4、r openings with a minor dimension equal to or greater than 34,9 mm (1-3/8 in), compliance shallbe checked by inspection and by applying the test probes of Annex 101.DVA with a force of 11,1N (2,5 lb). The probes shall be rotated or angled to any possible position before, during, or afterinsertion th

These probes represent childrenshands and arms, and are intended to determine if there is a hazard with respect to moving parts of theappliance. Tolerances are needed for the manufacturing o

20、f these probes, so Annex 101.DVF has beendeveloped to show applicable tolerances.In addition, the inch-pound dimensions for the various parts of the probes that are currently in Figures101.DVA.1 and 101.DVA.2 were determined via a “soft conversion” of the SI dimensions. Since these I-Pdimensions are

21、nt accurate enough, they are being removed.Copyright 2017 UL LLCUL LLC, in performing its functions in accordance with its objectives, does not guarantee or warrant thecorrectness of Certification Requirement Decisions it may issue or that they will be recognized or adoptedby anyone.
