APPENDIX 1 (for reference). EXPLANATIONS FOR SOME TERMS

ANNEX 1
Information

To the term "Maintenance"

Maintenance contains operations regulated in the design documentation to maintain the functionality or serviceability of the product during its service life.

In accordance with GOST 3.1109, a maintenance operation is understood as a completed part of the maintenance of a component of a product, performed at one workplace by a performer of a certain specialty.

Transportation refers to the operation of moving cargo along a specific route from the place of loading to the place of unloading or reloading. Transportation of self-propelled products does not include moving them under their own power.

Waiting means the product being in a state of readiness for its intended use.

Maintenance may include washing the product, monitoring its technical condition, cleaning, lubrication, fastening bolted connections, replacing some components of the product (for example, filter elements), adjustment, etc.

To the term "repair"

In accordance with GOST 3.1109, a repair operation is understood as a completed part of a repair performed at one workplace by performers of a certain specialty.

Repair may include disassembly, troubleshooting, monitoring the technical condition of the product, restoration of parts, assembly, etc. The content of some repair operations may coincide with the content of some maintenance operations.

Repair of products can be carried out by replacing or restoring individual parts and assembly units.

Repairs of any kind, as a rule, must be accompanied by the issuance of certain guarantees for the subsequent service life or operating time of the product.

To the term "System of technical maintenance and repair of equipment"

In a particular case, the equipment maintenance and repair system may include materials, workpieces, spare parts, etc., i.e. it is characterized by logistics, which can be defined as the ability of a service organization to provide the necessary resources to carry out maintenance and repair of an object under a given strategy and under given conditions. The specified conditions apply both to the object itself and to the conditions of its operation, maintenance and repair.

To the terms "Maintenance cycle" and "Repair cycle"

In a particular case, the start of the maintenance cycle (repair cycle) may be the beginning of use of the product.

To the term "Periodic maintenance"

Periodic maintenance may differ in the content of the operations. In this case, maintenance is numbered in ascending order, for example, shift maintenance, TO-1, TO-2, TO-3, etc.

To the term "Seasonal maintenance"

Seasonal maintenance includes operations of replacing seasonal grades of operating materials with flushing of the corresponding systems, installation and removal of insulation and engine preheating devices, etc.

Seasonal maintenance is carried out only for products used during significant changes in environmental conditions during the year.

To the term "Scheduled maintenance"

Maintenance schedules can be strict and tolerant. The type of regulation must be established in the operational documentation.

To the term "Method of maintenance by specialized personnel"

Maintenance personnel may be specialized by type of facility, brand of facility, type of operation, and type of maintenance.

To the terms "Major repairs", "Medium repairs", "Current repairs"

Major, medium and current repairs can be planned or unplanned.

The base part is understood as the main part of the product, intended for its assembly and installation of other components.

To the term "Unscheduled repairs"

Unscheduled repairs are carried out to eliminate the consequences of failures or incidents.

To the term "Aggregation repair"

Replacement of units can be carried out after a product failure or according to a plan. The list of units to be replaced, the procedure for replacement and instructions for organizing unit repairs are established in industry normative and technical documents.

The opposite of the aggregate method is the detailed method, in which individual parts that have failed are replaced or restored.

To the indicators of the maintenance and repair system

Indicators of the maintenance and repair system allow you to estimate the costs of time, labor and money for maintenance and repairs and contain costs due to the design and technical condition of the product (operational costs), and costs due to the organization, technology for performing maintenance and repairs, material and technical provision, personnel qualifications, environmental conditions, etc.

The indicators of the maintenance and repair system in paragraphs 57-65 evaluate the total costs of time, labor and money for maintenance and repairs and contain costs due to the design and technical condition of the product (operational costs), and costs due to the organization, technology of maintenance and repairs, logistics, personnel qualifications, environmental conditions, etc.

The calculation of indicators for the system of technical maintenance and repair of equipment is similar to the calculation of the corresponding maintainability indicators according to GOST 21623. In this case, instead of operating costs, the total costs of time, labor and money are taken into account.
