公共照明系统的设计和施工

第1章 - 普通条款

第1条 - 应用范围

本文由注释和正文组成。

合同签订后，本文成为合同文本。应包含包括了合同持有方的合同义务。

注释要么为了方便对正文的理解，要么给《专用技术条款手册》的编辑者提供使用建议，但不是合同。《通用技术条款手册》中有明确指示时，这些规定才具有合同特征。

第2条 - 不同类型合同的定义

2.1 选择A - 施工合同

特别是在业主可以完全确定设施特征时，尤其是下几种情况时，选择A：

1. 业主自己设计：主要包括以下几种情况：
   1. 小规模的照明网的建立（小型的农村市镇）；
   2. 现存的照明网的小规模扩充；
   3. 大规模扩充或是建立一个照明网，共同发起确定装置的光度和几何特征的项目。
2. 与承包商签订设计合同签就自主设计的情况。

在其它情况下选择B

2.2 选择B - 设计合同和施工合同

在此类合同中，需要根据初步设计（APS）来对设施进行研究设计，由合同中标人负责确定设施的尺寸。合同中标人需具备大量的实施成果。中标人应负责工程的施工以及工程验收的预先检测。

第3条 - 参考

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of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.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.
