The Use of Resistant Glass in Special Agricultural Machinery and the Logistic Support Depending on Operating Temperatures

The paper is concerned with quality assessment of bullet‑resistant glass in relation to ambient temperatures. The measurement results provided below may be drawn on in the field of logistics when transport, special as well as special agricultural machinery are operated at fluctuating temperatures. In the paper, data from shooting tests, monitoring the projectile velocity, penetration through the glass and projectile fragmentation at various ambient temperatures, is presented. For perfect protection of agricultural machine operators not only the bullet‑resistance of glass panels, but also their further use in work is of great importance. Hence, emphasis is put on active safety of these machinery, where a perfect transparency of the bullet‑resistant panels is one of crucial factor. In the paper, the extent of damaged areas is compared; these are divided into three zones according to significantly differing temperatures. The paper results may have influence on agricultural machinery in thermally extreme areas.
