Standards and accreditation
- UKAS 4413 and ISO/IEC 17025:2017
- The direct ten-page schedule names MS Testing as a trading division of Mariner Systems (UK) Ltd, issue 029 dated 11 December 2025, accredited to ISO/IEC 17025:2017 for the listed scope. Laboratory A and conditional off-site IPX5 at S are kept distinct. Separate live accreditation status was not verified.
- Marine testing context and listed method editions
- The homepage describes marine type-approval testing to IACS E10, EN60945 and class-society rules. The dated scope lists IACS E10:2022 and :2024 for relevant entries. Published website method editions and the direct schedule are separate sources. Confirm the required controlled edition and any approval process. Testing does not itself establish authority to grant a class approval.
- EMC product-standard restriction
- The schedule states that listed EMC product standards are accredited only to the extent that they call up the basic standards accredited within this schedule. Confirm every required basic method and the applicable product exclusions.
What to confirm with the facility
- The schedule repeats a main-address-only header, but its location table expressly allocates off-site environmental IPX5 testing to S, subject to suitability and contract review. The IPX5 method row is marked A and S. No wider off-site test service is inferred.
- Conducted-emissions EN 55022:2006 + A1:2007 excludes telecommunication ports, and EN 55032:2015 + A11:2020 excludes the antenna port. The listed EN 55011 conducted entry excludes Group 2 apparatus and grid-connected power converters. Listed EN 55011 radiated-emissions entries exclude Group 2 apparatus. Confirm the exact applicable product-standard entry.
- This is a selection from the ten-page schedule. Each chamber, frequency, field, voltage, pulse, inclination or mass condition belongs to its own entry. The thermal-shock and needle-flame rows do not print location codes. Confirm the required method, allocation and combination of conditions.
- Confirm equipment quantity, dimensions and mass, fixtures, operating modes, preparation, quotation, turnaround time, reporting and attendance or shipment arrangements directly.
