Marine Immersion Label Testing | BS 5609
Labels are typically used for identification, warning and instruction applied to drums containing chemicals. BS 5609 is used to ensure the performance of labels used in marine environments.
BS 5609 Understanding the 2024 Revisions
What is BS 5609?
BS 5609 is a British Standard that ensures printed, adhesive labels hold up in tough marine environments. It measures adhesive performance, print permanence and abrasion resistance, indicating whether the unprinted labelstock and the printed facestock will remain legible and intact, even in the harshest conditions.What do sections 2 and 3 of BS 5609:2024 cover?
Sections 2 and 3 of BS 5609:2024 outline how to assess the performance of both unprinted and printed stock in various marine environments. Section 2 covers testing unprinted labelstock for conditions such as marine immersion, weathering, temperature cycling, and abrasion. Section 3 focuses on assessing the performance of the printed facestock, including print key adhesion, abrasion, and artificial weathering.At Smithers we work closely with clients to conduct BS 5609 testing using specialist, purpose-built facilities at our in-house UK laboratories.
When did BS 5609:2024 come into effect?
The 2024 version of BS 5609 came into effect on 31 December 2024. This updated BS 5609:1986, which will be withdrawn on 31 December 2030, and ensures the Standard is in line with modern industry requirements.How has BS 5609 changed?
This is a significant revision of the previous standard, which now separates the requirements for adhesive-coated facestock from those for printed label materials. The main changes include:Separate testing and certification of Section 2 (unprinted label stock) and Section 3 (printed facestock), which was not previously possible.
Previously, Section 3 approvals could only be given by testing printed labels made from Section 2-approved labelstock. Now both can be passed individually.
Labels that have been certified to Section 2 of BS 5609:1986 only need to be tested on HDPE.
HDPE is now included as a mandatory test surface, reflecting the growing use of plastics in the industry. Aluminium remains as a mandatory test material.
Labels already certified under Section 3 of BS 5609:1986 will not need retesting.
Section 3 determines the performance of printed facestock for print key adhesion, abrasion and artificial weathering.
