One of the main criteria of customer satisfaction with purchased goods is to ensure that the products are able to fulfil their purpose and that an individual's life, health and property are not jeopardised by their use. A customer is considered to be the weakest link of the market chain as he has only a limited means of power and authority to impose and defend his needs and interests. The state can help by creating a legislative framework to provide rules and regulations to guarantee and protect customer's interests effectively. This area of considerations is also taken into account in research conducted by the specialists in the field of wood science and industry.
