Penelitian korelasi pengaruh cuaca dengan alat weather 0 meter dan dengan cuata langsung udara terbuka terhadap kekuatan bengkuk sol karet cetak

The aim of this research was to obtain the correlation weathering exposure by Weathering 0 Meter Apparatus (in door weathering test) and directly exposure to the out door weather (out door weather test) on the flexing of moulding rubber sole. Sample used in this research were 216 by weather 0 Meter Apparatus and 147 by directly exposure to the out door weather. Testing for the flexing on rubber and Plastic Physical And Chemist Laboratory, IRDLAI, Yogyakarta, by reference SNI.0778-1989-A. The results of physical tests were analysed using T test. The Correlation for testing of moulding rubber sole specimen exposes by Weather 0 Meter (in door) for one hour giving similar change in the out door weather as long as 12,8 hours.
