How Humidity Chambers Improve Global Product Quality

The quality of products is one of the most influential factors that define the success of a brand to compete in the current global economy. Due to this reason, companies in various industries like electronics, pharmaceuticals, automobiles, packaging and consumer goods must make sure that their products are reliable under diverse environmental circumstances.

Manufacturers utilize specialized testing equipment called humidity chambers to assess how their products will perform in these environmental conditions.

Humidity chambers provide manufacturers with the ability to simulate specific temperature and humidity conditions, thereby enabling manufacturers to perform durability and reliability tests using the material or finished product.

What is a Humidity Chamber?

A humidity chamber, also referred to as a humidity testing chamber, is an instrument that simulates a specific relative humidity and temperature to test the ability of products to maintain their functionality and durability.

The main application of a humidity chamber is to replicate environmental parameters that may exist like high relative humidity or low relative humidity or different levels of moisture stored, shipped, or used to determine the impact of moisture on the materials (product) stability, strength, and functions.

These environmental chambers are commonly used in product testing laboratories and in quality control laboratories to assist engineers and quality experts. They help industries to determine if products can withstand the effects of environmental stress before they are tested for failure due to those stresses. The importance of testing products prior to shipping internationally has increased significantly, as products destined for international markets often pass through different environmental climate zones before reaching their final destination.

Modern humidity chambers utilize very sophisticated control systems to maintain both temperature and relative humidity levels very precisely. With outdoor environmental conditions being simulated in a controlled and repeatable manner, manufacturers are able to conduct tests with accurate test data.

Why Do Manufacturing Industries Need Humidity Chambers?

Because environmental elements greatly influence product performance and quality, humidity chambers are used by manufacturing industries. There are several things that can happen to a product because it has been exposed to moisture, such as the material losing strength, the packaging becoming compromised, and, in some instances, the safety of the product being affected.

Industries rely heavily on humidity testing to ensure that their products are reliable. For example, electronic components may fail after being subjected to high humidity levels, and if pharmaceutical products were to be stored in a manner that was considered satisfactory, they would lose their effectiveness. If manufacturers conduct humidity testing on products, they will know if the product will retain strength under different humidity conditions.

Humidity chambers, or environmental temperature chambers, are also important for quality assurance and for meeting accepted international testing standards. Many manufacturing businesses are required to abide by regulatory requirements that mandate businesses conduct environmental testing prior to releasing their product. Conducting humidity testing will allow a manufacturer to meet regulatory compliance while at the same time supporting the manufacturer's global quality standards.

By conducting humidity testing, the manufacturer has the ability to improve product design. During the environmental testing, an engineer identifies weaknesses, and the engineer may be able to improve the product through material, surface treatment, or package design, thereby reducing the potential for failure once the product is distributed and therefore improving customer satisfaction.

How Humidity Chambers Improve Global Product Quality?

Humidity testing has had a huge impact on the ability of manufacturers in international markets to maintain and improve product quality. Humidity chambers allow for manufacturers to simulate environmental stressors and how they affect the performance of a product in its final end-use environment.

• One main benefit of humidity testing is being able to identify product defects early in the product development cycle. By exposing products to controlled humidity during development, manufacturers are able to determine what vulnerabilities exist in the product. Examples of these types of vulnerabilities include corrosion, swelling, adhesive failure, and structural failures. When issues are detected early, manufacturers can modify the design of the product to overcome these issues prior to commencing mass production.

• Another benefit of humidity testing is that it provides manufacturers with consistency in the quality of the products produced. Manufacturing processes can produce different batches of the same product and have variations between the two batches even when both products were produced under the same conditions. Humidity chambers allow manufacturers to conduct tests on materials and components of products under controlled, standardized environmental conditions. This allows manufacturers to confirm that each batch of product is being produced using the same expectations for performance, an important advantage for products that must be distributed across multiple countries.

• Testing packaging materials in humidity chambers before shipment and storage helps confirm that the packaging materials will perform in the humid environment they are being shipped and stored in and that they will maintain their protective properties and strength.
• Another tool that can be used to facilitate innovation during product development is humidity testing. It allows engineers to test how those products work in a simulated environmental condition under a controlled environment, also known as experimenting with new materials, coatings, and manufacturing processes. This enables industries to produce products that are of international standards in terms of durability and performance.

Standard Operating Procedures (SOPs) for Using Humidity Chambers

Accurate and reliable testing results require the proper operation of humidity chambers; Standard Operating Procedures (SOPs) also provide consistency in how tests are performed and how safe they are to perform.

• The first step in using a humidity chamber is to prepare your sample. Any products or materials being tested should be cleaned, labelled and placed in the correct location in the chamber as laid out in your testing plan; if your samples are properly positioned within the chamber, this will help promote even exposure to the test conditions.
• After preparing the sample, you can set the desired environmental conditions for the test. The operator needs to set the temperature and humidity levels required for the test according to testing standards, as they vary from one industry to another and/or product type.
• Once the humidity chamber is operating, it is essential that the operator closely monitor the performance of the chamber to make sure it is maintaining the environmental conditions required during the test; as most modern humidity chambers use some type of digital controllers, the performance of the chamber can be continuously tracked by taking temperature and humidity readings of the environment and comparing them against the expected values; however, operators need to ensure that these readings remain constant during the duration of the test.
• The samples are removed from the chamber and inspected for any signs of damage or degradation including signs of corrosion, deformation, or other changes. By observing these conditions, engineers will determine whether the product conforms to the accepted quality control criteria for that particular product.

Conclusion

Many industries heavily rely on the environment in which they manufacture and use their products for their durability and performance. Of particular concern with respect to material strength and the integrity of packaging materials is humidity. Additionally, manufacturers who sell products around the world must assess how their products respond to varying levels of humidity since manufacturers can be affected by the humidity present in the worldwide marketplace.

The use of humidity chambers allows manufacturers to create simulated climatic conditions in a controlled environment so that they can test how products will perform based on these conditions. By conducting tests on their products while using humidity chambers, manufacturers can identify any weaknesses in their products, as well as enhance product design, ensure compliance with international regulatory standards and maintain product quality.
