Data Sheet for Speciality Respirators

Data Sheet

Main Features

The 3M Speciality range provides lightweight, effective, comfortable and hygienic respiratory protection against dusts and mists. It also provides additional relief from low levels of organic vapours or acid gases such as sulphur dioxide and hydrogen ﬂuoride (depending on the product type). The convex shape, twin strap design, foam nose seal and aluminium nose clip ensures a good face seal over a range of face sizes. The patented 3MTM Cool FlowTM valve on the 9914 and 9926 and collapse resistant shell featured in all products offer both durable and comfortable protection particularly in hot and humid conditions. These respirators do not require costly and time consuming maintenance.

Approvals

These Speciality respirators have been shown to meet the Basic Safety requirements under Article 10 and 11B of European Community Directive 89/686. EC-Type examination certiﬁcates are in force issued by the British Standards Institution. The product is CE marked.

Standards

Correct Usage

The product has been tested to the European Norm EN149:2001 and has met the requirements of categories shown below.

Product number EN149 performance category

9906, 9913, 9914, 9915 FFP1

9926 FFP2

The main performance tests in this standard are:

• Total Inward Leakage Ten test subjects perform a series of exercises while walking on a tread-mill. The amount of contamination leaking into the respirator through the ﬁlter, face seal and valve in measured. For category FFP1 the leakage must not exceed 22% and for FFP2 the leakage must not exceed 8% for eight of the ten results.

• Filter Penetration The ﬁlter efﬁciency of twelve respirators is tested against a sodium chloride aerosol and a parafﬁn oil aerosol. For the FFP1 category both aerosol penetrations must be below 20%. For the FFP2 category sodium chloride penetration must not exceed 6%.

The respirator may be used in concentrations of solid, water based and non-volatile liquid based aerosols up to 4 times the Workplace Exposure Limit for an FFP1 device and up to 10 times the Workplace Exposure Limit for an FFP2 device. It may also be used to remove the irritation caused by acid gases or organic vapours as speciﬁed in the Applications table at levels below the Workplace Exposure Limit.

(3M has also tested the ﬁlter against Hexane, Sulphur dioxide, Hydrogen ﬂuoride and Chlorine gases although this is not a requirement of the EN149:2001 standard).

• Flammability Four respirators are individually passed through a ﬂame at 800°C +/- 50°C at a speed of 5cm/sec.The respirators shall not continue to burn after removal from the ﬂame.

• Breathing resistance The resistance created by the respirator ﬁlter to an airﬂow of 30 l/m and 95 l/m are evaluated. For an FFP1 device this must not exceed 0.6mbar and

2.1mbar at the respective ﬂows. For an FFP2 device this must not exceed 0.7mbar and

2.4mbar at the respective ﬂows.

• Information A range of information, speciﬁed in this standard, must be provided on the packaging of the product. A full copy of EN149:2001 can be purchased from your national standards body.
