What is BS EN 489‑1 - District heating pipes about?
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.
Who is BS EN 489‑1 for - District heating pipes?
BS EN 489‑1:2019 on district heating pipes is relevant to:
- Manufacturer of pipe, fitting, valve assemblies for buried hot water networks
Why should you use BS EN 489‑1- District heating pipes?
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
What’s changed since the last update?
BS EN 489‑1:2019 supersedes BS EN 489:2009, which is withdrawn.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:
- Ageing resistance test for PUR foam has been removed
- Requirements to plugs have been added
- Requirements and test methods for PUR foam properties are back in EN 253
- Requirements for marking of joints have been added
- Preparation of test specimen, under supervision of the test institute, has been added
