An external quality control of production processes or raw materials are necessary to be able to offer guarantees of use and durability. For this, their properties and characteristics are evaluated. These types of tests are carried out in the quality laboratories of the companies and follow the standards defined, both by the corresponding national regulations and the quality standards defined by the company. In today’s post we tell you more about what external quality control is and what its purpose is in a company; what are the types of existing external control and the differences with internal quality controls.
An external quality control laboratory is in charge of monitoring and ensuring the quality of one or several properties of a product or material and which, furthermore, is independent of the company that owns said product. These are the objectives to be achieved in terms of performance, efficiency and satisfaction of the end customer. As a result, a report or certificate is prepared, depending on the type of laboratory, and the property being studied. For example, ATRIA would be a model of an external quality laboratory.
The purpose of an external quality department is to provide greater independence to the results. In this way, the company can offer a greater guarantee to its clients that the results are always objective. These external quality controls can be carried out in a preliminary, concurrent or feedback way, depending on the point at which the analysis is carried out. In addition, these analyzes that are carried out periodically, can be done in each batch that is received, each day, each month, each year, etc.
In this section we will discuss some types of external quality controls depending on the property that we want to know. Some of them are the following although there are more:
In addition, with external quality controls, numerous properties of materials and finished products can be evaluated. From ATRIA, the properties have been grouped into the three most outstanding categories
As mentioned at the beginning of the post, external quality control is carried out in an independent laboratory that is not linked to the company that manufactures the product or material. Likewise, independence in the conduct of the test is guaranteed. However, with internal quality control the opposite is true.
Another point to discuss are the advantages of carrying out external quality controls compared to doing it internally. Some of these benefits are in the following lines:
Realiable and independent tests
Innovative and nonibred solutions
Speed results
Testing and evaluation with internal results
Blind samples
Rekease workload to the internaal quality department
Confidentiality
Extensive experience of external personnel in test equipment
Chemical analysis upon receipt of raw materials
Impurity analysis
Lubricant analysis
Chemical analysis of generated waste
Homologation tests
Colorimetry control
Volatiles Identification
Packaging control
Monitoring of the manufactured product
Improved production efficiency
In this case, the service began with an engineering project for our client TodoCESPED. In this company, they have established very high quality standards and, to ensure them, they need to verify that their artificial grass withstands the discoloration that certain surfaces can suffer with continuous exposure to the sun over time.
From ATRIA, we created a protocol with the use of an infrared spectrometer, which allows us to analyze that the raw materials for the manufacture of grass have the necessary quality for the requirements of TodoCESPED and, therefore, of its clients.
This type of technique has been carried out since then on all the batches of materials that TodoCESPED receives, with the aim of detecting any situation that does not match its parameters of excellence before manufacturing and launching the product on the market.
