Comparative test of mattresses according to new and old Croatian standards
Research subject and fields:
As Croatia gets closer to the European Union its standard system. The aim of this paper is to compare the methods and results of testing and values of hardness and height loss of mattresses in accordance with the old HRN D.E2.103: 1985; HRN D.E8.228: 1982 Croatian standards and the new HRN EN 1957: 2001 Croatian standard. The results of research show the existence of significant differences between the old and new standards for mattress quality testing and consequently it is very hard to compare the results of testing as well as of hardness and firmness. Nevertheless research results show that values of height loss according to the European standard is significantly lower than according to the old Croatian standard. Results of durability testing performed in accordance with the European standard meet a high quality level - QII in the old Croatian standard. The GRPESV model shows the highest values of height loss according to both standards.
