Equipment validation versus calibration

Please, how do we differentiate between equipment validation and equipment calibration, am getting confused with the two.
Also how is it done

Calibration is part of Validation.
Validation is qualifying your equipment for the intended use. It’s a dry run of the process which includes calibration.
Hope that’s clear.

Calibration is a demonstration that, a particular
Instrument or device produces results with in specified limits by comparisons with those produced by a reference or traceable standard over an appropriate range of measurements.

Validation is a documented program that provides high degree of assurance that a specific process, equipment, method or system consistently produces a result meeting pre-determined acceptance criteria.

Calibration ensures that instrument or measuring devices producing accurate results.

Validation provides documented evidence that a process, equipment, method or system produces consistent results (in other words, it ensures that uniforms batches are produced).

In calibration performance of an instrument or device is comparing against a reference standard.
No such reference standards are using in validation program.

Equipment qualification is a systematic procedure, which ensures that suitable equipment
is purchased and that it remains fit for its chosen purpose throughout its operating life. whereas calibration using traceable standards or reference materials is an important factor in
obtaining accurate results, which are consistent with measurements made in other
laboratories. Qualification is the responsibility of both the vendor and user; and as
control of the instrument moves from vendor to user, so this balance shifts more towards
the user. However, the manufacturer is not totally devolved of all responsibility, and is
still required to prove the use of “suitable reference materials” for establishing the
validity of the initial calibration of the system.
