Desarrollo de los equipos de prueba para la implementación de ensayos de resistencia a factores físicos aplicados a vidrios de seguridad según las normas NTE INEN 1722, 1724, 1726 y 1731.

Abstract

It has developed a system composed of several tests of resistance to environmental and visual physical factors according to the requirements of the NTE INEN 1669, 1722, 1724, 1726, and 1731 standards in order to verify the minimum requirements to be met laminated safety glasses and temperature (windshield, rear windows, side windows, etc.) to be installed in motor passenger or cargo being manufactured in the country. Physical factors to be tested are: fragmentation, impact, high temperature and humidity, which are described below for the fragmentation test consists of a hammer, table, balance, which is the break the samples, counting and weighing fragments bigger. The impact test (dummy) consists of a telescopic tower, dummy and sample holder, this in turn is to raise 1.5 m drop the dummy and without momentum. The high temperature test consists of a container, thermometer, stirrer, it is to maintain the specimens immersed for 2 hours in boiling water. The humidity test consists of a container, electrical resistors stirrer is immersed in water for 2 weeks specimens maintaining the water temperature between 49 and 54 ºC. The tests were acceptable, confirming product quality seal for those who have INEN and the nonconformity of those who do not have this requirement. Finally a documentary system according to the requirements established in the rules to facilitate the implementation and trials register was developed.
