EN149测试及EN149认证简介

EN149测试
该欧洲EN149测试认证标准规定了过滤用作呼吸防护设备的半面罩的最低要求，特别是针对颗粒的最低要求，以及评估面罩符合性所需的实验室和实际性能测试。用于逃生目的的半面罩不属于本标准的范围。
This European Standard specifies the minimum requirements for filtering half masks used as respiratory protective devices, specifically against particles, and the required laboratory and practical performance tests to assess masks’ compliance. Half masks used for escape purposes are excluded from the scope of this standard.
在先前的EN149：1991标准下，分类为FFP1S，FFP2S，FFP2SL，FFP3S和FFP3SL。EN149：2001根据半掩膜的过滤能力将其分为三种类型（例如FFP1，FFP2和FFP3）。满足EN149：2001要求的呼吸器旨在防止固体，水基气雾剂和油基气雾剂的侵害。
Under the preceding EN149:1991 standard, the classifications were FFP1S, FFP2S, FFP2SL, FFP3S and FFP3SL. EN149:2001 classified half masks into three types according to their filtering capacities (e.g., FFP1, FFP2, and FFP3). Respirators that meet the requirements of EN149:2001 are designed to protect against solids, water-based aerosols, and oil-based aerosols.
EN149：2001与EN149：1991的不同之处在于，所有根据EN149：2001测试的产品都必须提供针对固体和液体气溶胶的防护，而EN149：1991仅允许对呼吸器进行针对固体气溶胶的测试。2010年8月1日，对EN 149.2001标准的修正案生效，涉及口罩防尘过滤器的可重复使用性，用“ R”表示可重复使用，“ NR”表示不可重复使用，并标记为EN 149：2001 + A1： 2009年。
EN149:2001 differs from EN149:1991 in that it is mandatory for all products tested in accordance with EN149:2001 to provide protection against solid and liquid aerosols whereas EN149:1991 allows for the testing of respirators against solid aerosols only. On 1 August 1 2010, an amendment to EN 149.2001 standard entered into force concerning the reusability of masks’ dust filters, indicated by “R”, reusable, and “NR”, non reusable, and tagged as EN 149:2001+A1:2009.

EN-149是口罩的欧洲标准之一，而N95口罩则通过了美国国家职业安全与健康研究所（NIOSH）的认证。两种类型的口罩均旨在减少佩戴者的呼吸暴露于空气中的污染物，例如颗粒，气体或蒸气。
EN-149 is one of the European Standard for masks while N95 masks are certified by the US National Institute for Occupational Safety and Health (NIOSH). Both types of masks are designed to reduce wearer's respiratory exposure to airborne contaminants such as particles, gases or vapours.

根据分离空气中颗粒的能力，EN-149口罩分为三类：
The EN-149 masks are classified in three classes depending on the ability to separate air-borne particles:

类      空气流量为95L / min时的分离能力
FFP1    过滤器分离出80％的空气传播颗粒
FFP2    过滤器分离出94％的空气悬浮颗粒
FFP3    过滤器分离出99％的空气悬浮颗粒

Class   Separation ability at 95L/min airflow
FFP1    Filter separates 80% of airborne particles
FFP2    Filter separates 94% of airborne particles
FFP3    Filter separates 99% of airborne particles

满足EN-149标准的FFP2口罩在过滤颗粒方面最接近N95口罩。
FFP2 masks that meet the EN-149 standard are the closest to N95 masks in the ability to filter particles.
