The quality of use outdoor decking for inside stair treads can be detected by them, if if there is no perfect evaluation system and detection methods, so as not to be able to carry out a full range of product quality assessment. Wood product standards following aspects should be further improved, as follows:
1) improve the detection of outdoor composite decking, by analyzing the sources of raw materials and production characteristics of wood products, wood products may exist for toxic and hazardous substances and their hazards assessment and research to develop a reasonable and effective detection method limited requirements.
2) improve the aging test methods and performance evaluation system, based on the use of solid fence and maryland use and the environment, require different aging conditions and evaluation methods in the development of standards, such as resistance to UV aging, salt spray aging, high-temperature aging, low temperature and aging; aging results of the evaluation method, not only the bending strength and mass loss rate were evaluated after aging, but also focus on other changes in the mechanical properties after aging, as well as long-term use of the product in the process of change, such as the impact of food provision mouth creep Variable performance evaluation and the like.
3) Develop wood products overall structural performance evaluation methods and standards, wood products as a whole, its performance can be assessed only by the part of the performance is good or bad.
