What is the Module C2 Standard?

Module C2 is one of the conformity assessment modules defined under the European Union's New Approach Directives. This module entails a system where the manufacturer implements internal production control, while product inspections are conducted at specific intervals by an authorized body.

In this context, the following are assessed:

• Internal production control processes,

• Random product sample checks,

• Technical documentation reviews,

• Production process evaluations,

• Checks for conformity to the product type,

• Compliance with relevant regulatory requirements

are evaluated.

Module C2 is applied particularly to safety-critical product groups, such as pressure equipment.

How is a Module C2 Certificate of Conformity obtained?

The Module C2 conformity process is conducted as a combination of production process control and random product inspections.

The process generally consists of the following stages:

• Examination of the technical file,

• Evaluation of production processes,

• Verification of the internal production control system,

• Selection of random product samples,

• Testing of products,

• Performance of dimensional and mechanical checks,

• Evaluation of regulatory compliance

The conformity certification process is completed once the conformity of the products to the type is verified based on the evaluations performed.

Why is Module C2 Applied?

Module C2 is implemented to ensure that production processes remain under continuous control and that products are manufactured to specific quality levels.

The reasons for implementing this module are as follows:

• Ensuring product safety,

• Maintaining control over the production process,

• Verifying conformity to the type,

• Ensuring compliance with regulatory requirements,

• Supporting quality consistency through random checks,

• Supporting CE marking processes.

What Are the Application Areas of Module C2?

Module C2 is widely used, particularly in the manufacture of pressure equipment.

Its primary areas of application include:

• Pressure vessels,

• Industrial boilers,

• Pressure piping systems,

• Gas and liquid transport equipment,

• Power plant equipment,

• Chemical and petrochemical plants,

• Industrial process equipment,

• High-pressure systems.

Equipment and Techniques Used Within the Scope of Module C2

Various testing and inspection methods are employed during the conformity assessment process, depending on the nature of the product.

The equipment and techniques used include:

• Pressure testing systems,

• Hydrostatic testing devices,

• Mechanical testing equipment,

• Non-destructive testing (NDT) methods,

• Spectrometers,

• Dimensional measurement equipment,

• Visual inspection techniques,

• Review of production records.

These methods are used to verify the conformity of the products to the relevant standards.

Module C2 Advantages

• Ensures production processes remain under control.

• Enhances product reliability.

• Supports quality consistency through random inspections.

• Strengthens regulatory compliance.

• Contributes to verifying production conformity to the type.

• Supports CE marking processes.

Module C2 Disadvantages

• The requirement for regular inspections may affect production planning.

• Testing and inspection processes may require additional time.

• It necessitates keeping production records constantly up to date.

• Random inspections may require additional preparation in operational processes.

Nevertheless, the process establishes a significant system for product safety and quality control.
