What is BS EN 1971‑1 - Eddy current test about?
BS EN 1971 is a European standard on copper and copper alloys that discusses the criteria for eddy current testing. BS EN 1971‑1 is the first part of a series of documents on seamless round copper and copper alloy tubes. BS EN 1971‑1 specifies a procedure for the eddy current test with an encircling test coil for measuring defects on the outer surface of seamless round copper and copper alloy tubes.
The choice of the method for eddy current test:
- With an encircling test coil on the outer surface according to EN 1971‑1 or
- With an internal probe on the inner surface according to EN 1971‑2
is at the discretion of the manufacturer if there are no other agreements between the purchaser and the supplier.
NOTE: The eddy current test method(s) required, together with the size range and acceptance level, are defined in the relevant product standard.
Who is BS EN 1971‑1- Eddy current test for?
BS EN 1971‑1 on copper and copper alloys is relevant to:
- Manufacturer of seamless round copper and copper alloy tubes.
- Laboratories and research centers
Why should you use BS EN 1971‑1- Eddy current test?
Eddy current testing is a non-destructive testing (NDT) inspection method used for a variety of purposes, including flaw detection, material and coating thickness measurements, material identification, and establishing the heat treatment condition of certain materials.
BS EN 1971‑1 navigates you through the detection of local discontinuities by encircling coils systems, detection of non-local discontinuities by encircling coils systems with lower detection levels, and other test methods.
With obedience and compliance to BS EN 1971‑1, you can detect potential leaks and serious defects in seamless round copper and copper alloy tubes. With the guidance of BS EN 1971‑1, you can detect material inhomogeneities and their positions throughout the length of tubes. The eddy current signals of material inhomogeneities are compared with reference signals of artificially produced test defects. It is possible to identify these inhomogeneities on the inner and outer surfaces as well as within the tube wall. Overall with BS EN 1971‑1, you can be ensured that the products consistently meet and exceed quality assurance targets.
