Standards, test methods and code guidance
The PLC develops and maintains the technical framework that underpins reliable, compliant photoluminescent safety systems across Australasia.
SA TS 5367:2021
On 22 October 2021, Standards Australia released Technical Specification SA TS 5367:2021, Hybrid photoluminescent signage — Product specification, installation and operation.
The specification is designed to sit alongside the NCC documentation as an alternative deemed-to-satisfy solution, giving practitioners an objective, detailed toolkit for achieving best practice.
The 25-page document relates only to Hybrid PL Exit Signage — PL signs fitted with their own adjacent LED luminaires to keep panels charged. It is hoped a similar specification will follow for Passive PL Exit Signage, which is charged solely by surrounding light.

Products must be tested against these PLC methods to demonstrate the longevity, durability and luminance required for safe egress.
HTC (High Temperature Curing) Test
A manufacturing process that ensures photoluminescent products achieve maximum longevity and durability. Products must be tested against the HTC Test Method to qualify.

Path markings in a Safe Movement System must provide sufficient luminance. Activation charging exposes products to a D65, 5000 lux light source for 60 minutes.

High Luminance systems must sustain luminance long enough for safe evacuation. Charging exposes products to 1 ft-candle (11 lux) at 4000–4500K for 60 minutes.

Part E4 of the National Construction Code (NCC 2016), released in May 2016, was retitled "Visibility in an Emergency, Exit Signs, and Warning Systems". The objective of the Australian Building Codes Board (ABCB) was to encourage innovation through a performance-based design approach.
The ABCB replaced the term "Alternative Solution" with "Performance Solution" to clarify that Performance Requirements are the mandatory components of the code — a Performance Solution satisfies the code, and the deemed-to-satisfy prescription is just one of many valid approaches.
This opened opportunities for designers to deliver cost-effective, sustainable performance solutions, and endorsed photoluminescent products as a viable alternative in emergency evacuation systems.
In 2014, provisions were made in the NCC to allow PL technology as an alternative to internally or externally illuminated exit signs. However, there was still no Australian or New Zealand Standard specific to PL exit signs, nor requirements for their routine inspection and maintenance.
With no clear guidelines and the risk of failure in signs not properly maintained, the market favoured electrical signs and hindered PL adoption. After extensive industry consultation, in 2019 the PLC developed and ratified three standards specific to PL exit signs — closing the gap and giving specifiers a compliant path forward.
