| MS004: Load Analysis | A fully loaded component cart shall weigh less than 175 lbs. | Should weigh less than 100 lbs. | Use a scale to measure the fully loaded component cart. |
| MS005: Component Cart Tipping Resistance | The fully loaded component cart shall pose no risk of tipping over when a weight of 30lbs is cantilevered 1.5 feet from the side of the cart. | The fully loaded component cart should pose no risk of tipping over when a weight of 40lbs is cantilevered 1.5 feet from the side of the cart. | Using testing apparatus and weights to hang weight from the side of the cart. |
| MS006: Disinfectant Coverage | The system shall increase the surface area covered while using electrostatic by 20%. | The system should increase the surface area covered while using electrostatic by 60%. | Rejected null hypothesis with statistical confidence interval of 90% and report of percentage increase comparison of charge/no charge. |
| MS007: Affordability | Production cost shall be ≤$1000. | Production cost should be ≤$700. | Final bill of materials. Production of the prototype fits within the allocated budget for materials and initial testing. |
| MS008: Cart Push Force | Initial push force shall be less than 50lbs with a sustained push force less than 40lbs. | Initial push force should be less than 40lbs with a sustained push force less than 35lbs. | Force sensor testing of fully loaded cart. |
| MS009: Pull Force | Pull force shall allow 75% of workers to pull the cart and its contents. | Pull force should allow 80+% of workers to pull the cart and its contents. | Cart weight and height dimensions compared to ergonomic standards provided by OSU. |
| MS010: Disinfectant Storage* | Component cart shall store 2 gallons of fluid. | Component cart should store 1 gallon of fluid. | Volumetric/tape measurement. |
| ES001: Safety Factor | The system will not pose any risk of injury via electrical shock to the user. | N/A | Recording static output of the attachment with a grounded probe. Compare to UL standards for high voltage exposure. |
| ES002: System Operational Distance | The sprayer shall be able to operate more than 25 feet from an outlet. | The sprayer should be able to operate more than 50 feet from an outlet. | Measure length of the internal electronics’ power cord. |
| ES003: Stop Switch | The component cart shall have a stop switch to cut power in the system. | The wire connected to the ionizer should have a stop switch to cut power in the system. | Operate system and while in use, hit the stop switch to show that power is no longer going to the device. |
* MS010 was mistakenly written to have the number of gallons stored switched
