Types of Inspections

Inspections can be divided into several types, including Floor Inspection, Centralized Inspection, Combined Inspection, Functional Inspection, First Piece Inspection, Pilot Piece Inspection and Final Inspection. The following is a brief discussion.

Floor Inspection: is an inspection conducted in the production process. In Floor Inspection, the Inspector inspects Material or semi-finished products (Semi Goods) in the production process, whether done by humans or machines. Inspector will carry out inspection from one machine / worker to another machine / worker. This inspection method can detect problems early before the product is produced in large quantities.

Centralized Inspection: is an Inspection that is carried out at a certain location or centered at a specified place. All Testing Equipment and Machines are placed in a place devoted to testing. All product samples that will be tested will be brought to the location for testing.

Combined Inspection: is a combination of Floor Inspection and Centralized Inspection.

Functional Inspection: is a functional inspection of the product. As an example, in checking the function of a motor, Functional Inspection will check the characteristics of the motor speed according to the specified without having to know the characteristics of each component forming the motor. Functional Inspection is generally carried out after a product has become a Finished Product.

First Piece Inspection: is an inspection conducted on the first unit. The first unit in question could be the first unit at the shift of work shifts, the first unit at the LOT product change, the first unit at the change of work tools or the first unit at the change of machine parameters.

Pilot Piece Inspection: 
is an inspection conducted on new products or new models

Final Inspection: is an inspection conducted on Finished Goods. This Final Inspection examines the overall characteristics of the product both Functional and Cosmetics. Final Inspection is done before the finished product is sent to the customer.

Methods of Inspection in Quality Control: There are two methods of doing Inspections (Inspection), namely the 100% Inspection method (100% Inspection) and the Inspection method by sampling (Sampling Inspection).

100% Inspection Method: is an Inspection carried out on all products produced by the production and testing techniques used must not be destructive (not damage the product). The 100% inspection method requires a lot of labor and high costs. This 100% inspection method is usually applied to high-priced products.

Sampling Inspection Method: is an inspection conducted on a certain number of samples from the total number of products produced in a certain time span. Samples taken in general are random samples (random samples) that represent the entire product population (generally based on models, labor, machinery or a certain time span). If the inspection is proven to detect a defective product then all related products will be rejected (rejected) and must be reworked or re-sorted. Inspection or Inspection of Sampling is cheaper and faster but has the risk of sampling error. This sampling error can usually be estimated. In the case of destructive testing that is testing that can damage the product concerned, this sampling inspection is highly recommended. This Inspection Sampling Method is usually carried out on products that are less precise and not expensive.
