46、g URL: Foreword - Supplementary informationThe committee responsible for this document is ISO/TC 199, Safety of machinery.This second edition cancels and replaces the first edition (ISO 14120:2002), which has been technically revised. The main changes from the previous edition are as follows. Defini

47、tions have been brought into line with ISO 12100. The figures showing examples of guards have been updated where appropriate. Clause 5 has been updated with new references to ISO 13855 and ISO 14119. Requirements on the removal of guards have been amended. Subclause 5.3.9 describes requirements for

48、the removal of fixed guards only with a tool. In addition, there is a requirement that fixed guards be designed to prevent easy removal. The subclause about impact and ejection resistance (5.4) has been strengthened. Subclauses on Climbing (5.18), Retained fastenings (5.19), Warning signs (5.21), Co

49、lour (5.22) and Appearance (5.23) have been added. Clause 6 has been amended and updated to better include cover combinations of different guards or of guards with other devices. Selection of guards according to the number and size of the hazards (6.3) has been changed and updated. Subclause 6.4.4.2, where access is required during the working cycle, has been cha
