Plastic coated copper tube is a popular product in the current market due to its excellent properties. Not only is it corrosion resistant and electrically insulated, but it is also extremely durable, meaning that it is suitable for a wide range of applications. In order to ensure the quality of the plastic coated copper tube, it is important to abide by the standards set out in the T451-2002 specification. This specification covers a wide range of areas, from the requirements, testing methods, and inspection rules to the marking, packing, transportation, storage and other related requirements. According to the specification, plastic coated copper tubes can be divided into two categories, polyolefin coatings and polyvinylchloride (PVC) coatings. Both categories must adhere to the technical requirements set out in the standard, such as heat aging resistance, internal pressure, low temperature impact, salt spray resistance, boiling, tensile strength in cold state, and tensile strength in hot state tests. Furthermore, in addition to the tests mandated by the conformance the related standards, plastic coated copper tubes must also fulfill the other requirements set out, such as environmental protection, non-toxicity, and incombustibility.
Once the tests have been completed and the requirements fulfilled, it is important to ensure that the plastic coated copper tube is packaged properly and transported carefully. According to the T451-2002 specification, the tube should be packed in accordance with the guidelines set out in GB/T9468-1994 and the markings must be done in compliance with GB/T13022-1991. Furthermore, the transportation should be handled with care to avoid any mechanical damage or rupturing. Upon arrival at its destination, the plastic coated copper tube should be stored in a dry location away from extreme temperatures (not less than -5℃ and not more than35℃), and away from any form of moisture.
Last but not least, it is important to note that the aggrieved party has the right to make a checking request to the manufacturer within 15 days of receiving the product. The manufacturer must then return an explanation letter within 15 days of receiving the request including the specific checking results, analyzed causes and proposed measures. This regulation is put in place to help ensure the quality of the plastic coated copper tube, and allow for better customer satisfaction.
In conclusion, the specification for the plastic coated copper tube, T451-2002, is an essential guide to ensuring the quality of the product. It is important to note that the specification covers a wide range of aspects, from the requirements and testing methods, to the packing and transportation. Furthermore, in order to ensure customer satisfaction, there are some additional regulations in place, such as the aggrieved partys right to request a checking from the manufacturer. Following the guidelines set out in the T451-2002 specification can help to ensure the quality of the plastic coated copper tube, and keep customers happy.
