Inspection Services

The inspection services involve checking something, i.e., assessing and examining something. For example, people inspect buildings, machines, and organizations to ensure they are up to standards.

Inspection Services
  • Interpretation of specifications/drawings.
  • Measurement of dimensions or other related parameters.
  • Selection of proper instruments and gauges.
  • Selection of units of measurements.
  • Comparison between specified and measured values.
  • Based on the act of comparison, proper decisions are to be taken.

The organization which uses quality inspection treats the inspector as a customer. Therefore, the optimum quality inspection form is the man aiming for the best customer satisfaction. Quality Inspection has three main purposes.

  • To judge whether the product conforms to specification.
  • To decide whether Non-Conforming Product is for use.
  • To determine what to communicate to outside & Insides.

In Business, an Inspection is the critical appraisal of items, systems, and materials. They involve examining, testing, and gauging. Inspectors take measurements and make a comparison. In manufacturing, Inspections are a vital component of quality control.

Objectives of Inspection Services

  • It separates defective components from non-defective ones.
  • Defective parts are rejected before reaching the customer’s end.
  • To find a defect in raw material.
  • Rejected parts identified in WIP and prevented further activity.
  • It will decrease all-over rejection PPM.
  • To establish and increase their reputation by protecting customers from receiving poor quality standards.
  • Detect the source of weakness and failure in the finished products and thus check the designer’s work.

Why do we need an Inspection in Pakistan?

  • It separates defective components from non-defective components.
  • Rejected part capture during WIP & the cost of further action will be saved.
  • The bad part not reaching to customer end.
  • To find out defects in Risk Management errors during manufacturing.
  • It prevents further work from being done on the defective product.
  • It helps the components to sustain their reputation by maintaining quality standards.
  • To make decisions on the faulty parts.
  • It helps to coordinate the functions of quality control, production, purchasing, and other organization departments.
  • Provide the means of finding out shortcomings in manufacture.

What are the types of Inspection?

Attribute Inspection

Evaluation can be performed by using the innate senses of Human beings (that is, Smell, Taste, Sight, Hearing, and Touch).

Variable Inspection

The inspection & Testing evaluation is determined using any measurement device, e.g., H.G., V.C., BP, Laser, or Chemical Device.

Based Upon Method of Inspection

  • Incoming Inspection.
  • In-Process Inspection.
  • First Piece & List Piece Inspection.
  • Final & PDI Inspection.
  • Layout Inspection (Ballooning Drawing).
  • Suspected Lot Inspection.
  • Sampling Inspection.
  • Pilot Piece Inspection.
  • Visual Inspection.
  • Final Assembly Inspection.

There are some other types of Inspection as per the different industry types of APOP, TPI (Third Party Inspection).

What are the methods of Inspection?

1. 100% Inspection

This type will involve careful Inspection of quality at each strategic point or stage of manufacture where the test applied is non-destructive, and every piece is separately inspected. It requires more inspectors, and hence it is a costly method. There is no sampling error. This is subjected to inspection error arising out of fatigue, negligence, the difficulty of supervision, etc.  Hence complete accuracy of influences is seldom attained.

It is suitable only when a small number of pieces are there or a very high degree of quality is required.
Examples of 100% Inspection: Jet engines, Aircraft, Medical, and Scientific equipment.

100% inspection is not preferred in the industry for mass production due to the following reasons

The cost required for Inspection is more as compared to sampling inspection.
The time needed for Inspection is more.
The operator suffers from inspection fatigue.
More staff is required for Inspection.
Due to more handling, the chances of damage increase.
100% Inspection is not possible where destructive testing is required.

2. Sampling

In this method, randomly selected samples are inspected. Samples taken from different batches of products are representative. If the sample proves defective. The real concern is to be rejected or recovered.

Sampling inspection is cheaper and quicker. It requires fewer inspectors. Its subjected to sampling errors, but the magnitude of sampling error can be estimated.
In the case of destructive tests, random or sampling Inspection is desirable.
This type of Inspection governs wide currency due to the introduction of the automatic machine of equipment which is less susceptible to chance variable and hence require less Inspection, suitable for Inspection of products that have less precision importance and are less costly.

What is the purpose of Inspection?

  • To distinguish good lots from bad lots.
  • To distinguish good pieces from bad pieces.
  • To determine if the process is changing.
  • To determine if the process is approaching the specification limits.
  • To rate the quality of the product.
  • To place the accuracy of inspectors.
  • To measure the precision of the measuring instrument.
  • To secure products – design information.
  • To measure process capability.

What are the stages of Inspection?

There are three stages of Inspection.

  1. Inspection of incoming materials (RQC).
  2. Inspection of the production process (In-Process Inspection).
  3. Inspection of finished goods (PDI).
