A hast test chamber is also known as a Highly Accelerated Stress Test Chamber. It is a generalized form of equipment used to examine appliances. This chamber is for use in quality engineering. The HAST Chamber of Commerce checks whether the system and devices work or not. This technique determines the performance of machines and devices under adverse environmental conditions. The main purpose of the hast chamber is to activate the aging process of electronics. This is important for the durability and reliability of the equipment.

Types of HAST Test Chambers

There are 2 types of these chambers which are below:

ESPEC Chamber

ESPEC Chamber

It is one of the most popular types among all types of hasting chambers. This is manufactured by ESPEC Co Ltd. One of the top companies of environmental test chambers. ESPEC hast chambers expose the components and devices to high humidity and temperature. ESPEC chamber is well-known due to its durable design, temperature, and humidity control. Also, it has some other features that support reliability and testing assessment. These hasting chambers of commerce are used in automotive, aerospace, and electronics. Also, they are beneficial for telecommunication industries to access functionality and resistance.

Hirayama HAST Chamber

Here is another Hirayama chamber. Hirayama is a well-known manufacturer of environmental test equipment such as hast chamber. Hirayama hast chamber has a precise temperature and humidity control design. This design is for repeatable and accurate testing of electronics. According to the exhausted mode, it maintains humidity spontaneously. First, it cools down, then it increases the humidity in fast cooling mode and then is the exhaust mode. The chamber consists of 20 terminals. 60 terminals are for the first 2 models, PC-304R8 and PC-304R8D. 80 terminals are for PC-422R8 and PC-422R8D. Model PC-422R9 has 20 terminals. Hirayama is exactly like ESPEC functionality. Also, it is reliable for reliability testing. Many devices like LCD boards, capacitors, batteries, and resistors have high pressure, humidity, and temperature. Hirayama has two modes: saturated and unsaturated control modes.

Functions of Hasting Chamber

There are several functions and benefits of these chambers as follows:

  1. A hast chamber enables fast testing of products. This is due to exposure to high temperatures and humidity. This testing allows product evaluation in a short period. Also, it monitors the environmental conditions. It is also called accelerated testing.
  2. These test chambers give information about environmental conditions. This includes temperature and moisture. They are authentic under the low conditions of the environment. Thus, these simulations provide an idea about the performance of machinery.
  3. In a controlled environment, these chambers result in product failure. These product limitations are helpful to improve design, selection of material, and processing. Thus, this helps to increase product durability and reliability.
  4. Quality control: The manufacturer tests the quality in these chambers. This enables us to address and recognize design flaws. Due to this, there is no compromise on functionality, durability, or security.
  5. Compliance testing: This is to adhere to several industry-specific norms and rules. Products are subject to testing in harsh conditions by industry standards in hast chambers. Through testing, items confirm to meet the necessary performance and reliability standards.
  6. The fundamental requirements are humidifying, heating, and pressuring the vessel interior.

Uses of HAST Chamber of Commerce

The hast chamber is to ensure the integrity and avoid temperature and humidity leaks. These chambers have a sturdy outer stainless steel shell or other lasting materials. The interior of the chamber has a lining of material that resists corrosion.

Uses Of HAST Chamber Of Commerce
  • Temperature Control: These test chambers have a method for temperature control. They produce a wide range of temperatures, -40 to 200 degrees C or more. This temperature control system uses heating and cooling systems for temperature changes.
  • Humidity Control: HAST test chambers contain a humidity system for high humidity values. The relative high humidity values are up to 95-98%. The system uses steam generators, humidity sensors, and water reservoirs to maintain humidity.
  • Pressure Control: It also set up pressure conditions inside the chamber. This is important for evaluating aircraft components, or sealed enclosures.
  • Monitoring And Data Recovery: The systems in these chambers record and track characteristics. These include temperature, pressure, time, and humidity. This is essential for assessing the effectiveness of tested items.
  • Safety Features: These have safety features to protect the operator and the environment. The features include over-temperature, emergency, over-pressure, and alarms.
  • Viewing Window And Lighting: The chambers have windows of glass or other material. They regulate the environment and give appropriate illumination. Also, they include lighting systems.

Applications of HAST Chamber of Commerce


Test and assess electronic components including integrated circuits (ICs), printed circuit boards(PCBs), connections, and other electronic devices. Hasting chambers are widely used in the electronics sector. They aid in evaluating the validity.


Automotive components like sensors, electronic control units(ECUs), switches, and connectors are tested in these chambers in the automotive sector. To ensure the performance and longevity of these components, these chambers irritate the extreme temperature and humidity conditions that might be experienced in various climates or difficult settings.


To ensure its functionality and dependability under a variety of environmental conditions, telecommunications equipment, such as routers, and antennae, is subjected to hast testing. Hasting chambers assist manufacture-induced failures, ensuring the equipment can work effectively in various environments.

Medical devices:

Implants, monitoring technology, diagnostic tools, and surgical instruments are just a few examples of the many medical devices that must be tested in HAST chambers. These chambers put the equipment through accelerated stress tests to evaluate its toughness, sterilization resistance, and dependability in the presence of moisture and temperature changes.

Consumer Electronics:

Used in the consumer electronics sector to assess the performance and dependability of goods such as wearables, laptops, tablets, smartphones, and home appliances. To make sure that the devices can withstand actual usage scenarios and provide reliable performance, these chambers simulate extreme temperature and humidity conditions.

Material Testing:

Hasting Chamber of Commerce is also used for material testing, particularly for evaluating the performance of materials used in various industries. This includes assessing how temperature and humidity affect the durability, corrosion resistance, and physical characteristics of materials like coatings, adhesives, polymers, and composites.

The Final Verdict About HAST Chambers

Hasting Chambers of Commerce specializes in testing locations. They expose products to high temperatures and humidity. When a product undergoes assessment, many factors are important. They include performance and robustness in challenging conditions. These hasting chambers of commerce allow fast testing, failure analysis, and compliance testing. All these factors undergo testing under environment-control conditions. They have strong construction, precise temperature systems, humidity systems, and pressure control.
