Process Validation Types Revalidation

Fourth type of process validation is Revalidation. It is performed to check the performance of the various process parameters, some of the points regarding revalidation are as follows. So let us have a look on revalidation:

Any part of process or entire process parameters are validated in order to check the performance of the process parameters.

To maintain the validated status of equipment, facilities, or manufacturing process , revalidation if often carried out.

Revalidation is generally performed when product from one plant it transferred to another plant.

If there is any change in the process parameters or the product quality then revalidation is performed.

There is periodic checking of all the process parameters.

If the batches fails to meet the specifications and this (OOS) repeated in sequence then revalidation is done.

The revalidation of manufacturing process depends on the changes of any process parameters, facilities or any change in the equipment parameters .

  • Process Validation parameters

    Parameters of Process Validation for successful validation of any process are discussed here. Some of the key parameters in process validation are as follows, so let us check it out one by one.

    The knowledge and the information about the product and the process is very necessary.

    Understanding of the source of variation is required for successful process validation.

    One must be aware about the impact of the variation on the process and ultimately on the products which is being manufactured.

  • Process Validation

    Process validation: It can be defined as the documented evidence which provides a high degree of assurance that the process which is going to be performed will consistently produce a product , meeting its pre determined specifications and all the quality attributes.

    Process Validation is classified into four types which are as follows:

    Prospective Validation

    Retrospective Validation

    Concurrent Validation

    Revalidation

    Process Validation is divided into three stages which are  as follows:

    Process Design - Stage I

  • Process Validation Types

    Types of Process Validation: There are mainly four types of process validation. Following are some of the types of process validation so let us see all types one by one:

    Concurrent validation is performed based on the data which is generated at the time of production.

    Validation carried out on the bases of the actual report generated during production.

    Critical process parameters and the end products are monitored during concurrent validation.

    The process parameter are checked for each and every ongoing batch.

  • Process Validation Stages process qualification protocol

    During Process Validation the protocol of process qualification is also prepared, following are some of the points which are included into protocol of process qualification, so let us check it out some points:

    The manufacturing condition including processing limits, the operating parameters as well as the components used such as raw materials are included in protocol.

    The sampling plan with complete details of the number of sampling points, frequency of sampling of each unit are to be mentioned in protocol.

  • Process Validation Stages process qualification two

    In the Process Validation during second stage that is process qualification some more points are taken into account which are  discussed below. So let us see some points one by one:

    During process performance qualification the actual facilities, utilities and equipment are checked whether they are qualified or not.

    The personnel operating various equipment are trained or not is checked.

    The  procedure which are performed are as per standard procedure is verified and checked.

  • Process Validation stages continued process verification

    Third stages in Process Validation is Continued Process Verification, Some points in process validation during continued process verification are as follows, So let us see one by one all the points:

    The main goal of continued process verification in process validation is to ensure that the process remains in a state of control during manufacturing of commercial products.

    The data is collected and evaluated in order to determine process variability.

  • How Recycling Saves Energy?

    When we manufacture new products from virgin materials, more energy is consumed. Other natural resources such as fossil fuels (Oil , Petroleum, Natural gas, Coal) are also used during manufacturing of products. But when we make products out of recycled materials we can reduce the use of energy sources. The steps in the process of manufacturing of recycled product is reduced which helps to save energy.

  • What are environmental benefits of Recycling ?

    There are several environmental benefits of recycling. Let us check it out some of the points of recycling to know more about recycling.

    The process of recycling helps to reduces noxious waste in landfills. Recycling also helps to promote environments sustainability. By this entire process it is possible to diminish the demands of raw materials. Ecological degradation can also be prevented by the process of recycling, 

  • Line Clearance

    Line clearance is the permission taken from the authorized QA person before starting actual production (Manufacturing, Filling and Packaging). 

    The line clearance includes:

    Manufacturing Area

    Filling Area

    Dispensing or packaging Area

    Purpose and Importance

    In line clearance the procedures have been established to prevent mix - up of containers, products, labels and mistakes in documents. MIx up and mistakes occurs when GMP are not followed.

    Particular take should be taken:

    When starting a new operation

    At change of shift

  • Processes involved in Recycling materials

    There are mainly four types of process involved in recycling materials. So let us check it out each process take place during recycling of any materials or products

    The first step is to collect recyclable materials such as paper, glass, aluminium, cans, plastic from communities. The recyclable materials are placed into separate bins and the bins also have the recyclable symbol on it. 

  • What is the Full Form of IQ?

    IQ - Intelligence Quotient

    IQ is the parameter or the score which is obtained from several tests and used to measure the intelligence of a person.

    The parameters of IQ are different for different people under various conditons. For example the parameters for the student and the person appearing for the IAS exam are different.

    For students, IQ is used to check whether student is fit for further education or not.

  • Benefits of Recycling

    Recycling is a process of waste management in which waste materials of plastic, paper, metal, aluminium, glass etc., are collected and are used to make new products. Recycling helps to protect the environment and saves energy and resources.
