AS 60238:2022

AS 60238, 2nd, 2022 – Edison screw lampholders (IEC 60238:2016 (ED. 9.2) MOD)

This Standard was prepared by the Australian members of the Joint Standards Australia/Standards New Zealand Committee, EL-041, Lamps and Related Equipment, to supersede AS 60238:2015, Edison screw lampholders (IEC 60238, Ed. 8.2 (2011) MOD).

AS 60238:2015 will also remain current for three years after the date of publication of this document and after this time it will be superseded by AS 60238:2022. Regulatory authorities that reference this document in regulation may apply these requirements at a different time. Users of this document should consult with these authorities to confirm their requirements.

This document will also operate in parallel with AS/NZS 3140, Approval and test specification—Edison
screw lampholders. While this document (AS 60238:2022) and AS/NZS 3140 operate in parallel, they are separate standalone documents and the chosen Standard (i.e. AS 60238 or AS/NZS 3140) is applied in its entirety. The interchanging of requirements from each Standard is not permitted to determine overall compliance of an Edison screw lampholder, except when either Standard specifically references the other Standard’s requirements.

The objective of this document is to specify particular requirements for Edison screw lampholders used in general purpose lighting.
The essential safety requirements of AS/NZS 3820, Essential safety requirements for electrical equipment, that could be applicable to Edison screw lampholders are covered by this document, taken in conjunction with any other relevant requirements affecting safety.
The major changes in this edition are as follows:

(a) New definitions have been added.
(b) Creepage and clearance — Tables 13a, 13b and 14 have been modified.
(c) The calculation method in Clause 21 for ball pressure has been deleted.
This document is an adoption with national modifications and has been reproduced from the red line version of IEC 60238:2016+AMD1:2017+AMD2:2020 CSV, Edison screw lampholders, and has been varied as indicated to take account of Australian conditions. The variations listed in Appendix ZZ address issues including resistance to flame and ignition. Appendix ZZ has been added at the end of the source text. The variations described in Appendix ZZ form the Australian variations for the purpose of the CB Scheme for recognition of testing to standards for safety of electrical equipment (the CB Scheme).

This document is structured as follows:

(i) Preface.

(ii) IEC 60238:2016+AMD1:2017+AMD2:2020 CSV (unedited red line version from the contents page to the final clause of the source document)

(iii) Appendix ZZ — Australian variations to the source document.

As this document has been reproduced from an International Standard, the following applies:
(A) In the source text “this International Standard” should read “this document”.
(B) A full point substitutes for a comma when referring to a decimal marker.
