Railway Track Material Part 2: Fishplates
Preface
This standard was prepared by the Railway Track Material Part 2: Fishplates Development Group,
overseen by the RISSB Infrastructure Standing Committee.
Objective
The objective of this Standard is to provide purchasers and suppliers, including owners,
operators, designers and manufacturers of railway rail with requirements for fishplates for use
with rails in accordance with AS 1085.1 in railway track.
Changes to the previous edition are as follows:
(a) Change of title of the AS 1085 series (previously Railway permanent way
material).
(b) The referenced documents list has been revised.
(c) Reference to the withdrawn Standards AS 1213 and K1 have been removed.
(d) The most recent version of the informative Appendix ‘Means of demonstrating
compliance with this Standard’ has been included.
Compliance
There are four types of provisions contained within Australian Standards developed by RISSB:
(a) Requirements.
(b) Recommendations.
(c) Permissions.
(d) Constraints.
Requirements – it is mandatory to follow all requirements to claim full compliance with the Standard.
Requirements are identified within the text by the term ‘shall’.
Recommendations – do not mention or exclude other possibilities but do offer the one that is preferred.
Recommendations are identified within the text by the term ‘should’.
Recommendations recognize that there could be limitations to the universal application of the control,
i.e. the identified control is not able to be applied or other controls are more appropriate or better.
Permissions – conveys consent by providing an allowable option. Permissions are identified within the
text by the term ‘may’.
Constraints – provided by an external source such as legislation. Constraints are identified within the
text by the term ‘must’.
For compliance purposes, where a recommended control is not applied as written in the standard it
could be incumbent on the adopter of the standard to demonstrate their actual method of controlling
the risk as part of their WHS or Rail Safety National Law obligations. Similarly, it could also be incumbent
on an adopter of the standard to demonstrate their method of controlling the risk to contracting entities
or interfacing organisations where the risk may be shared.
Appendices in RISSB Standards may be designated either “normative” or “informative”. A "normative"
appendix is an integral part of a Standard and compliance with it is a requirement, whereas an
"informative" appendix is only for information and guidance.

Section 2 Designation
Fishplates shall be designated by the number of this Australian Standard and the nominal rail size.
Example: Fishplate in accordance with AS 1085.2 for 50 kg rail.
Section 4 Brands
Each fishplate shall be branded with figures denoting the mass per metre of rails for which it is intended,
and a mark to identify the manufacturer and the year in which it was rolled or forged, e.g., 50XXX03.
The letters and figures shall be rolled or forged on the outside surface of the fishplate and shall be raised
a minimum of 0.5 mm from the plane surface of the fishplate.
The year of manufacture shall be used for the purpose of identification only. The year of manufacture
should not be used as a basis for rejection of the fishplates.
Manufacturers making a statement of compliance with this Australian Standard on a product, packaging,
or promotional material related to that product are advised to ensure that such compliance is capable of
being verified.
5.1 General
The chemical composition shall be determined by cast analysis.
Sampling, preparation and testing shall be by any procedures that are not less accurate than those in
AS/NZS 1050.

5.3 Composition
The cast analysis of the steel as per Clause 5.2 shall conform to the limits of chemical composition given
in Table 5-1.
Section 7 Finish
Fishplates shall be free from defects that are detrimental to their end use. Localized areas of
deformation caused by shearing or punching and conforming to the tolerance limits given in Table 11-1

The section shall conform to the appropriate profile given in Appendix B.
A variation of 2.0 mm horizontally outwards shall be permitted if a fishplate template is placed on the
rolled bar or forging.
The section shall not vary horizontally outwards by more than 2.0 mm from the nominal position.
8.2 Dimensions
Fishplates shall conform to the dimensions indicated for the appropriate profile given in Appendix B,

Section 12 Retests
If either of the test pieces fail to comply with the specified requirements, two further samples shall be
taken and tested in accordance with this Standard.
If the test pieces from both of these further samples pass, the parcel shall be deemed to comply with
this Standard.
If either of the additional test pieces fails, the parcel shall be deemed not to comply with this Standard.
