– re-wording of Clause 8: Categories of optical fibres;

– removal of Clause 10: Cross-reference of former test designations to current documents;

– removal of the bibliography

The following dates were fixed:

– latest date by which the EN has to be implemented

at national level by publication of an identical

– latest date by which the national standards conflicting

Annex ZA has been added by CENELEC

Endorsement notice

The text of the International Standard IEC 60793-1-1:2008 was approved by CENELEC as a European Standard without any modification

INTRODUCTION

Publications in the IEC 60793-1 series concern measurement methods and test procedures as they apply to optical fibres

Within the same series, several different areas are grouped, as follows:

General and guidance

1 Scope and object

This part of IEC 60793 lists and gives guidance on the use of documents giving the uniform requirements for measuring and testing optical fibres, thereby assisting in the inspection of fibres and cables for commercial (mostly telecommunications) purposes

The individual measurement and test methods are contained in the different parts of the IEC 60793 series They are identified as IEC 60793-1-X, where "X" is an assigned sub-part number, indicating its affiliation to IEC 60793-1

In general, measurements and tests methods apply to all class A multimode fibres and Class B single-mode optical fibres covered by the IEC 60793-2 series, although there may be exceptions Clause 1 of each part of IEC 60793 contains the scope for each particular attribute

5 Standard atmospheric measurement and test conditions

Standard atmospheric conditions need to be controlled within some range to ensure proper correlation of data obtained from measurements and tests conducted in various facilities Conduct measurement and test conditions under the following atmospheric conditions, unless otherwise specified In some cases, special ambient conditions may be needed and can be specified in the detail specification

Table 1 gives the standard range of atmospheric conditions for carrying out measurements and tests:

Table 1 ± Standard range of atmospheric conditions

Atmospheric pressure

Keep variations in ambient temperature and humidity to a minimum during a series of measurements

6 Calibration guidance

The process of calibration may be defined as the set of operations which establish, under specified conditions, the relationship between values indicated by a measuring system and the known values of a reference material Once established, this relationship may be used to adjust the measuring system to correct for measurement bias Adjustment of the system may, for example, take the form of hardware or a software adjustment

Follow the instructions given in the test procedure documents as may be necessary for calibration and adjustment of the apparatus to ensure successful application of the documents If suitable reference materials do not exist, then consideration should be given to

an appropriate strategy to minimise measurement uncertainty

Record relevant information of the calibration process, such as the calibrated value and uncertainty of the reference material or test equipment used

Trang 13

– 10 – 60793-1-1  IEC:2008(E)

7 Reference test methods

Several attributes have an agreed-upon reference test method (RTM) This is the method that shall be used to settle disputes

8 Categories of optical fibres

The measurement methods and test procedures indicated in this standard apply to fibre categories described in Clause 5 of IEC 60793-2, as appropriate

9 Packaging

For handling and shipping of optical fibres, the packaging device shall meet the following requirements:

a) winding techniques shall enable the optical fibre to withstand transport and specified environmental conditions;

b) the possibility of measuring the dimensions, transmission and optical characteristics of the optical fibre without removal of the fibre from the packaging device shall be indicated; c) reel dimensions shall be provided to the customer
