CAN/CSA-E61965:04 (R2023)

Description

CSA Preface This is the second edition of CAN/CSA-E61965, Mechanical safety of cathode ray tubes , which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61965 (second edition, 2003-07). It supersedes the previous edition, published in 2001 as CAN/CSA-E61965 (adopted IEC 61965:2000). For brevity, this Standard will be referred to as “CAN/CSA-E61965” throughout. Underwriters Laboratories (UL) is also publishing this International Standard, under the designation UL 61965. Previously, CSA Group and UL published a binational standard, CAN/CSA-C22.2 No. 228-92/ UL 1418, Cathode Ray Tubes. To maintain harmonized status on the International Standard, revisions will be coordinated by CSA Group and UL. This adopted International Standard replaces binational standard CAN/CSA-C22.2 No. 228-92/UL 1418, which is being withdrawn. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on International Standards, under the jurisdiction of the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This International Standard is applicable to cathode ray tubes and cathode ray tube assemblies (hereinafter referred to as CRTs) which are intended for use as components in apparatus and which have integral protection with respect to the effects of implosion.  These requirements apply to CRTs intended for use in apparatus including electrical and electronic measuring and testing equipment, information technology equipment, medical equipment, telephone equipment, television equipment and other similar electronic apparatus.  This Standard is intended to apply only to those CRTs in which the face of the CRT forms part of the enclosure for the apparatus. The test methods do not apply to CRTs which are protected by separate safety screens.  A CRT covered by this standard is intended to be installed in an enclosure designed both to protect the rear of the CRT against mechanical or other damage under normal conditions of operation and to protect the user against particles expelled in a backwards direction from the CRT face in the event of implosion.  This Standard contains requirements for CRTs of 76 mm diagonal and larger that incorporate implosion protection systems providing protection against the hazards of particles expelled forwards beyond the face. There is no intended protection against particles expelled in other directions.  Compliance is tested by subjecting CRTs to the test procedures and criteria, which are given in Clauses 8 (large CRTs), 9 (small CRTs) and 10 (CRTs with protective film) of this standard. The definitions of large and small CRTs are given in Clause 3.  NOTE This set of requirements replaces the current requirements for the mechanical safety of cathode ray tubes (CRTs) as described in IEC 60065 (Clause 18), which will be modified accordingly.
