8.All the hard material masking on the face( goggles, a space helmet or welding mask).

Operation

Ensure the loading device shall be a rigid metal disk 1.125±0.015 in. (0.380 mm) in diameter and 0.375 in. (9.52 mm) in thickness. The perimeter of the disk shall be rounded to a radius of 1 ⁄ 32 in. (0.8 mm) to eliminate irregular edge.

The disk shall be attached to an appropriate compression scale having an accuracy of ±0.5 lb (2 N). The disk shall be positioned so that the flat contact surface is parallel to the surface under test. The required force shall be applied evenly within 5 s through the disk. This load shall be maintained for an additional 10 s. The toy is to rest on a flat, hard surface in any convenient position during the test.

Apply a compression force according to the standard (table 1)through a rigid metal disc with a diameter of (30 ± 1,5) mm/28.6±0.38mm to the area to be tested. Determine whether the casing of toys intended for children too young to sit up unaided has separated into parts or cracked . Determine whether small parts hazardous sharp edges, hazardous sharp points or hazardous driving mechanisms have become accessible .
