Both marks demonstrate that the product that bears it has met the minimum requirements of widely accepted product safety standards as determined through the independent testing of a Nationally Recognized Testing Laboratory (NRTL). And, as part of that testing regimen, the product manufacturer has agreed to periodic follow-up inspections to verify continued compliance. So, the only real difference between the marks is in the service, and services, of the testing laboratory behind them. It's here that ITS ETL SEMKO's clients enjoy the real differences between UL and ETL. ETL custom-tailored testing, quick turnarounds, and flexible work methods are literally changing the face of the industry by promoting an environment where the testing lab and product manufacturer work more collaboratively - bringing products to market more quickly, more smoothly, and more cost-effectively than ever before.
