The National Institute for Occupational Safety and Health has proposed to amend the certification rules for half mask air-purifying particulate respirators. The amendment would require the certified respirator to fit a minimum percentage of the intended users. The fail/pass rate for a respirator fitting a worker population has not been part of the certification process for particulate respirators since 1995. The amendment would also add a new requirement for the manufacturer to inform whom the respirator is intended to fit.
美国国家职业安全卫生研究所提议修订半面罩式空气净化微粒呼吸器的认证规则。修订内容将要求认证呼吸器适合至少一定比例的预期使用者。自 1995 年以来，呼吸器适合工人群体的失败/通过率一直不是微粒呼吸器认证过程的一部分。修订内容还将为制造商添加一个新要求，即告知呼吸器适合哪些人使用。
