Certain materials, e.g. fabric and yarn, are as a general rule excluded from the requirements in 5.1. However, a tightly packed stuffed component made of these materials cannot be generally excluded from the requirements since it can present the same hazard as a small hard part made of non-excluded materials. A stuffed component should be considered as tightly packed only if it cannot be readily compressed by hand (between forefinger and thumb). Such a component should, however, not be considered hazardous if it does not remain tightly packed also after having been subjected to the relevant tests. This can be the case, for example, when the fabric of a tightly packed stuffed component splays out to reveal the stuffing material when the component becomes detached.
