BS EN 489 is a European standard on district heating pipes that discusses the best procedures and specifications required for manufacturing high-quality Joint casing assemblies and thermal insulation for hot water networks. BS EN 489‑1 is the first part of a series of documents on district heating pipes. BS EN 489‑1 specifies requirements and test methods for joints between adjacent factory-made pipe, and/or fitting and/or valve assemblies for buried hot water networks by EN 13941-1.
BS EN 489‑1:2019 on district heating pipes is relevant to:
District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating.
BS EN 489‑1 navigates you through the general requirements for the joint, joints of single and twin pipes, welding of steel service pipes, polyurethane (PUR) foam thermal insulation, and various test methods.
As a user of BS EN 489‑1, you can be ensured of all the requirements and test methods of joints between adjacent factory-made pipe, fitting, and valve assemblies. BS EN 489‑1 highlight tried and tested methods that will help users achieve precision in terms of products specification. BS EN 489‑1 assist you in prolonging the service life for joints between adjacent factory-made pipe, fitting and valve assemblies for buried hot water networks
BS EN 489‑1:2019 supersedes BS EN 489:2009, which is withdrawn.
The first edition of EN 489 was approved in 1994 and updated in 2003 and 2009. The main areas of this revision are the following:
