Factory Acceptance Test

Factory acceptance test (FAT) is an inspection and testing activity to check and make sure that the equipment has good quality (physic and work). This test can be done in the place that it is assembled or built.This test also to check and fit with specification of equipment. This test sometimes is done before equipment will be shipped.

Factory acceptance test have to be attended by user, vendor and customer. That is fair. Every one should know about status of equipment. Customer as buyer, user as people that use it and vendor as assembler or creator. All of attendant have to know and agree.

But this test not always have not to be 100 % clear, because suit with acceptance between vendor, customer and user can be tested again after arrive in the place, and vendor can repair and make sure again in other time.

This procedure shall be attended by vendor and customer, and have to accepted by both.

Below is a sample of procedure and guideline to do FAT, this is taken from www.sp.se.

Factory Acceptance Testing Guideline Process

In installation step, by contractor or anyone, this document have to be referenced and should be attached in dossier as a note of installation step.

P and ID

A Piping and instrumentation diagram/drawing (P&ID) is defined by the Institute of Instrumentation and Control as follows:

1. A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on Instrumentation, Systems, and Automation Society (ISA) Standard S5. 1.
2. The primary schematic drawing used for laying out a process control installation.

P&IDs play a significant role in the maintenance and modification of the process that it describes. It is critical to demonstrate the physical sequence of equipment and systems, as well as how these systems connect. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational investigations, such as the popular Hazards and Operability (HAZOP) study.

For processing facilities, it is a pictorial representation of

• Key piping and instrument details
• Control and shutdown schemes
• Safety and regulatory requirements and
• Basic start up and operational information

List of P&ID items

• Instrumentation and designations
• Mechanical equipment with names and numbers
• All valves and their identifications
• Process piping, sizes and identification
• Miscellanea – vents, drains, special fittings, sampling lines, reducers, increasers and swagers
• Permanent start-up and flush lines
• Flow directions
• Interconnections references
• Control inputs and outputs, interlocks
• Interfaces for class changes
• Computer control system input
• Identification of components and subsystems delivered by others
