# Product Test Lab verifies conformance of COVID-19 supplies, military gear

By Beth Reece

                FORT BELVOIR, Va.  –              
A Defense Logistics Agency laboratory known for burning boots, crushing helmets and ripping combat uniforms is also putting COVID-19 surgical gowns through 25 cycles of wash – all in the name of safety and product conformance.                The Product Test Center Analytical at Defense Logistics Agency Troop Support tests the durability of ear loops of KN95 masks during the COVID-19 pandemic June 1, 2020.                            200601-D-D0441-003                            The Product Test Center Analytical at Defense Logistics Agency Troop Support tests the durability of ear loops of KN95 masks during the COVID-19 pandemic June 1, 2020.            SHARE IMAGE:Download ImageImage DetailsPhoto By: Paula Battaglino VIRIN: 200601-D-D0441-003Co-located with DLA Troop Support in Philadelphia, where it tests items primarily in the clothing and textiles and construction and equipment supply chains, the Product Test Center-Analytical is staffed with 27 employees including scientists, engineers and textile technologists.“Think of us as the Consumer Reports for DLA. We don’t just test when there’s a problem; we test to make sure vendors meet contract requirements and warfighters have functional items that work as they’re intended to in the field,” said PTC-A Manager Jamie Hieber.The group performed more testing in 2020 than ever despite a limit on the number of people who could work in the lab simultaneously under pandemic restrictions. And adding time-consuming analysis of items like masks and gowns to the routine hasn’t caused them to miss a single deadline, Hieber added.When the military services began purchasing fabric face masks for troops in the spring, Jessica Raushel’s analytical team was asked to evaluate a fabric one vendor claimed had the ability to bind to chlorine.“If you washed the fabric, it was said to hold on to the chlorine, which would then be released during use of the fabric and potentially give it anti-microbial properties. We were asked to verify that the fabric was indeed treated with this extra finish,” she said.The team wasn’t asked to test the fabric’s protective properties but did provide contracting officers information they needed to make decisions on whether the chlorine-treated fabric posed potential health risks. Hieber said the group takes pride in sharing science-based data even though they don’t always know whether the products tested are later purchased.                The label on a surgical gown is expected for legibility before the first wash and after 25 cycles by the Product Test Center Analytical at Defense Logistics Agency Troop Support.                            210204-D-YE683-002                            The label on a surgical gown is expected for legibility before the first wash and after 25 cycles by the Product Test Center Analytical at Defense Logistics Agency Troop Support.            SHARE IMAGE:Download ImageImage DetailsPhoto By: Paul CrankVIRIN: 210204-D-YE683-002Other mask tests included a durability analysis of head harnesses for KN95s, a mask that’s more easily available in the U.S. than N95s although it offers less protection.Uraina Gray-Scully’s shade and textiles’ team also tests durability of surgical gowns from numerous vendors. The gowns are put through 25 wash cycles using parameters such as water and heat temperatures set by manufacturers. Testing can be rigorous and involve commercial or front-loading washers or be done using basic home washers.“The things we look for range from whether the care label is legible after 25 cycles to the side and neck ties holding up without unraveling, and if there are any holes, rips or tears in the body of the gown,” Gray-Scully said.Gown testing takes over a week with five hour-and-a-half cycles per day for five to six days plus an additional day for staff to write the report.In non-COVID-19 work, much of the lab’s labor revolves around routine checks of performance characteristics for items like combat boots. The tests include an analysis of bond strength between different layers of the sole to ensure it stays together and evaluation of the moisture vapor transmission rate to measure how quickly the boots dry out.                Flame-resistant combat boots are just one type of footwear tested annually by the Product Test Center Analytical at Defense Logistics Agency Troop Support. These boots were tested in 2017.                            170208-D-D0441-001                            Flame-resistant combat boots are just one type of footwear tested annually by the Product Test Center Analytical at Defense Logistics Agency Troop Support.

Before the pandemic, contractors visited the lab as often as five times a week to observe fabric quality and color testing for uniform items. And although contractors run their own tests, DLA ensures contracting officers have unbiased results.“I’m not saying anybody is out to defraud the government, but what if they are?” she asked. “What if we come to a situation where there’s a safety issue or the item doesn’t meet a requirement and it gets into the supply system and someone is hurt or killed because we didn’t do our due diligence?”To adjust to the demand for testing amid pandemic conditions, the staff completed its leap into electronic record keeping and embraced the agency’s move from Skype to Microsoft Teams.                This test tube contains part of an Army sock that is being tested by Defense Logistics Agency Troop Support’s Product Test Center in 2017 to verify the percent of silver contained in the material matches contract specifications.                            170208-D-D0441-002                            This test tube contains part of an Army sock that is being tested by Defense Logistics Agency Troop Support’s Product Test Center in 2017 to verify the percent of silver contained in the material matches contract specifications.            SHARE IMAGE:Download ImageImage DetailsPhoto By: Shannon FradyVIRIN: 170208-D-D0441-002“Teams radically changed how my team communicates,” Raushel said. “We use it to track work assignments and talk to each other as we pass work from one person to the next because people are no longer in the lab continuing projects multiple days in a row.”Raushel created numerous channels in Teams to keep conversations on specific projects organized and encourages use of the @mention function to help members collaborate. Employees all participated in live training sessions when DLA Information Operations announced the software’s rollout, and those who needed more help getting familiar with its capabilities took additional courses in DLA’s Learning Management System.“What we’ve done to support the pandemic is good news,” Hieber said. “But it’s also important to say this lab found a way to continue doing the work it’s always done in spite of all the challenges of the past year. Our customers know they can rely on us.”
