White Papers Learn about the performance of the materials used in the Corporate Traveller product line and how they were tested to ensure the highest level of accuracy and consistent reporting.   Drop Test Data Protecting the notebook and its data is the most important element in the performance of a notebook case. Every day, notebooks are subject to shock and vibration, which could lead to substantial damage to the hard-drive and screen. The best cases prevent potential damage by reducing impact to the notebook. A five-sided drop test measures the G force (a force resulting from acceleration such as gravity) that is experienced when a computer is dropped from five different angles: bottom, left side, right side, back, front. The lower the Gs, the less impact or damage to the notebook.     Abrasion Test Data The American Society for Testing and Materials (ASTM) test is important in determining the durability of material, and its ability to withstand daily wear-and-tear. Targus Corporate Traveller cases are constructed of 1680D nylon, which is both lightweight and strong. The abrasion test concluded that Targus’ Corporate Traveller cases outperformed its competition. Methodology Abrasion testing is done by rotating a test specimen, on a vertical axis, against two revolving abrading wheels. 500g weights were added to each wheel arm for more intense abrasion. The abrading wheels revolve in 1,000 cycle intervals, scraping against the material, until the material shows wear. The higher the cycle number, the better the resistance to abrasion.     Strap Strength Test Data Every day use can affect the strength of shoulder straps over time. All Targus Corporate Traveller cases feature the Equalizer® II strap, which is ergonomically designed for comfort and out-performs its competition in durability and endurance. Results of the Shoulder Strap Strength Test reveal the Targus Equalizer® II strap is more than 1.5 times stronger than its nearest competitor, and more than twice as strong as other brands. Methodology Each end of the shoulder strap was affixed to weights. Starting at 22 pounds, the straps were pulled 250 times; after which, another 22 pounds were added. For each weight increase of 22 pounds, the strap was pulled another 250 times. This process was repeated until the point of failure. The higher the number, the stronger the shoulder strap is.
