The Hyper Zero 1 wheel is tested and conforms to JWL standards.

JWL stands for 'Japan Light Alloy Wheel'.

The Japanese Ministry of Land, Infrastructure and Transport requires that aluminium wheels for passenger cars sold in Japan bear the JWL mark.

It is a safety standard required in Japan for Alloy wheels made for Passenger Cars.

VIA is the 'Vehicle Inspection Association'.

The VIA are a third party organisation whom verify whether a product meets the requirements prescribed by the JWL standard.

There are three main requirements for the JWL standards, the first being 'Drum endurance testing'

The purpose of this test is to check wheel rim strength & durability.

A wheel and tyre are placed onto the test apparatus, the assembly is run with radial stress added to simulate the vehicle weight.

After 500,000 cycles the wheel is inspected for and cracks, damage or deformation etc.( Hyper Zero-1 are tested to 600,000)

The second is the 'Rotary bending Test'.

JWL standards state that the wheel must endure  100,000 'cycles' to pass this part of the test, checks are made after on the actual wheel disk rather than the rim or drum.

The spoke and hub of the 'face' of the disk are inspected and the strength of the design and manufacture are tested during this section.

The wheels are placed on the test equipment and weight is placed onto the disk or face of the wheel, after 100,000 'cycles' the wheel is inspected for any bending, cracks or deformation.

The final part of the testing is impact testing.

So far the wheels have been run as they would have on a car, they have been placed on their backs and stress added to the disc face, if they are still surviving by that stage the impact testing begins.

JWL state that a wheel must be able to endure an impact at 13 degrees of 594kg.

The main purpose of this test is to check the strength between the rim & the disc cross section.

The area where the spokes meet the rim is a very important structural area and is subject to massive amount of stress, strength here is paramount to a good safe wheel.

The wheel, complete with tyre is placed in a machine which holds it at 13 degrees, a weight is dropped onto the outer edge of the rim/tyre to simulate hard impact like that which would be endured during a crash or hitting a kerb for example.

The wheel is inspected again after this impact to check for cracks, leaks etc.

After these tests are made and a pass is given the wheel is given the JWL authorisation and manufacture begins.

The manufacturer of the Hyper Zero 1 is a member of JAWA (Japan Light Alloy Wheel Association).

JAWA  is an organisation made up of various wheel companies and carries out research and technical studies concerning the manufacture, marketing and distribution of automotive light alloy wheels.

These activities also include market and technical research aimed at developing new demand for industry products plus many other related activities.
