under controlled laboratory conditions.
