Automotive Glass Standards.

Customers at car shows and swap meets regularly ask two questions and whilst both questions are important, they are likely coming from different perspectives. “Does the glass supplied by Glass 4 Classics meet all Automotive Glass Standards and is it marked accordingly?  (yes I know, that is really two questions!). The other question is, “Can any old toughened glass, laminated glass or Perspex be used in car windows”.

The answer to these questions are: 

  • Customers of Glass 4 Classics will always receive glass that meets or exceeds Automotive Glass Standards and will be marked accordingly.

Can any old glass be used in the car?

  1. NO!
  2. There are national standards that must be complied with. i.e. there are laws that because of these standards tell you what you can and can’t use.
  3. The standards are there to ensure your kept as safe as possible when driving and to reduce injury because of an accident. These standards and the state laws that enforce them make sense.

There are those who may choose not to comply with these standards and look for ways around the laws that enforce them. This no different to those on our roads who choose to flaunt the road rules. Whilst they may get away with it, people are killed and maimed on our roads every day, because someone thought they knew better and decided to break those rules. Not running a red light, not overtaking across an unbroken line, not exceeding the speed limit are examples of laws that are there to keep us as safe as possible when we drive. Likewise, the rules and regulations relating to our car windscreens and windows (body glass) are there for our good.

This brief article from the Auto Glass Association. has been extracted to explain the standards the Automotive Glass industry must comply with, when supplying glass for your vehicle. .

“Auto glass such as windscreens and body glass used in Australia, whether it be original or replacement glass, must comply with the national standard cited as Australian Design Rule (ADR) 8/01- Safety Glazing Material 2005.”

The Department of Infrastructure and Transport is responsible for administrating this rule on behalf of the administrator of vehicle standards.

The function of this national standard is to specify the performance requirements of material used for external or internal glazing in vehicles to:

  • Ensure adequate visibility under normal operating conditions
  • Minimize obscuration when shattered
  • Reduce the likelihood of serious injury if a person comes in contact with any broken glazing material.

All material used for external and internal vehicle glazing must have properties at least equivalent to the requirements of one or more of the following standards.

  1. Australian and New Zealand Standard  – AS/NZS2080: 2006 ‘Safety Glass for Land Vehicles’.
  2. Economic Commission for Europe (ECE) R-43/00 ‘Uniform Provisions Concerning Approval Of Safety Glazing And Glazing Materials’ 
  3. British Standards Institution – BS AU178a: 1992 ‘Road Vehicle Safety Glass’.
  4. Japanese Industrial Standard – JIS R 3211: 1998 ‘Safety Glazing Materials for Road Vehicles’
  5. American National Standard – ANSI Z 26.1: 1996 ‘Safety Glazing Materials for Glazing Motor Vehicles and Motor Vehicle Equipment Operating on Land Highways – Safety Standard’. (U.S.A. Dept. Of Transport License)

How to tell if glass complies with these standards?

The ‘compliance mark’, also be known as a bug, logo or glass monogram is the secret to identifying compliant glass. Auto safety glass needs to have one to be legally compliant. 

1. Below is a typical auto glass bug of an OEM glass. This is confirmed by the DOT number 617. Each auto glass plant will be assigned a permanent DOT code number by the American NHTSA (National Highway Traffic Safety Administration) in accordance with Federal Motor Vehicle Safety Standards, US, FMVSS 205, Glazing Materials. The DOT number enables the identification of the glass manufacturer and confirms the glass meets the US standard. In doing so, it also complies with Vehicle Standard-Australian Design Rule 8/01 – Safety Glazing Material 2005. Auto glass plants must renew their DOT compliance certificate with the US Automotive Manufacturers Equipment Compliance Agency (AMECA) every four years.

*Note that AS/NZS 2080:2006 is only one of the approved standards that specified in Australian Design Rule 8/01. The following is an example of a glass using the AS/NZS 2080:2006 standard.
