URS Products and Testing

In today's fast-paced technological landscape, audio and video play a crucial role in our daily lives. From home entertainment systems to professional audiovisual setups, the quality and performance of audio and video devices greatly impact our overall experience. This article examines the significance of audio and video testing, highlighting its role in improving performance and user satisfaction. Ensuring Quality and Consistency: Audio and video testing labs play a vital role in ensuring that audiovisual products meet rigorous quality standards. By conducting comprehensive testing procedures, these labs can identify and address any issues related to sound quality, image clarity, colour accuracy, and other performance parameters. This ensures that consumers receive products that consistently deliver the best audio and video experience. Compliance with Industry Standards: Audio and video testing laboratories adhere to industry standards and regulations to assess the performance of...

Batteries and cells testing laboratories play a critical role in making sure every battery—whether in a toy, a smartphone, a solar backup, or an electric vehicle—is safe, reliable, and compliant with regulations before it reaches users. What battery and cell testing labs do Batteries and cells testing labs are specialised facilities that evaluate individual cells, battery modules, and full packs for performance, durability, and safety under controlled conditions. These labs support industries such as consumer electronics, automotive (especially EVs), renewable energy storage, medical devices, and backup power systems. Key objectives include: ● Verifying that batteries deliver their rated capacity, voltage, and power over many charge–discharge cycles. ● Demonstrating that products meet national and international safety and transport regulations before certification and market launch. Types of tests performed Labs run a mix of routine performance tests and aggressive “abuse” tests to und...

 When CE marking is mandatory CE marking certification is legally required only for products falling under one or more EU directives or regulations that explicitly demand it. If a product is not covered by such legislation, CE marking must not be used, even voluntarily. Typical product groups include: ● Electrical and electronic devices (e.g., under the Low Voltage Directive, EMC Directive, and Radio Equipment Directive). ● Machinery, toys, personal protective equipment, pressure equipment, and certain construction products. ● Many consumer goods may impact user safety, health, or the environment when placed on the EU market. Responsibilities of manufacturers and other actors The CE mark is primarily the responsibility of the manufacturer or the entity placing the product on the EU market. Key responsibilities: ● Manufacturers must identify all applicable EU legislation, carry out conformity assessment (self-assessment or via a notified body), and compile a complete technical docu...

 Why EMI/EMC testing labs matter Because homes, vehicles, hospitals, factories, and offices are filled with tightly packed electronics, uncontrolled emissions, or poor immunity can cause malfunctions, data loss, or safety risks. EMI/EMC labs help manufacturers demonstrate compliance with regulatory limits, reducing product failures, recalls, and legal liability. These labs are crucial for: ● Market access under frameworks like the EU EMC Directive and FCC EMC rules for many categories of electronic devices. ● Sensitive sectors such as medical devices, automotive, aerospace, defence, and industrial control, where interference can impact safety-critical functions. Key tests performed in EMI/EMC labs EMI/EMC testing laboratories typically offer a structured set of emissions and immunity tests based on international standards (for example, IEC/EN 61000 series and CISPR standards). Typical emissions tests: ● Radiated emissions: Measuring RF energy radiated into the air using antennas ...

 Electric vehicle (EV) testing laboratories are specialised facilities that evaluate the safety, performance, durability, and interoperability of electric vehicles and their critical subsystems—especially batteries, power electronics, drivetrains, and charging infrastructure. What electric vehicle testing labs do EV testing labs bridge the gap between simulation and real-world operation by subjecting components and complete vehicles to controlled electrical, thermal, and mechanical stresses. Their purpose is to ensure that EVs meet safety regulations, perform reliably over time, and integrate smoothly with charging networks and the power grid. Key objectives include: ● Verifying that batteries, inverters, motors, and chargers deliver their rated power, efficiency, and range across varying conditions. ● Demonstrating compliance with evolving standards for safety, cybersecurity, and grid/charging interoperability. Core test areas in EV labs Modern EV labs usually organise their work ...

 Drones now operate in critical domains such as defence, agriculture, logistics, infrastructure inspection, and emergency response, where failures can lead to financial loss, safety incidents, or regulatory violations. Testing labs reduce these risks by subjecting UAVs to controlled technical evaluations that mirror real operating environments and regulatory expectations. Core test domains in a drone testing lab A professional drone testing laboratory typically works across multiple engineering domains instead of treating the UAV as a single black box. Main areas include: ● Propulsion and performance testing: Measuring thrust, torque, power draw, RPM, and efficiency to optimize motor–propeller combinations and payload capacity. ● Flight stability and control: Evaluating hover accuracy, response to wind, manoeuvrability, and autonomous flight modes using simulators, indoor nets, and outdoor ranges. ● Structural and environmental tests: Vibration, shock, temperature, humidity, rain,...

Although the design engineer can directly measure all of the cell parameters they desire, this is not always practical or feasible. By fully discharging the battery and measuring the energy output, for instance, it is possible to determine how much charge is still in the battery, or the State of Charge (SOC). Test Conditions In order to obtain repeatable results and make meaningful comparisons, the test conditions must be clearly defined. Qualification Testing Before a cell or battery is permitted for use in a product, qualification testing is used to ascertain whether it is suitable for the intended use. Prior to the product being authorised for distribution to the customer, a finished battery pack must also pass  Cell testing  as a second stage of qualification. Environmental Testing The safety standards listed below incorporate typical tests. They are made to put the product through all of the environmental conditions that it is likely to experience over the cour...
