Often such results are already included in national specifications as recommended values, so that the calculation may be based on these values generally used in the country in question; a survey of such values is given in this section. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: or or. Gives guidance for evaluating the photobiological safety of lamps and lamp systems including luminaires. For dated references, only the edition cited applies. This fourth edition cancels and replaces the third edition published in 1999 and constitutes a technical revision.

This publication shall not apply to standard voltages of components and parts used within electrical devices or items of equipment. However, if the laser system within the laser product is operable when removed from the end product, the requirements of this Part 1 apply to the removable laser system. It bears the edition number 1. Material declaration for products of and for the electrotechnical industry Specifies the procedure, content, and form relating to material declarations for products of companies operating in and supplying the electrotechnical industry. Graphical symbols for diagrams Contains graphical symbols for use in electrotechnical diagrams. Part 1 has been updated to include contemporary concepts of usability engineering, while also streamlining the process. It excludes voltage transients, such as those due to system switching, and temporary voltage variations.

Clause 4 and its subclauses summarize the operating conditions used in various countries. The database also provides classified views by shape, function and application and a search facility. Particularly, in the case of soil thermal resistivity, it is well known that this quantity is very sensitive to soil moisture content and may vary significantly with time, depending on the soil type, the topographical and meteorological conditions, and the cable loading. It is also recommended that only one of the two series of nominal voltages given for Series I should be used in any one country. In such cases, the relevant recommendations must specify the limit to which the normal operation of this equipment can be ensured.

A bilingual version of this publication may be issued at a later date. It is obviously possible to compare the results of two calculations of current rating only when the assumptions made and the numerical values of the parameters are known. Various search and navigation facilities allow for easy retrieval of graphical symbols. The following procedure for choosing the values for the various parameters should, therefore, be adopted. The values are voltages between phases. For example, edition numbers 1. Q2 Please tell us in what capacity ies you bought the standard tick all that apply.

The values indicated are voltages between phases. This sixth edition cancels and replaces the fifth edition published in 2005. Please contact the Customer Service Centre see below for further information. Part 2 contains tutorial information to assist manufactures in complying with Part 1, as well as offering more detailed descriptions of usability engineering methods that can be applied more generally to medical devices that go beyond safety-related aspects of medical device user interfaces. It is recommended that only one of the series should be used in any one country. Superficial comparisons between the values used in the various countries may lead to erroneous conclusions if they are not based on common criteria: for example, there may be different expectations for the life of the cables, and in some countries design is based on maximum values of soil thermal resistivity, whereas in others average values are used. Also in this section is an outline of the information required from the purchaser for the selection of the appropriate type of cable.

For instance, with respect to the ambient temperature and soil thermal resistivity, the values are governed in various countries by different considerations. To find additional standards, please use the search bar above. It should be noted that one of the responsibilities of a technical committee is, wherever possible, to include or refer to requirements of basic safety publications in standards for equipment within its scope. The electrical equipment of vehicles operating international services in these countries shall be capable of withstanding this absolute maximal voltage for brief periods of up to 5 min. Available in English, French and Japanese. Such systems have found use in industry, business, entertainment, research, education, medicine and consumer products. Consequently, the requirements of this basic safety publication apply only if they are included, or are referred to in those standards.

Attention is drawn to the fact that the information in clause 4 is intended only as a guide for cable installation designers when data provided by a user is incomplete. Typically, laser products are used for demonstration of physical and optical phenomena, materials processing, data reading and storage, transmission and display of information, etc. The committee has decided that the contents of the base publication and its amendments 1 and 2 will remain unchanged until 2003. It bears the edition number 6. This standard further includes general rules for an alphanumeric system. It serves as a basis for agreements about the preparation of a structured documentation, primarily required for larger installations.

When one value only is indicated, it refers to three-wire systems and specifies the voltage between phases. The values indicated in parentheses should be considered as non-preferred values. It is recommended that in any one country only one value in the following groups should be used for the highest voltage for equipment: 123 kV-145 kV 245 kV-300 kV see table 5 -363 kV see table 5. The values indicated in the table above are the values agreed by the International Mixed Committee on Electric Traction Equipment C. . For undated references, the latest edition of the referenced document including any amendments applies.

At the time of publication, the edition indicated was valid. Use of the referenced publications is indispensable for the correct application of this publication. For the utilization voltage range, in addition to the voltage variations at the supply terminals, voltage drops may occur within the consumer's installations. A vertical line in the margin shows where the base publication has been modified by amendments 1 and 2. It is recommended that these values should not be used for new systems to be constructed in future. The lower values in the first and second columns are voltages to neutral and the higher values are voltages between phases. An enquiry into this subject has been carried out and a number of countries have replied.
