In 2004, the FDA recognized ANSI/AAMI PB70:2003 standard on protective apparel and drapes for use in health care facilities. Surgical gowns must also conform to the ASTM F2407 standard for tear resistance, seam strength, lint generation, evaporative resistance, and water vapor transmission. Because surgical gowns are considered to be a surface-contacting device with intact skin, FDA recommends that cytotoxicity, sensitization, and irritation or intracutaneous reactivity is evaluated.[1]
