9、ANDARD JIS B 9711 : 2002 (IS0 13854 : 1996) Safety of machinery- Minimum gaps to avoid crushing of parts of the human body Introduction This Japanese Industrial Standard has been prepared based on the first edition of IS0 13854 Safety of machinery-Minimum gaps to avoid crushing of parts of the human
10、 body published in 1996 without modifying the technical contents. The foreword of the original International Standard has been excluded because it is not part of the provisions. The portion of the foreword of the original International Standard that is speci- fied in other standard have been exclude
11、d. One method of avoiding the hazard of crushing of parts of the human body is to make use of the minimum gaps specified in this Standard. In specifying minimum gaps, a number of aspects have to be taken into consider- ation, such as: - accessibility of the crushing zones; - anthropometric data, tak
12、ing into account ethnic groups likely to be found in the countries concerned; - technical and practical aspects. this Standard, could be improved. If these aspects were further developed, the current state of the art, reflected in 1 Scope The object of this Standard is to enable the user (e.g. stand
13、ard makers, designers of machinery) to avoid hazards from crushing zones. It specifies minimum gaps relative to parts of the human body and is applicable when adequate safety can be achieved by this method. This Standard is applicable to risks from crushing hazards only and is not appli- cable to ot
14、her possible hazards (e.g. impact, shearing, drawing-in). NOTES 1 For impact, shearing or drawing-in hazards, for example, additional or other measures need to be taken. 2 The International Standard corresponding to this Standard is as fol- lows. In addition, symbols which denote the degree of corre
15、spondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) ac- cording to ISO/IEC Guide 21.

This hazard will be generated if - two movable parts are moving towards one another, or crushing zone Zone in which the human body or parts of the human body - one movable part is moving towards a fixed part.

Methodology for the use of this Standard The user of this Standard shall: a) identify the crushing hazards; b) assess the risks from these
23、 hazards in accordance with ISO/DIS 12100-1, pay- ing particular attention to the following: - where it is foreseeable that the risk from a crushing hazard involves differ- ent parts of the body, the minimum gap given in table 1 relating to the largest of these parts shall be applied see also d)l, -
24、 the unpredictable behaviour of children and their body dimensions if chil- dren are included in the population at risk, - where parts of the body could enter the crushing zone in a configuration other than those indicated in table 1, PROTECTED BY COPYRIGHT Copyright Japanese Standards Association P

26、xtreme tem- peratures) or tools have to be taken into account, - whether machinery will be used by persons wearing thick-soled footwear (e.g. clogs) which will increase the effective dimension of the foot; select from table 1 the appropriate minimum gap relating to the body part at risk (see also an
27、nex A); if adequate safety cannot be achieved by the minimum gaps selected from table 1, other or additional measures and/or means shall be used (see e.g. ISOLDIS 12100- 1, ISO/DIS 12100-2 and JIS B 9707 : 2002). If the minimum gap for the largest expected body part cannot be achieved, the following
28、 example gives one particular means of restricting access to smaller body parts. Example : Access of larger body parts to the crushing zone can be prevented by the use of protective structures having a restricted opening, as indicated in figure 1. The possibility of access to a crushing zone for a p
29、articular part of the body is dependant on the following: - the gap a between the fixed and moving part or between two moving parts; - the depth b of the crushing zone; - the dimensions c of the opening in the protective structure and is distance d from the crushing zone. NOTE : The dimensions for o
30、penings in relation to safety distances can be found in JIS B 9707. For certain applications there may be justifiable reasons to deviate from the mini- mum gaps in table 1. Standards dealing with these applications indicate how ad- equate safety can be reached. 4.2 Values the human body. For the sel
