What is the Module A2 Standard?

Module A2 is one of the conformity assessment modules defined within the framework of the European Union's New Approach Directives. This module features a hybrid structure that combines internal production control with product checks.

In this context, the following are carried out:

• Internal production control system,

• Random product sample checks,

• Technical documentation reviews,

• Production process control,

• Product traceability system,

• Assessment of conformity with regulations

are carried out.

Module A2 is applied particularly to safety-critical products, such as pressure equipment.

How is the Module A2 conformity process carried out?

The Module A2 conformity process is carried out through a combination of a production control system and periodic external audits.

The process generally consists of the following stages:

• Examination of the technical file,

• Evaluation of the internal production control system,

• Examination of production processes,

• Selection of random product samples,

• Performance of pressure and strength tests,

• Dimensional and visual inspections,

• Verification of conformity with regulations

stages.

The assessment determines the conformity of the products with the relevant directives and standards.

Why is Module A2 applied?

Module A2 enhances the level of safety by ensuring that production processes are verified through both manufacturer control and independent inspection.

Reasons for implementing this module:

• Maintaining control over production processes,

• Ensuring quality assurance through random inspections,

• Increasing the safety of pressure equipment,

• Supporting CE conformity processes,

• Verifying production conformity to the type,

• Ensuring compliance with European Union regulations.

What are the application areas of Module A2?

Module A2 is widely applied, particularly to pressure equipment manufactured in series.

Key areas of application:

• Pressure vessels,

• Industrial boilers,

• Pressure piping systems,

• Gas and liquid transport equipment,

• Power plants,

• Chemical and petrochemical industries,

• Industrial production lines.

Equipment and Techniques Used Under Module A2

Under Module A2, products undergo various tests and inspections during both the production process and the inspection stage.

Equipment and techniques used:

• Hydrostatic pressure testing equipment,

• Mechanical testing machines,

• Non-destructive testing (NDT) systems,

• Dimensional measurement equipment,

• Spectrometer analyzers,

• Visual inspection methods,

• Quality record and documentation reviews.

These methods are used to verify the products' conformity with regulations and standards.

Module A2 Advantages

• Secures production processes with a dual-check mechanism.

• Ensures consistent quality through random inspections.

• Supports CE conformity processes.

• Enhances product reliability.

• Strengthens the traceability system.

• Improves quality control in mass production.

Disadvantages of Module A2

• Periodic inspections can affect production planning.

• Testing and inspection processes may require additional time.

• It can increase the documentation burden.

• It may create a need for additional preparation in operational processes.

Nevertheless, Module A2 is a significant conformity mechanism for pressure equipment regarding safety and quality.
