All the components that make up a refrigeration and air conditioning system, materials are highly effective and reliable determinants of the system. Wrought copper tubes are slowly becoming the most widely used ones because they have impressive characteristics such as high heat transfer coefficient, immunity to corrosion, and strength. Standard steel tubes are components used in HVAC systems to help with proper heat transfer and proper passing of refrigerant. In India, the Bureau of Indian Standards (BIS) has established guidelines under IS 10773:1995 as a code of practice for the control of the quality and performance of wrought copper tubes that should meet rigorous sector standards.
Hence this blog highlights the following; manufacturing of the wrought copper tubes for refrigeration/air conditioning, performance requirements and measures, testing methods, laboratory standards, labeling for products, and the documents needed for certification by BIS. Today, due to understanding these elements, manufacturers and consumers alike can realize the importance and role of quality assurance in providing an optimized performance and safety of these systems. Read on to learn more about how we attempt to demystify this essential component of new-age HVAC technologies; the wrought copper tubes.
BIS Registration Sample
Wrought copper tubes are widely used in refrigeration and air conditioning systems because of such factors as conductivity, corrosion, and hardness. These tubes are manufactured from high-purity copper, typically conforming to the specifications outlined in the Bureau of Indian Standards (BIS) under IS 10773:1995. This standard provides a certain set of overall performance characteristics that the copper tubes for use in HVAC equipment must demonstrate.
The unique properties of wrought copper make it an ideal choice for various applications, including:.
The manufacturing process of wrought copper tubes involves several key steps:
With this manufacturing process, the tubes conform to high-quality standards for use in refrigeration and air conditioning.
Wrought copper tubes must adhere to specific performance requirements as outlined in IS 10773:1995. These include:
The testing methods for wrought copper tubes include:
Tensile Tests: Estimating strength by pulling samples to the rupture point detects the strength or load-bearing capacity of a material.
Bend Tests:Assessing ductility through bend samples in a way that is determined by certain angles.
Ultrasonic Testing:Establishing internal defects without compromising on the tube.
Hydrostatic Testing: Another test that is done involves placing the tube in water and pressurizing it to try and check if there are leaks.
Visual Inspection:Carrying out a detailed check of external surface quality for the signs of defects such as cracks or pits.
They also provide guarantees that only high-quality products get into the market so as to guarantee safety and reliabilityui.
To conduct testing on Wrought Copper Tubes for Refrigeration and Air Conditioning Purposes effectively, laboratories must adhere to specific requirements:
Labeling and markings are fundamental requirements of BIS standards regarding Wrought Copper Tubes for Refrigeration and Air Conditioning Purposes. Each product must include:
The following are the documents required for BIS Certification:
| General Documents | Technical Documents |
|---|---|
| Business License | Plant Layout |
| Trademark License | List of Manufacturing Equipment |
| Application Form | Manufacturing Process Flow Chart |
| Authorization Letter | Product Literature |
| Laboratory Test Reports | List of testing equipment and machinery |
| MSME certificate | Productβs technical Specification |
| List of calibration certificate |
The BIS certification process for Wrought Copper Tubes for Refrigeration and Air Conditioning Purposes involves several steps:.
Applications are filled including relevant documents that outline the production processes of the manufacturers.
A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.
The samples from the production batches are analyzed at the BIS-accredited laboratories.
As a result of the evaluation of these facilities and products, BIS grants permission to the manufacturers to use the ISI mark on their products.
To sustain the standards practice, normal assertions are carried out.
This is a process that manufacturers need to understand so that they can get an efficient certification.
Importance of BIS Certification
BIS certification is crucial for several reasons:
Conclusion
Wrought copper tubes are widely used tubing materials in refrigeration and air conditioning systems because of their high conductive coefficient, corrosion resistance, and mechanical strength. Compliance with IS 10773:1995 ensures these tubes offer the best performance standards as vital for a reliable stream in HVAC applications.
Manufacturers are expected to follow strictly the manufacturing processes and test the products rigorously, have their laboratory accredited, and properly label their products. Besides improving market appeal, BIS certification gives the customers confidence in the product as being safe to use.

IS 10773 is the standard that describes the crucial characteristics of wrought copper tubes for refrigeration and air conditioning systems in India.
BIS certification safeguards customers since it guarantees that specific products conform to national standards with regard to safety, quality and /or performance.
Most wrought copper tubes are made from copper alloy C12200 with high copper content

They've been very helpful in our registration with ICEGATE. It was a small thing with a small amount paid which somehow escalated to a very painful procedure. Never did they say "You've only paid so much. It's too much effort for us.".
Very pleased with their service. Prompt, professional and great communication. Definitely recommend. Special mention for Ms. Razia - she handled our case.
Professional Utilities is fully professional in their work, Rates are too low and genuine. Services and satisfaction are high so I highly recommended Professional Utilities.
They are one of the most genuine and reasonable people. I applied for lmpc certificate through them and they charged me a very nominal amount as compared to what other firms asked .
