CERTIFICATION
When
purchasing a life jacket approved by the Brazilian Navy, require the
presentation of the certificate and its accessories (Lamp
and reflective tape). - The approval has a validity period of 5 years.
See the website of the Navy, DPC, approved materials www.dpc.mar.mil.br
The lifejackets ATIVA 5 and ATIVA 4 were tested, approved and certified
by the Brazilian Navy by the Board of Ports and Coasts,
as "NORMAN 05/2000". Passed through scientific tests in
real situations of danger (of fabric traction, fire, buoyancy,
mechanics resistance of the vest, jumping performance at 10 meters
high, etc). These tests were "in situ" overseen by an marine
engineer official of Brazilian Navy and implemented by institutions
of public recognition such as:
• IPT (Institute for Technological Research at the University
of São Paulo)
• Francisco Matarazzo School of Education and Technology for
Textile Industry (National Service Industry)
• Port Authority of Santa Catarina (Brazilian Navy)
Description of tests applied on 6 samples (6 jackets):
Test characteristics of the prototype -
The evaluation of the prototype of the vest made by naval engineers
of IPT and the Navy.
- Features approved for use.
Test Buoyancy
Immersion in water for 24 hours to detect the loss of buoyancy in this
period. There was no loss of buoyancy.
Test mechanics resistance of jackets
the children's jackets, medium and large were tractioned in a horizontal
position for more than an hour with up to 320 kg and hung on
cross position with 90 kg for more than 30 minutes. There were no damage
or deformation.
Traction
tests applied on tissues used for the manufacture of lifejackets
Developed by the Senai School Francisco Matarazzo and supervised by
IPT. Ten samples of four kinds of tissues were tractioned after submerged
in salt water. Tissues resisted the equivalent of a traction of the
approximately 150Kg and the puller tapes (closing) resisted 500 kg
Testing the performance of jackets
Six people wearing each size of life vests, (including infant up to
35 kg) jumped six times into water from a base, 10 meters high.
This test was conducted in collaboration with the Olympic Diving Team
from "Club Pinheiros" at São Paulo and supervised "in
loco" by officers of the Brazilian Navy. There was no occurrence
of failures in life jackets and discomfort to athletes.
The vest were easily dressed in less than 30 seconds.
Test performance on fire
The vest is subjected to a flame of 50 cm in height, whose fuel is pure
gasoline, simulating a situation where the user had
to pass through the fire for 2 seconds. The damage did not alter the
buoyancy of the vest within 24 hours after.
(test required to collect the Class IV).
