NEN-EN 1073-2:2002 - Protective clothing against radioactive contamination - Part 2: Requirements and test methods for non-ventilated protective clothing against particulate radioactive contamination.

EN 1073-2:2002 part 2 specifies the requirements and test methods for non-ventilated protective clothing designed to protect the wearer against particulate radioactive contamination.

Results from the inward leakage test can be used to determine the clothing's Nominal Protection Factor (NPF).
While this type of clothing is intended to protect the wearer's body, arms, and legs, this clothing may also be worn with accessories - such as boots, gloves, and respiratory protective equipment (RPE) - that provide specialised protection for other areas of the wearer's body. The requirements for specialised protection are described in other European Standards.

The inward leakage test method is defined in EN ISO 13982-2 Method B and is essentially the same as the Type 5 test, with the highest mean value of Total Inward Leakage for one activity (i.e., the highest TIL(E) percentage and the highest TIL(A) percentage) used to determine the NPF as defined in the table below.

Non-ventilated protective clothing shall be classified according to EN 1073-2:2002
