SIST EN 2591-6316:2004 is the Slovenian adoption of the European Standard EN 2591-6316 for aerospace electrical and optical connection elements. It specifies a test method for determining the effect of ozone on optical connection elements, including permanent connections, and fibre optic couplers. The standard is intended for use together with EN 2591-100.

What does SIST EN 2591-6316:2004 specify?

SIST EN 2591-6316:2004 specifies how to assess ozone resistance in optical connection elements used in aerospace applications. In practice, it tells users how to prepare specimens, carry out the ozone conditioning, and then check the optical condition of the parts afterwards.

The document is organized into:

• Clause 1 - Scope
• Clause 2 - Normative references
• Clause 3 - Preparation of specimens
• Clause 4 - Apparatus
• Clause 5 - Method
• Clause 5.1 - Procedure
• Clause 5.2 - Final measurements and requirements

This structure matters because the standard is mainly a test method reference. A laboratory or supplier can move through the clauses in order to prepare the samples, use the right equipment, run the exposure, and perform the required post-test checks.

What are the key requirements of SIST EN 2591-6316:2004?

The main requirement is to use the method to determine the effect of ozone on the specified optical connection elements. The standard is not a design document; it is a test method, so its value is in how it guides preparation, conditioning, and verification.

Specimen preparation follows EN 2591-316

Clause 3 says specimens shall be prepared as specified in EN 2591-316. That means users do not invent their own sample preparation for this part - they follow the preparation rules from the referenced ozone resistance method.

Clause 3 also says the technical specification should state certain details when applicable. These include the type and length of cable/fibre, the maximum value of insertion loss, and the initial measurements and requirements. In practice, this is the information a buyer, engineer, or test lab needs to define before testing starts.

Apparatus and procedure are taken from EN 2591-316

Clauses 4 and 5 direct the user to EN 2591-316 for the apparatus and the procedure. This means the detailed ozone test setup is not repeated here, and the user must apply the equipment and conditioning method defined in that referenced part.

Final checks are mandatory after conditioning

Clause 5.2 requires final measurements and requirements after conditioning. The document names two checks:

• EN 2591-6101 - visual examination
• EN 2591-601 - insertion loss

In practice, this means the test does not end with ozone exposure. The sample must also be inspected for visible damage and remeasured for optical loss so the result reflects both appearance and performance.

EN 2591-100 remains the general companion standard

The scope states that this standard shall be used together with EN 2591-100. That matters because EN 2591-100 provides the general framework for the EN 2591 test methods, while this part adds the ozone resistance method for optical elements.

What terms does SIST EN 2591-6316:2004 define?

• Optical connection elements - the optical parts covered by the test method, including the elements that carry or join optical signals.
• Permanent connections - optical connections included in the scope where the connection is intended as a lasting arrangement.
• Fibre optic couplers - components that couple fibre optic paths and are specifically included in the test scope.
• Specimens - the test samples prepared and exposed according to the method before final checks are made.
• Insertion loss - the optical loss checked after conditioning, using the method in EN 2591-601.
• Visual examination - the post-test inspection used to look for visible effects of ozone, as referenced in EN 2591-6101.
• Ozone resistance - the property being assessed by this test method: how the optical element responds to ozone exposure.

Who uses SIST EN 2591-6316:2004?

SIST EN 2591-6316:2004 is used by aerospace manufacturers, test laboratories, and quality teams working with electrical and optical connection elements. Engineers use it to define how to qualify a product for ozone exposure, while buyers and suppliers use it to agree on what has to be tested and recorded.

It is also relevant for organizations that prepare technical specifications for optical connection elements and fibre optic couplers. The standard gives them a common test language for initial measurements, exposure, and final acceptance checks.

What changed in SIST EN 2591-6316:2004 from the previous edition?

SIST EN 2591-6316:2004 is identified as identical to EN 2591-6316:2001.

Which standards are used with SIST EN 2591-6316:2004?

• EN 2591-100 - the general standard for aerospace electrical and optical connection test methods; the scope says this part shall be used with it.
• EN 2591-316 - provides the specimen preparation, apparatus, and procedure referenced for this ozone resistance test.
• EN 2591-601 - provides the insertion loss measurement used in the final checks.
• EN 2591-6101 - provides the visual examination used in the final checks.

What does the SIST EN 2591-6316:2004 document contain?

SIST EN 2591-6316:2004 contains a short ozone resistance test method for optical connection elements. It sets the scope, points to the general and related EN 2591 parts, and gives the sequence for preparing specimens, using the required apparatus, and carrying out the method.

The practical content is mostly in the references to other parts. The document tells the user where to find specimen preparation, how to perform the exposure, and which final inspections and optical measurements must follow the test.

For a laboratory, the document is useful as a test instruction. For a specification writer, it shows which details need to be stated before testing, especially cable or fibre type and length, maximum insertion loss, and any initial measurements.
