Guide to Nemeth Javelin Ratings
2011-11-25 14:59 by Administrator
The following is a short description of how Nemeth Javelins are calibrated and rated.
A javelin's flight characteristics depend on many factors - the javelin's shape, its tip design, its flexibility, the position of the gravitation point, just to name a few. All these qualities are important and factor in during the flight. This is why we made the following type of classification of our products as follows:
According to IAAF rules
There
are 800g, 600g, 700g and 500g IAAF approved javelins and 400g javelins for the
veteran age group.
Our competition
javelins have three classes in the weight groups 600g & 800g : Standard
(School)
Club
Classic
For
the 500g & 700g weight groups there are two classes:
Special
competition
Universal
competition
The
names suggest what kind of thrower groups they are specifically designed for.
Standard (in some country named as School) javelins
Within
the classes we developed our (metric) distance rating system. This is how we
define the quality of the javelins for example:
Standard 600g 40m,
Standard 600g 50m,
Standard 600g 60m,
Standard 600g 70m,
The
shape of the shaft of the Standard 600g 70m javelin is superior to the 40m one.
The higher class Club javelins have a new
aerodynamic blunt head and the distances ratings are extending from Club 600g 70m
Club 600g 75m
The
shape of the shaft of the Club 600g 70m javelin is superior to the Standard
600g 70m and it has an aerodynamic blunt head on the shaft.
The Classic series is built with an even more aerodynamic
bulky head with the optimum aerodynamic shape of the shaft
Classic 600g 75m
Classic 600g 80m
Classic 600g 85m
Classic 600g 85m AL-Composite
The
difference between the 75m and 85m javelin is the accuracy of the measurements
of the javelins defined by our production and design.
Classic
600g 85m AL-Composite received a carbon fiber coating in addition to increase
stiffness when required while decreasing the vibration of the javelin.
Each
javelin class has a unique tip and head design. Our higher distance rated
javelins have bulkier head and tips with great front lift properties.
It
is a good rule of thumb that with a higher class, higher DR javelin better
results can be achieved, within the abilities of the athlete.
Nemeth
javelins are made of a special aluminum alloy that gives the flexibility of
aluminum with the stiffness of steel or carbon, yielding a javelin with superb
flight characteristics.
Our
Composite Al-Carbon javelins are made of an aluminum-carbon composite, which gives a very low
flexibility javelin, which is perfect for the most skilled throwers!
