Abstract:
Product quality indicators and evaluation methods. The indicator of
product quality means the quantitative description of one or more properties of the
product, its application to specific conditions of its creation and use or consumption.
They must meet the basic requirements of stability of quality indicators, help to
increase production efficiency on a planned basis, taking into account scientific and
technical achievements, ability to meet certain needs according to specific tasks.
Functional indicators describe the properties of the product, determine their main tasks,
determine the field of application of the product.
Keywords:
Product, quality, indicators, importance, tests, production.
Composition and structure indicators represent the amount of chemical elements
or group structures in the product [1]. The composition and structure indicators include
the mass fractions of the structural components of steel, the concentration of various
components in acids, the mass fraction of sulfur and ash in coke, the mass fractions of
sugar and salts in food and other products. Raw materials, materials, fuel and electricity
saving indicators describe the product's properties and represent its technical
improvement level or the standard of raw materials, materials, fuel and electricity
consumed by them.Many quality indicators of the product are their functions and
parameters [2]. However, in most cases this relationship is difficult to understand
adequately. The concepts of "symptom", "parameter" and "quality indicators" are
interrelated. Describing the complex nature of products, it is called the functional
ability of the product to fulfill its needs, purpose and tasks assigned to it. A complex
property describing the artistic expression of the product, the correctness of the form,
the integrity of the composition is called the aesthetics of the product. The safety of the
product is its complex property, an indicator that determines the amount of harmful
effects for humans [3]. The environmental friendliness of the product is considered one
of its complex properties and determines the amount of harmful impact on the
environment. The consumer price of the finished product is the sum of its consumption
price and others and the costs of its consumption or use. The description of the product,
which represents its differentiation from competing products both in terms of the

degree of compliance with a specific need and in terms of the costs of satisfying this
need, is called its competitiveness. Quality, like other concepts, has its own system. A
quality system is a set of organizational structures, responsibilities, work procedures,
processes, resources, and the implementation of overall quality management. Selection
of the nomenclature of the quality indicators of the specified product, determining the
values of these indicators and comparing them with the basic values is called the
evaluation of the level of product quality.To evaluate the level of product quality,
products are divided into categories of products that are consumed in use and products
that consume their own resources. Consumable products are used in the process of
using products of the series according to their function [4]. Usually, recycling is an
irreversible process, or it can be the burning of fuel, the assimilation of food products,
and sometimes it can also be a reversible process. When using products of a category
that consumes its own resource according to its function, its resource is consumed. In
this case, the product is used due to its technical and spiritual obsolescence.The
application of the specified description of the product is a number of actions when
choosing the names of a single indicator of a certain group of products, determining
the field of use of the product, selecting one or more samples as the basis, creating
systems of state standards for the names of the quality indicators of the product. creates
relief.It refers to the quality systems of activities that include quality from all sides,
provide all its aspects and cover all life stages of the product. Quality work begins in
the marketing area and ends with the stage of using the waste generated from the use
of the product.The sum of these stages is called a quality ring, and its definition is given
above. Special requirements are placed on the methodological basis of product quality
assessment in quality systems, especially in mandatory and voluntary product
certification, in which a comprehensive analysis and objective assessment of all
properties of the product in consumption, the possibility of demonstrating safety and
environmental friendliness, based on the given assessment, the consumer creation of a
basis for social protection from the risk of the use and environmental protection of the
product and the risk of incorrect assessment of the product and its quality is almost
completely ensured by
The main purpose of evaluating the level of product quality is to justify the
parameters of new types of products, to prepare technical assignments for the
development of products, standards, and technical conditions, and to draw up technical
level cards for new products, to make decisions based on the test results of
manufactured products, to repair products, etc. making a decision is to create a basis
for the product to be sufficiently valued in the market and sold at a reasonable price
[5]. Different methods are used in the evaluation of product quality level: differential,
complex, mixed and statistical methods. The differential method refers to the method
of product quality assessment based on the use of a single indicator of the product. The

differential method is based on the comparison of the indicator of the quality of the
evaluated product with the indicator that is the basis. For example, the service life of
the equipment produced by one enterprise is 8 years, and at the second enterprise this
number is 12 years, the basic value is lower than the basic value, and at the second it
is higher. This indicator was achieved as a result of improving its service life.The
method of product quality assessment based on the use of aggregate indicators of
product quality is called an aggregate method. For example, when assessing the quality
of buses, the generalized quality indicator is their annual productivity. The mixed
method is the evaluation of the quality of the product using both single indicators and
complex indicators at the same time. Mathematical statistical methods are used to
evaluate the quality of the product using the statistical method. Organoleptic method -
product quality is determined by smell, sight, hearing, taste. The chemical composition,
physical, microbiological and technological properties of the product are determined
by the experimental method. The result is expressed in numbers, but the time is long
[6]. The expert method consists of no less than 7 highly qualified specialists-experts-
commodity experts, designers, constructors, and the quality is evaluated according to
their opinion. The expert commission consists of two groups: an expert and a working
group. The expert group evaluates the goods, and the working group performs technical
and organizational work, organization of survey work, distribution and collection of
questionnaires, processing and analysis of expert evaluations.Classification of types of
product testing. Product testing and types of tests are divided into classes according to
international standards. Depending on the purpose of the tests, they can be carried out
for research, for control, for comparison, for determining the value. Research tests are
carried out in the process of experimental processing of a sample item in accordance
with the design document. The purpose of this test is to study certain characteristics of
the property of the object. A real sample can also be used as a test object. In these tests,
information is obtained about the properties of the material or product. This
information is necessary for more effective use of the identified feature.
Control
tests are carried out in order to control product quality, that is, to control the conformity
of the quality indicator achieved in practice with the specified value. These tests are
carried out during the production process. As a result of these tests, the causes of
inconsistency are determined and eliminated, and a recommendation for further quality
improvement is developed. Such tests are carried out only on real samples. Control
tests do not provide sufficient information about product stability. In order to determine
its durability, additional special tests such as long-term durability, non-destructive
operation, storage and other tests should be conducted. The results of control tests are
not only used to determine the unusability of the product, but the statistically processed
result of the control test allows to determine the quality of technological processes and
find ways to further improve it. Each parameter of the control test characterizes the

state of a certain part of the technological process. Comparison tests - testing similar
or identical objects in terms of characteristics in the same conditions in order to test
their properties. Determination test - the previously unknown values of the object
characteristics with specified accuracy and reliability, and if necessary, a random size
distribution is considered a test of determination with legal value [7]. Finished product
testing is a qualification test-testing of the first industrial production batch of the
product in order to assess the readiness of the enterprise to produce a specific product
in a specified volume. Pre-delivery test is a test conducted by the technical service of
the manufacturing enterprise before the product is presented to the customer, consumer
or other receiving office [8].
In conclusion, tests are an integral part of the production process for enterprises
aiming to deliver quality products. By prioritizing testing at every stage of production,
businesses can uphold high standards, meet customer expectations, and achieve long-
term success in the competitive market.
