5 Main Types of Inspections in Quality Control Pre-Production Inspection (PPI) The very first inspection that takes place following a purchase order is known as a pre-production inspection. First Article Inspection (FAI) During Production Inspection (DPI) Pre-Shipment Inspection (PSI) Container Loading Inspection (CLI).
What are most basic and common visual inspection method?
Visual Inspection, or Visual Testing (VT), is the oldest and most basic method of inspection. It is the process of looking over a piece of equipment using the naked eye to look for flaws. It requires no equipment except the naked eye of a trained inspector.
Which is used for visual inspection?
A visual inspection is an inspection of an asset made using only the naked eye. This kind of inspection does not necessarily require any special equipment, but it does require special training so that the inspector knows what to look for as they visually review the asset.
Is standard for visual inspection?
Policy: Visual Inspection Standards (VIS) provide relaxations from the surface condition (normally flawless) implied by engineering drawings. Only those relaxations (called imperfections) allowed by this VIS, or the engineering drawing are permitted on parts to which this VIS is assigned. 3.

What are the 4 types of quality inspection? Pre-Production Inspection (PPI) During Production Inspection (DPI) Pre-shipment inspection (PSI) Container loading/loading supervision (LS) Piece-by-piece Inspections.
What are the 3 types of quality inspection?
There are three primary types of quality inspections: pre-production, in-line, and final. There are a variety of details that must be inspected and approved during each phase in order to detect and correct quality problems.
What is an inspection method?
In engineering, inspection involves the measurements, tests, and. gages applied to certain characteristics in regard to an object or activity. The results are usually compared to specified requirements and standards. for determining whether the item or activity is in line with these targets.
Which one of the following is a type of Visual inspection?
Explanation: Visual inspection can be used for detection of many kinds of defects like cracks, tears, blowholes, rattails, metal penetration, swells, shifts and many more.
What type of test is Visual inspection test Mcq?
Clarification: Visual inspection is a type of non -destructive testing technique that provides a means of detecting and examining the variety of surface flaws, such as surface finish, discontinuities and surface cracks on the castings.
What are the optical inspection methods?
Following are the four main categories of optical inspection: Optical Comparators. As the name suggests, the optical comparators use normal optics to magnify and project the image of the object on a glass screen. Video Systems. Microscopes. Laser Systems.
What is visual and optical testing?
Visual and Optical Testing is one of the essential inspection method of non-destructive testing. Visual testing requires adequate illumination of the test surface and proper eye-sight of the person performing this inspection.
Where is ultrasonic testing used?
In industrial applications, ultrasonic testing is widely used on metals, plastics, composites, and ceramics. The only common engineering materials that are not suitable for ultrasonic testing with conventional equipment are wood and paper products.
Which standard is used for the basic requirements for visual inspection?
The general principles standard is the overall standard for visual testing generally and is not specific to any product.
Which year did mandatory visual testing start?
This method involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities such as corrosion, misalignment of parts, physical damage and cracks.
What are the minimum lighting conditions for visual inspection?
The requirements of visual examination are: Illumination should be at least 350 Lux (minimum) but it is recommended to carry out visual inspection at an illumination of more than 500 Lux.
What is inspection in metrology?
Definition. In the field of Precision Engineering and Metrology, inspection can be defined as the set of hardware, software, procedures, and activities that can provide measurements of geometric characteristics of physical manufactured products.
What is a quality inspector?
Quality control inspectors monitor quality standards for nearly all manufactured products, including foods, textiles, clothing, glassware, motor vehicles, electronic components, computers, and structural steel. Inspectors in these firms monitor the equipment, review output, and conduct random product checks.
How many types of quality inspection are there?
The 4 types of quality inspection services. Four types of quality inspection services are usually distinguished. Each one corresponds to a particular step in the production process.

What type of process is quality inspection?
Quality control (QC) is a process through which a business seeks to ensure that product quality is maintained or improved. Quality control involves testing units and determining if they are within the specifications for the final product.
What are the different types of inspection method used in metrology?
The most common inspection methods for parts today include contact and noncontact instruments such as machine vision systems, microscopes and coordinate measuring machines. Noncontact inspection systems include laser micrometers, vision measuring machines, profile projectors and microscopes.
What is inspection method SAP?
Purpose. You use inspection methods to describe how to carry out an inspection for an inspection characteristic. You can create master inspection methods at plant level to simplify and standardize the inspection planning activities and to standardize the nomenclature.
What is the main purpose of inspection?
To inspect is to carefully examine. The main objective of inspection is to meet customer requirements, wants, and needs. The objective is to prevent defective product flowing down the successive operations and prevent loss to the company. Many characteristics cannot be inspected at the final stage of production.
