An Inside Look: Drop Testing Helmets to Australian & International Standards & Design Rules

 

Motorcyclists & Motorsport enthusiasts, buckle up for a compelling journey that unveils the crucial link between helmet safety and your passion for adrenaline. We shed light on the specific risks you face, and the devastating consequences of Traumatic Brain Injuries (TBIs), & present an innovative solution to fortify your protection.

 

Welcome to The Helmet Doctors, where we strive to empower you with the knowledge and tools to ensure a safe and exhilarating ride/drive every time knowing your helmet’s structural integrity is in optimal condition.

Below and the following stories we will brief you on the areas:

 

  • The Hidden Dangers,
  • The Unseen Perils of TBIs & Death,
  • How to Empower Prevention through Preventative Measures & Helmet Laser Scanning,
  • The Simplicity of Taking Action to Enhance Your Safety,
  • How you can become a Beacon of Hope for others,
  • How Joining our Passion for Advancements in Helmet Safety Can Save Lives and How It Just Might Be Yours That Counts.

 

But now let’s look at …

 

An Inside Look: Drop Testing Helmets to Australian 

& International Standards & Design Rules

 

Ensuring our scientific understanding of helmet inspections, we investigated, dissected, and drop-tested various helmets with the assistance of The University of Queensland and Crashlab- the Centre for Road Safety, Transport Department of New South Wales.

Cashlab testing facilities are world-class, to Australian Standards and Australian Design Rules. 

Crashlab maintains compressive National Association of Testing Authorities, Australian & International accreditation for compliance and helmet testing.

Physical inspections, scientific measurements & many before & after (drop test) images were taken, using the Non-Destructive Laser technique of Holographic Interferometry providing an inside look and evidence of our Laser Scanning technique.

 

So … What is the Problem?

Upon impact, a motorcycle helmet’s first line of defense is for the shell to flex and dissipate 34% of the impact energy, then ultimately absorb the rest through the EPS foam. Nowadays, helmets do this so well that they don’t appear to be impacted at all.

 

Internal Damage to the EPS foam

In the above example, the danger lies when the helmet has taken an impact but there is no evidence on the outside of the shell or inside of the EPS foam.

Therefore, the helmet has done its intended job and you have avoided a possible TBI or even premature death.

Below is a short video showing “An Inside Look” at damaged EPS foam.

 

In this case, we only concern ourselves with the likes of a Flat Anvil Impact and a Hemispherical (Hemi) Anvil Impact. This is because the spike test would result in a piercing of the outer shell, which would render the helmet damaged because it would be visible to the naked eye.

 

All impacts to the EPS below were to Australian Standards of AS/NZS1698.

  • 2x Flat Anvil impact at a drop height of 1830mm.
  • 2x Hemispherical impacts at a drop height of 1385mm.

 

As we know the outer shell of the helmet is more effective at dissipating shock than the EPS interior. 

The integrity of the EPS liner becomes immaterial if the outer shell has been compromised, ie the helmet then becomes no longer fit for use.

 

Generally speaking, there’s a possibility the integrity of the EPS liner could become compromised from the inside, but with normal use, the liner should generally outlast the outer shell. Upon visual inspection of the inside EPS liner, the degradation of the EPS liner will be apparent if it is present. Most helmet manufacturers coat the white EPS with a material that resembles black paint. When inspecting the inner liner, if you see white speckling, cracking, or splitting of the EPS foam, this implies the liner has deteriorated or suffered an impact that will automatically render the helmet damaged.
