<P>新民规对于卫生间分区的规定改变了,但是规定写得很有问题,产生了很多疑义。比如对于无盆淋浴来说,规范的图没有画出2区的范围,说明却写出了2区的定义方法。假如真的考虑这个2区的话,竟然要半径1.8m的2.25m以下区域无法安装插座,这对于普通住宅来讲实在是很困难了。带着问题查看了iec规范原文,发现iec规范其实说明的已经很清楚了:以下引自IEC 60364-7-701-2006</P>
<P>701.30.3 Description of zone 1<BR>Zone 1 is limited<BR>a) by the finished floor level and the horizontal plane corresponding to the highest fixed<BR>shower head or water outlet or the horizontal plane lying 225 cm above the finished floor<BR>level, whichever is higher,<BR>NOTE 1 In Belgium, Denmark, Hungary and Italy, if the bottom of the bath tub or shower basin is located<BR>higher than 15 cm from the floor level, the horizontal plane is located 225 cm above the bottom of bath tub or<BR>shower basin.<BR>NOTE 2 In the Netherlands 225 cm is replaced by 260 cm.<BR>NOTE 3 In the Czech Republic and in Spain the zone 2 is considered above the zone 1 as far as the ceiling or<BR>the horizontal plane lying 300 cm above the finished floor level, whichever is higher.<BR>b) by the vertical surface:<BR>– circumscribing the bath tub or shower basin (see Figure 701.1),<BR>– at a distance of 120 cm from the centre point of the fixed water outlet on the wall or<BR>ceiling for showers without basin (see Figure 701.2 ).<BR>Zone 1 does not include zone 0.<BR>The space under the bath tub or shower is considered to be zone 1.<BR>NOTE 4 In Spain, and for showers without basin, where the water outlet is fixed the vertical limit is fixed at 60 cm<BR>around the water outlet.<BR>NOTE 5 In Spain, the space under the bath tub or shower basin accessible without the use of a tool is considered<BR>to be zone 1. If it is accessible only with the use of a tool, it is considered to be neither zone 0, nor 1 nor 2.</P>
<P>701.30.4 Description of zone 2<BR>Zone 2 is limited<BR>a) by the finished floor level and the <FONT color=#ff0033>horizontal plane corresponding to the highest fixed<BR>shower head or water outlet</FONT> or the horizontal plane lying 225 cm above the finished floor<BR>level, whichever is higher,<BR>NOTE 1 In the Netherlands, 225 cm is replaced by 260 cm.<BR>b) by the vertical surface at the boundary of zone 1 and the parallel vertical surface at a<BR>distance of 60 cm from the zone 1 border ( see Figure 701.1).<BR><FONT color=#ff0033>For showers without basin, there is no zone 2</FONT> but an increased zone 1 is provided by the<BR>horizontal dimension of <FONT color=#ff0033>120 cm</FONT> mentioned in the second dash of 701.30.3 b) (see Figure<BR>701.2).<BR>NOTE 2 In Spain, zone 2 exists in any case.</P> |
