SIST EN 61300-2-15:2008
(Main)Fibre optic interconnecting devices and passive components - Basic test and measurement procedures -- Part 2-15: Tests - Torque strength of coupling mechanism
- Abstract
This part of IEC 61300 applies an overload torque to twist-type coupling mechanisms. It is applicable to threaded or bayonet-twist type coupling mechanisms. It can be used to ensure that the coupling mechanism of a connector set or connector-device combination will withstand the torsional loads likely to be applied during normal service. Specific technical changes from the previous edition include reexamination of the pre-conditioning and rewriting of the entire composition according to the latest IEC Directives.

SIST EN 61300-2-15:2008 is the Slovenian adoption of EN 61300-2-15:2008, which adopts IEC 61300-2-15:2008 without modification. It specifies a torque strength test for twist-type fibre optic coupling mechanisms, including threaded and bayonet-twist types. The test checks whether a connector set or connector-device combination can withstand the torsional loads expected in normal service.
What does SIST EN 61300-2-15:2008 specify?
SIST EN 61300-2-15:2008 specifies an overload torque test for fibre optic interconnecting devices and passive components. It focuses on the coupling mechanism, so the reader knows the document is about mechanical strength under twisting load, not optical performance.
The document is organized into seven clauses:
- Scope
- Normative references
- General description
- Apparatus
- Procedure
- Severity
- Details to be specified
It also includes one normative annex.

What are the key requirements of SIST EN 61300-2-15:2008?
SIST EN 61300-2-15:2008 requires a smooth overload torque to be applied to a mated connector set or connector-device combination. In practice, the test is meant to simulate twisting loads without introducing impact or bending, so the result reflects the strength of the coupling mechanism itself.
Apparatus and set-up
The standard calls for a test arrangement that can apply torque manually or automatically while holding the adapter or device in place. The specimen holder must not rotate, but it must be able to move enough to keep the parts aligned.
The coupling shall transfer torque orthogonally to the interface, without a bending moment. The torque applicator and gauge shall have a range no more than three times the required test torque, and the gauge accuracy shall be within 10 % of the applied value. In practice, that means the measuring equipment must be chosen so the reading is meaningful, not overly coarse.
Preparation, pre-conditioning and loading
Specimens are to be mated according to the manufacturer’s instructions. For screw-type couplings, the coupling torque is set with a torque wrench to the proper value before the overload test begins.
Unless another specification says otherwise, specimens are pre-conditioned for 2 h at the standard test conditions in IEC 61300-1. The torque is then applied smoothly at a nominal rate, with no impact loading, and maintained for at least 15 s unless a different duration is specified.
Post-test examination and severity
After the load is removed, the specimen is examined in accordance with IEC 61300-3-1 unless another specification gives different instructions. The check looks for cracking, bending, permanent deformation, and any other damage that could impair function.
Clause 6 states that the severity depends on the applied torque and its duration, both of which are given in the relevant specification. It also lists preferred non-mandatory overload torques of 0.4 N m, 0.6 N m and 0.8 N m, which helps the user choose a test level when defining a product requirement.
What must be specified for a product test
The relevant specification shall state the torque level, the required coupling torque, the load duration if it differs from 15 s, any alternative pre-conditioning, recovery procedure, specimen state, initial and final examinations, in-test checks if needed, deviations from the procedure, and additional pass/fail criteria. That is the information a manufacturer, lab, or buyer needs to turn the standard method into a product-specific test.
What terms does SIST EN 61300-2-15:2008 define?
- Coupling mechanism - The part that locks or joins the connector so the torque test can assess its resistance to twisting.
- Threaded coupling mechanism - A coupling that uses threads, so torque is applied through screw action and can be checked for overload strength.
- Bayonet-twist type coupling mechanism - A coupling that locks by a twist-and-lock motion, which the standard also covers.
- Pre-conditioning - The conditioning step before testing, here done at standard test conditions unless another requirement applies.
- Specimen - The item under test, such as a connector adapter, switch, attenuator, or similar device.
- Torque applicator and gauge - The tool and measuring device used to apply and read the torque during the test.
- Mated connector set - Two connected parts tested together to see whether the coupling survives the applied twisting load.
Who uses SIST EN 61300-2-15:2008?
SIST EN 61300-2-15:2008 is used by manufacturers of fibre optic connectors and passive components, by test laboratories, and by quality or compliance teams that need a repeatable torque-strength check. Buyers and specifiers also use it when they want a supplier to prove that a coupling mechanism can survive normal handling and service loads.
What changed in SIST EN 61300-2-15:2008 from the previous edition?
SIST EN 61300-2-15:2008 supersedes SIST EN 61300-2-15:1999 and the first IEC edition published in 1995. The stated technical changes are a reexamination of the pre-conditioning and a rewrite of the whole document to follow the latest IEC Directives.
Which standards are used with SIST EN 61300-2-15:2008?
SIST EN 61300-2-15:2008 uses IEC 61300-3-1 for the post-test visual examination, so the user has a defined method for checking damage after torque loading. It also refers to IEC 61300-1 for the standard test conditions used during pre-conditioning, which matters because the starting condition of the specimen affects the result.
What does the SIST EN 61300-2-15:2008 document contain?
The document contains a concise test method, not a product design specification. It gives the general test principle, the required apparatus, an example torque-tester figure, and the step-by-step procedure from specimen preparation through post-test examination.
It also gives the severity concept and the items that the relevant product specification must define. Annex ZA provides the European mapping of the referenced international publication.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance
