Overview - EN ISO 7439:2023 (Copper-bearing IUDs)
EN ISO 7439:2023 specifies requirements and tests for single‑use, copper‑bearing contraceptive intrauterine devices (IUDs) and their insertion instruments. Published in 2023 and adopted by CEN, this fourth‑edition standard supersedes EN ISO 7439:2015. It applies to non‑medicated, copper‑containing IUDs (single use) and excludes devices that are plastic‑only or whose primary purpose is drug (progestogen or other medicinal) release - although some clauses may be relevant to medicated IUDs.
Key topics and technical requirements
The standard defines design, testing and information requirements needed to demonstrate safe, effective performance. Major technical topics include:
- Intended clinical performance: guidance on clinical performance parameters, study duration, population, sample size, contraceptive effectiveness, expulsion and discontinuation rates, and investigation reporting.
- Design attributes: device shape, dimensions, tensile force (thread and component strength), stability, viscoelastic properties and X‑ray detectability.
- Materials: requirements and considerations for copper components, polymer bodies and any radiopaque additives (e.g., barium sulfate content and identification tests are referenced).
- Design evaluation and pre‑clinical testing: dimensional, mechanical and memory (elastic recovery) tests, plus pre‑clinical evaluations required prior to clinical use.
- Manufacturing, inspection and quality verification: processes for production control, sampling, and verification of lot consistency.
- Sterilization and packaging: requirements to ensure sterility, shelf‑life stability and protective packaging for single‑use devices.
- Labelling and information: mandatory labelling of primary/secondary containers, instructions for healthcare providers, and written information intended for the client post‑insertion.
Practical applications
EN ISO 7439:2023 is used to:
- Guide design and development of copper IUDs and insertion instruments to meet regulatory expectations.
- Define testing protocols for manufacturers to demonstrate mechanical integrity, sterility, dimensional accuracy and radiopacity.

ISO 7439:2023(E)
Introduction
Although every foreign object in the uterus exhibits a certain contraceptive effect, the method by
which copper-bearing contraceptive intrauterine devices (IUDs) function is by the continuous release
of copper ions. This interferes with some enzymatic functions, immobilizes sperm cells and inhibits
fertilization.
The IUD is a highly effective contraceptive device with a long history of safe use. It can be used for many
years, with a prompt return of fertility upon removal.
IUDs do not prevent sexually transmitted infections and condom use is recommended for those at risk.
IUDs containing copper are regarded as single use sterile medical devices implanted in the uterus.
These medical devices are inserted and removed by trained and competent health care providers.

4 Quality verification
Copper bearing IUDs should be manufactured within an integrated quality management system
conforming to ISO 13485.
NOTE For most countries and regions, this is a regulatory requirement.
For quality verification purposes, the sample size requirements and acceptance criteria specified in
Annex A shall be used. These requirements are based on ISO 2859-1.
The sampling plans have been simplified to take into account typical industry lot sizes, the specific
characteristics of IUDs and the nature of the manufacturing processes used to produce them. The
sample sizes and acceptance criteria have been selected to provide an acceptable level of consumer
protection taking into account the costs of sampling and testing. In addition to verification testing, it
is strongly recommended that manufacturers conduct process validation and capability studies, and
adopt statistical process control procedures such as the use of control charts to ensure acceptable
product quality.
The sampling and acceptance criteria given in Annex A are intended to cover the following situations:
a) continuing production of lots within a stable manufacturing environment;
ISO 7439:2023(E)
b) the assessment of isolated lots (e.g. fewer than 5), for example when purchasers wish to conduct
confirmatory testing on a limited number of lots, when production is interrupted or intermittent,
or for surveillance testing.
In addition, the rules for switching between normal and tightened inspection in ISO 2859-1 have been
adopted to provide greater level of consumer protection should the quality of a manufacturing process
deteriorate. These rules are applied as follows:
— Normal inspection – the specified sample sizes for normal inspection apply at the start of production.
Normal inspection continues to apply unless two nonconforming lots are found in any sequence of
5 or fewer lots tested. If this occurs the number of samples used to assess the conformity for future
lots shall be increased to those specified for tightened inspection.
— Tightened inspection – the specified sample sizes for tightened inspection shall apply until a sequence
of 5 lots have been accepted. Following the acceptance of 5 sequential lots, the manufacturer may
return to the sample sizes for normal inspection.
The switch to reduced inspection has not been adopted for the testing of copper bearing IUDs. Switching
to smaller sample sizes is not considered acceptable given the potential for increased consumer risk
because of the small sample sizes specified under normal inspection for many of the tests.
5 Intended clinical performance
