HVAC testing

1、 Compatibility testing of HVAC system materials

Understanding the chemical stability of your product will help you avoid system failures and limit warranty claims.

By measuring the compatibility of refrigerants and lubricants, we can help you understand how a new component will react in your HVAC system.

Whether you are producing an HVAC system or one of its components, chemical compatibility testing can help you record the reliability of your product. The products we test include gaskets, elastomers, seals, O-rings, lubricants, optional refrigerants, desiccants, dyes, cutting oils, cleaning agents, and process and performance enhancing liquids.

Standard testing methods

ASHRAE 97 and 99- Sealed glass tube method for testing the chemical stability of materials used in refrigeration systems

SAE 2297- UV Leak Detection: Stability and Compatibility of Fluorescent Leak Detectors for Refrigerants Used in Automotive R-134a Air Conditioning Systems

Stability and compatibility standards for additives or embedding materials used in SAE-R-134a automotive air conditioning systems

UL 984- Sealed Refrigeration Motors - Compressors

Based on the test results, our well-trained chemists will be able to identify components that exhibit adverse chemical reactions. Our employees can provide guidance, explain test results, discuss maintenance history, or propose corrective measures at any time. When collaborating with NormalTCI, you already have a wealth of data, and through material compatibility testing, your product will be able to achieve the best combination of construction materials.

Accelerated aging testing methods (such as ASHRAE 97, SAE J 1662, SAE J 2299, or UL 984) aim to measure the chemical effects of the target material on the system over its standard lifespan.

After completing accelerated aging, we will measure your sample and quantify many properties:

● Tensile strength and elongation

● Chlorine content

● Dissolve metals

●Fluorine content

● Meteorological chromatography

● Gas chromatography/mass spectrometry

● Infrared analysis

● Liquid chromatography

● Total acid value

● Appearance inspection

● Copper plating

● Corrosion

● Color change

● Microscope

2、 Quality and performance indicators for HVAC/R equipment

Quality and performance labels will help you demonstrate your commitment to the quality of HVAC/R equipment.

There are many situations that can occur during the lifecycle of a product: the more you master the product lifecycle, the better your product will be, and you will achieve greater sales success. Performance testing provides you with the knowledge you need to achieve unprecedented levels of control. From design engineering/evaluation to prototype testing/validation and even finished product comparison/benchmark testing, NormalTCI Nuomo Testing can effectively and economically provide independent, unbiased third-party performance testing within one product cycle, regardless of location. NormalTCI has testing laboratories located around the world and over 60 years of experience in the HVAC/R industry, making it your comprehensive one-stop performance testing service company.

Quality Mark

The comparison and benchmark testing of NormalTCI can help you make decisive choices in design, select the right supplier, choose materials, or determine whether your product is better or more durable than competitors.

● Reduce warranty costs: Performance testing not only proves your product, but also helps you predict warranty costs. Conversely, this enables you to make more accurate warranty expense plans.

● Reduce costs while ensuring quality: Performance testing can compare costs and help you maintain quality. You can also validate your supply chain by testing and comparing various components.

●Establish brand trust and loyalty: When testing your product's marketing proposition, you can have independent third-party laboratory evidence to prove that your marketing proposition far exceeds your promises. You will have convincing evidence to prove to your market.

How to use quality and performance indicators

If you meet or exceed the benchmark, you can use the NormalTCI quality and performance logo in advertisements, websites, or other marketing materials to provide strong evidence for your product. These five benchmark quality tests include:

Durability

Assess the range of conditions under which a certain product can cope with and continue to function effectively.

performance

Evaluate the performance of a product's main functions and features under normal use

Life cycle

Under ideal conditions, the basic functional usage time of the product reaches the specified end of life (the lifespan of the product during normal use).

Practicality

Ease of operation under normal conditions.

Workmanship

Testing the physical characteristics of a certain product as an indicator for evaluating high-quality production and processing techniques.

Check/Plus performance

In addition to the five benchmark tests listed above, specific manufacturer claims can also be tested through a sixth test called Checkplus performance. Once certified by NormalTCI, these statements can be described in advertisements, retail outlets, and on products and packaging to highlight the differences of the product compared to competitors.

Accelerated Stress Test (AST)

Accelerated stress testing is a series of tests used to quickly detect actual usage faults. AST has compressed many regular tests by up to 50% while eliminating other tests. The AST results ensure the reliability of the product and guarantee fewer warranty claims.

Declaration verification

Is your product faster, better, and simpler to use? When you obtain independent verification of performance statements that highlight the differences of your product, you gain reliable information for marketing and confirmation of internal testing and data supported by industry associations, as well as a way to prove that your statements outperform competitors.

Comparative testing

By comparing your product with competitors' products, you will be guided on the strengths of your product and the weaknesses of your competitors.

Durability/Endurance Testing

Ensure that the service life of your product meets consumer expectations, complies with product statements, and meets warranty parameters.

Energy certification

Prove that your product meets voluntary energy efficiency standards by ensuring that it largely complies with the California Energy Commission, Natural Resources Canada (NRCan), EU Energy Labeling, ErP Directive, and other requirements.

Environmental Testing

Test for wind, rain, UV exposure, or almost all other environmental conditions. Environmental testing ensures that your product functions effectively in every environment, at the time and place it should function.

Material Testing

Measure the physical, chemical, and mechanical properties of plastics, fabrics, metals, glass, and other materials. Material testing allows you to make the best design or procurement choices based on performance, durability, and customer satisfaction.

Electrical testing

Understand how your product performs under various electrical conditions. Measure the electrical functionality of product systems, subsystems, and components. The scope of electrical testing includes current, voltage, power consumption, performance HALT/HASS、 Data collection, etc.

Acoustic testing

Verify the acoustic and airflow performance of the product - including mechanical equipment and accessories (heating, ventilation, and air conditioning equipment, fans, hair dryers, etc.).
