Inward leakage test is required for Type 1b suits where the facemask is not permanently attached.NOTE 2
Applicable only when the self-contained breathing apparatus is worn outside the suit and air from the cylinder is fedinto the suit for ventilation.NOTE 3
Applicable for suits where air is vented from the facemask into the chemical protective suit and when the self-contained breathing apparatus is worn outside the suit and air from the cylinder is fed into the suit for ventilation.5 Performance requirements for the whole suit5.1 GeneralChemical protective suits shall fulfil the requirements given in Table 2 when tested as a complete suit.The suit shall be made so that the wearer has freedom of movement and is as comfortable as possible,consistent with the protection afforded by the garment when tested in accordance with 6.25.2 ConditioningThe complete suit shall be exposed:a) for not less than 4 h to an atmosphere of (60 ± 3) °C at 95 % relative humidity; followed byb) for not less than 4 h to a temperature of (-30 ± 3) °C and allowed to return to ambient conditions.It shall then be allowed to return to ambient temperature. If these temperatures are incompatible themanufacturer shall state this and state the designed conditions in the instructions.

Distortion of visionDuring the practical performance test (6.2), the test subject shall be asked to read a sign with four letters100 mm high and 20 mm high, selected at random, at a distance of 6 m.5.5.3 Field of visionDuring the practical performance test (6.2), the field of vision shall be satisfactory.5.5.4 Mechanical strengthThe visor shall not be visibly damaged in such a way as to be likely to affect the performance of the completedevice, when tested in accordance with 6.7.

If the answer is "Yes" continue the test.
If theanswer is "No", take the test subject off the panel and report the fact.6.2.1 Work simulation testDuring this test the following activities shall be done in the simulation of the practical use of the suit, the test shallbe completed within a total working time of 30 min.a)Walking on the level at a regular rate of 6 km/h for 5 min.b)Climbing up and down a ladder (total vertical distance 20 m)c)Filling a small basket (see Figure 1, approximate volume 8 l) with 12 mm chippings (e.g. limestonechippings) or other suitable material from a hopper which stands 1,5 m high and has an opening at thebottom to allow the contents to be shovelled out, and a further opening at the top where the chippings maybe returned. The subject stoops or kneels as he/she wishes and fills the basket with chippings. He/shethen lifts the basket and empties the contents back into the hopper. This is repeated 15 to 20 times in10 min.
