S5.2.4警告装置三角形部分的每个顶点的半径应不小于0.25英寸且不大于0.50英寸。<br><br>S5.2.5必要时，所有边缘应倒圆或倒角，以减少割伤或伤害使用者的可能性。<br><br>S5.2.6设备应完全由三角形部分和支撑和封闭所需的附件组成，没有其他可见的形状或附件。<br><br>S5.3颜色​​。<br><br>S5.3.1在照明装置是带有钨丝的灯的情况下，警告装置上的红色反射反射材料的颜色在按照S6.1进行警告装置调节之前和之后均应具有以下特征。在2856°开尔文色温下运行。以国际照明委员会（CIE）1931标准比色观察器系统（CIE色度图，图4）表示，红色反射型反射材料的色度坐标应位于光谱轨迹和光谱线所界定的区域内。以下等式定义的图表：

S5.2.4 Each vertex of the triangular portion of the warning device shall have a radius of not less than 0.25 inch and not more than 0.50 inch.<br><br>S5.2.5 All edges shall be rounded or chamfered, as necessary, to reduce the possibility of cutting or harm to the user.<br><br>S5.2.6 The device shall consist entirely of the triangular portion and attachments necessary for its support and enclosure, without additional visible shapes or attachments.<br><br>S5.3 Color.<br><br>S5.3.1 The color of the red reflex reflective material on the warning device shall have the following characteristics, both before and after the warning device has been conditioned in accordance with S6.1, when the source of illumination is a lamp with a tungsten filament operating at 2856° Kelvin color temperature. Expressed in terms of the International Commission on Illumination (CIE) 1931 standard colorimetric observer system (CIE chromaticity diagram, Figure 4), the chromaticity coordinates of the red reflex reflective material shall lie within the region bounded by the spectrum locus and the lines on the diagram defined by the following equations:
