Gapless Metal Oxide Surge Arresters for Alternating Current Systems
1. Scope
1.1 This Standard applies only to gapless metal oxide surge arresters of separate mounting or those supplied integrally with other equipment. The surge arresters are designed to limit voltage surges in 50 or 60 Hz alternating current power circuits by passing surge discharge current without causing power interruption.
1.2 The values given in SI (metric) units are the standard…
1. SCOPe
1.1 This standard applies to golden kraft envelope paper for face and back
letterpress and offset (lithographic) printing of covers for tablets,
separators and envelopes. Envelopes made with this paper are intended for
general use and also for repeated use in interdepartmental transmission of
papers.
1. SCOPe
1.1 This standard applies to kraft paper, standard finish, suitable for use in
file folders and for face and back letterpress and offset (lithographic)
printing of file folders, covers of form books, scrap books, etc. File folders
made from this paper are intended for repeated use in the filing and retrieval
of documents.
1. Scope
1.1 This Standard specifies a set of technical requirements and test methods for solar collectors and covers component materials, materials performance, operating performance, and marking requirements.
1.2 This Standard applies to solar collectors used for conver ting solar radiation into thermal energy. It covers only collectors with an aperture area of not less than 0.5 m²…
Codes for the Representation of Currencies and Funds
This National Standard of Canada is equivalent to International
Standard ISO 4217-1987. It provides the structure for a three-
letter alphabetic code and an equivalent three-digit numeric code
for the representation of currencies and funds. For those
currencies having minor units, it also shows the decimal
relationship between such units and the currency itself.
Wind Energy Conversion Systems (WECS)-Safety, Design, and Operation Criteria
1. Scope
1.1 This Standard specifies requirements for the safety of wind energy conversion systems, including design and operation under specified environmental conditions.
1.2 This Standard is concerned with all subsystems of WECS, including protection mechanisms, supporting structures, and foundations.
1.3 This Standard is concerned with the components and materials supplied by the…
Methods of measurement for radio equipment used in the mobile services. Part 5: Receivers employing ...
Deals with the definitions, the conditions and the methods of measurement used to ascertain the performance of receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using single-sideband amplitude modulation. The standard is intended to be used in conjunction with IEC 60489-1.
Methods of measurement for radio equipment used in the mobile services. Part 6: Selective-calling an...
Refers specially to mobile radio receivers having audio-frequency
band-widths generally not exceeding 10kHz for the reception of
voice and other types of signals, using:
a) angle (Type G or F: phase or frequency) modulation, or
b) double-sideband amplitude (Type A) modulation with full carrier,
c) or single-sideband amplitude (Type H, J or R) modulation with
full, reduced or suppressed carrier.…
