Standards and regulations
An overview of the Australian and overseas standards relating to child restraints and accessories used by children with disabilities and medical conditions
Introduction
Australian and overseas standards/regulations provide requirements to support the design, safety and use of child restraint systems in motor vehicles.
However, these standards/regulations differ, particularly for child restraint systems designed for children with disabilities and medical conditions.
Child restraints sold through shopfronts in Australia (Australian standard car seats) comply with the Australian standard, whereas special purpose car seats comply with overseas standards/regulations. This is because, unlike the Australian standard for child restraints, overseas standards and regulations provide safety and performance requirements for special purpose car seats.
Australian standards
There are three key Australian standards and a new one being developed that relate to transporting children with disabilities and medical conditions in motor vehicles. An exciting development to the Australian standard for child restraints is the inclusion of requirements for variations for child restraint systems for children with disabilities and medical conditions. In addition a new standard is considering requirements for harnesses/vests.
- Australian/New Zealand Standard 1754 Child restraint systems for use in motor vehicles (AS/NZS 1754)
- Australian Standard 8005 Accessories for child restraints for use in motor vehicles
- New: Australian Standard 5384 Accessories for seat belts for use in motor vehicles which is considering harnesses and vests.
- Australian/New Zealand Standard Restraint of children with disabilities, or medical conditions, in motor vehicles (AS/NZS 4370)
Overseas standards and regulations
There are four key overseas standards/regulations which all special purpose car seats, and some harnesses/vests comply with.
- United Nations Economic Commission for Europe Regulation No 44 Uniform provisions concerning the approval of restraining devices for child occupants of power- driven vehicles (ECE r44)
- United Nations Economic Commission for Europe Regulation No 129 Uniform provisions concerning the approval of enhanced Child Restraint Systems used on board of motor vehicles (ECE r129)
- United States Federal Motor Vehicle Safety Standard 213 Child restraint systems (FMVSS 213)
- Canadian Motor Vehicle Safety Standard 213 Child restraint systems (CMVSS 213)
Key differences
There are many differences in the technical requirements of each standard and regulation.
Key differences include:
Dynamic testing
The Australian standard has more dynamic testing requirements, including frontal, side, rear (for some restraints), and inverted for baby restraints to test for occupant ejection. It also tests to a greater force than overseas standards.
Weight vs height
Australian standard car seats use shoulder height markers and approximate age to guide use, similar to the ECE r129. Whereas ECE r44 only uses occupant weight (up to 36 kg). In contrast, the US (FMVSS) and Canadian (CMVSS) have no weight requirements, therefore special purpose car seats from these locations permit higher occupant weight.
Lifespan
US (FMVSS) and Canadian (CMVSS) child restraints generally have a 6 year life, whereas Australian Standard restraints have about 10 years, due to the mandatory use of UV and thermal stabilizers.
Side impact testing
Side impact protection is a key feature of Australian standard car seats. This is why they have big side wings that surround the child’s head area. Until recently Australia had the only standard in the world requiring side impact testing. However in recent times it has been introduced in the ECE r129, and has been proposed for the US (FMVSS) and Canadian (CMVSS) standards.
This means we are likely to see improved side impact protection features for some special purpose car seats in the future.
Requirements
The Australian standard does not provide safety and performance requirements for special purpose car seats.
In comparison, overseas standards and regulations provide requirements for special purpose car seats, which means all products available in Australia comply with overseas standards or regulations.
European regulations
The ECE r44 was first adopted in the 1990s, with the new ECE r129 (also known as “i-Size”) introduced in July 2013. ECE r129 introduces additional safety benefits and will eventually replace ECE r44. At the moment both regulations are able to be used.
The Australian Safety Assessment Program is currently sled-crash testing and reviewing a special purpose car seat that complies with ECE r129. This will be the first restraint available in Australia that complies with this regulation. Over time we expect to see more special purpose car seats available that comply with ECE r129.
Key differences between the two regulations are:
Regulation No. 44 | Regulation No. 129 |
Classification based on child’s weight | Classification based on child’s height (in cm) |
Categorised by groups (Group 0+, 1,2,3) | No groups |
Child can be forward-facing from 9 kg | Child must rear face to a minimum of 15 months |
Can be used for seatbelt and ISOFIX seats | Can only be used for ISOFIX |
Rear and front impact testing | Rear, front and side impact testing |
P dummy used in crash tests with 4 sensors | Q dummy used in crash tests with 32 sensors |

I heard there is a prescribing standard, now I know what it is and I am so grateful MACA's website brings this to life!
