1 Scope This standard specifies general requirements for the design and construction of guards which are mostly used to protect personnel from mechanical hazard and harm. This standard is mainly applicable to machines manufactured after the issuance of this standard. It shall pay attention to guard application in order to minimize non- mechanical hazard. This standard is applicable to fixed and movable guards. This standard is not applicable to the components of automatic interlocking device. Interlocking device shall be stipulated by GB/T 18831. This standard has no requirements for dedicated system capable of moving and lifting materials, such as Roll Over Protection Structure (ROPS) and Falling Object Protective Structures (FOPS) 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments to, or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of these documents is applicable. For undated references, the latest edition of the normative document is applicable to this standard.

Part of these terms and definitions is determined by GB/T 15706.1. 3.1 Guard The part of machinery which is dedicated to providing protection through object obstacle. According to their structures, the guards may be shell, shield, screen, door, enclosing guard and so on. Note 1: The functions of guards may be: ——Independent functioning: It works only when it is closed; ——Functioning jointly with interlocking device with or without guard locking. Under such conditions, the guards will guarantee protection function at any position (See 3.5). Note 2: The "closed" refers to "staying in position" for fixed guard. [GB/T15706.1—1995, 3.22] 3.2 Fixed guard The guard stays in position (namely, closed) by the following mode; ——Permanently fixed (like welded); ——Or fixed by fastening pieces (screw, bolt, etc.). It will be impossible to dismantle or open it without tools. [GB/T 15706.1—1995, 3.22.1] 3.2.1 Enclosing guard The guard to prevent entering guard from all directions (See Figure 1)
