4 The meaning of "strength" and "resistance"

An industrial floor not only has to be cheap. It must also stand up to numerous different demands. It must be strong.

Already at my inaugural lecture for the 2^nd International Colloquium "Industrial Floors '91" I dealt with the multi-faceted word "resistance" which may be considered as largely synonymous with the word "strength". I repeat here what I said 10 years ago:

Fork-lift truck	fork-lift truck	resistent
Pallet truck	pallet truck	resistent
Small metal wheels	metal wheel	resistent
Containers with metal feet	metal foot	resistent
Loads up to 1,500 kg and more	bending tension	resistent
Rolling barrels	impact	resistent
Falling metal parts	damage	resistent
8 m stack height	pressure	resistent
Spark formation	spark	resistent
Explosive gas and powders	explosion	resistent
Aggressive acids	chemical	resistent
Sulphur compounds	sulphur	resistent
Groundwater protection	liquid	resistent
Surface	scratch	resistent
Food production	microbe	resistent
Mould	mould	resistent
Wet areas	water	resistent
