1. 应用范围

本欧洲标准规定了永久性或临时性道路标记产品——后向反射反光路钮的初始性能要求和试验室试验方法。

2. 标准的参考

本标准包含其它刊物的条文中注明日期的参考或没有注明日期的参考。这些标准的参考在正文的合适地方注明，刊物在下面已编号。对于注明日期的参考，这些刊物中的任意一个往后的修正或改正只能当它们并入修正或改正时才能应用于此标准。对于未注明日期的参考,参考刊物的最新版本。

3. 定义

根本本标准的需要，适宜采用 CIE 刊物 17.4 的定义及以下的定义：

3.1. 后向反射反光路钮（在此项标准中称其为路钮）

水平标志设施通过后向反射器（见 3.2）反射入射光线以便提醒驾车人，引导或通知道路使用者。

注：后向反射反光路钮可以由一个或多个集成元件组成，可以粘在路面，在路面固定或嵌入路面。后向反光部分可以单向或双向，可压降或不可压降。这种设施可分为持久型（P 型）和临时型（T 型）。

3.2. 后向反射器

可以将入射光线按其平行射方向反射回去的设施。

注：后向反射器材可以是玻璃（1 型），塑料（2 型），或塑料以及耐磨表面（3 型）。其后表面配备反射涂层。

3.3. 无压降系统的路钮

通常此类路钮为刚性的，在交通中不会发生形变（A 型）。

3.4. 可压降路钮

设计的路钮包括一个或多个会在交通中发生形变的部分，交通载荷消失后会恢复其几何原状（B

Foreword

This document (EN 10216-3:2002) has been prepared by Technical Committee EC/TC 29, "Steel tubes and fittings for steel tubes", the secretariat of which is held by UNI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.

ISO 657-1 : 1988 (E)

Table 1 — Dimensions and sectional properties of hot-rolled equal-leg angles (concluded)

NOTES

1. Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
2. For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
3. The sectional area has been calculated using the formula

   S = [l/2 A - l) + 0,214 6 (r_root² - 2r_toe²)] × 1/100

   where
   

   S is the sectional area, in square centimetres;
   

   l is the thickness, in millimetres;
   

   r_root is the root radius, in millimetres;
   

   r_toe is the toe radius, in millimetres;
   

   A is the leg length, in millimetres.

4. Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
