Sometimes a defect is detected in your company or in the field and you have the need to certify the quality of the material by performing an inspection or drawing of the entire lot.
Inspection systems are used to examine and measure the characteristics of a product, as well as the components and materials from which it is made, or a specific service or process. The inspection process is that process that consists in verifying all the units of a lot.
An inspection to allow only parts of the specified quality to be accepted, but when the inspection is carried out manually, two types of problems are presented, one would be the expense involved and the other, the precision of the inspection, considers an error.
Quality inspection consists in examining and measuring the quality characteristics of a product, as well as its components and materials from which it is made, or a specific service or process, all using measuring instruments, comparison patterns or equipment. tests and tests, to see if it meets or not the specified requirements.
The types of errors that can be made during a quality inspection of a process are:
- Type I: it is the error that is committed when a product is rejected being correct, complying with all the parameters that we have defined as of good quality.
- Type II: it is the error that is committed when a sample is given as a good that is not really within the parameters that we have defined as valid, and this sample is admitted when it still has undesired defects.
Inspections can be carried out by different methods and classified in several ways. When quality assurance is carried out, it is necessary to occasionally review the inspection plans when investigating what kind of inspections should be carried out at each stage of the manufacturing process.
