During these unique times, DDL is committed to providing you with fast, accurate, and high quality testing. DDL provides testing on the following products that are vital in the fight against COVID-19.
Ventilator Components
Ventilators, ventilator tubing connectors, and ventilator accessories must be determined to meet the applicable criteria for safety and performance.
DDL provides testing to the following standards:
- ISO 5356–1 – Anaesthetic and respiratory equipment — Conical connectors — Part 1: Cones and sockets
- ISO 5359 – Anaesthetic and respiratory equipment — Low-pressure hose assemblies for use with medical gases
- ISO 18082 – Anaesthetic and respiratory equipment — Dimensions of non-interchangeable screw-threaded (NIST) low-pressure connectors for medical gases
Medical Masks
Testing for surgical facemasks and general-use medical masks is essential to ensuring performance properties are validated to support marketing label claims and to classify these mask types.
DDL provides testing to the following standards:
- ASTM F2100 – Standard specification for performance of materials used in medical face masks
- EN 14683 – Medical face masks. Requirements and test methods
Medical Gowns
Tensile and bursting strength or liquid penetration tests are paramount to ensure the maximum efficacy against infections, especially in hospitals.
DDL provides testing to the following standards:
- ASTM F1868 – Standard test method for thermal and evaporative resistance of clothing materials using a sweating hot plate
