The consumer properties of goods represent their quality. They determine the suitability of the product for specific human needs. Consumer properties are manifested in the process of using the product.
Functions, reliability, ergonomics
Functional properties reflect the purpose of the product. These include the perfection of the main function, versatility, and the perfection of the auxiliary functions. The main purpose of each product is different. The quality of performance is determined by the parameters, composition, type of raw materials. Versatility - a range of conditions and possibilities of intended use. Auxiliary functions expand capabilities and improve usability.
Reliability properties: the ability to perform functions in certain modes and conditions without deteriorating performance. This includes durability, reliability, repairability, and preservation. If these indicators change, they talk about wear. Durability - the ability to maintain performance over a service life or shelf life. Reliability - the ability to work for a while without failures. Preservation - the ability to perform the specified functions after storage and transportation. Suitability for repair - the suitability of a product for maintenance.
Ergonomic properties - ease of use. The product must match the size and shape of the human body. The physiological properties of the product must satisfy human needs. They affect the functioning of the body. Non-food products also have hygienic properties: maintaining normal humidity, permeability, electrification, contamination, etc. The properties of the product must correspond to the psychophysiological capabilities of a person, as well as his skills, thinking and perception.
Aesthetic and ecological properties
Aesthetic properties - the ability of a product to satisfy the need for aesthetic pleasure. It must reflect the accepted norms of culture and ideas about aesthetics, be original. An important criterion for a number of products is compliance with style and fashion. The product should be a complete composition with interconnected elements. The shape and design of the product must correspond to its purpose, which speaks of aesthetic feasibility. The aesthetic properties also include the perfection of product performance.
Environmental properties - the ability to influence the environment. Such influence can be carried out during production, storage, operation, disposal. This includes various indicators and estimates of probability. The environmental impact of goods can include the release of toxic substances, pollution of the planet's resources, etc.
