SIST EN 3660-013:2008 is the Slovenian adoption of EN 3660-013:2008, a CEN European Standard prepared by ASD-STAN for the aerospace series. It specifies a style A, straight, unsealed cable outlet with cable tie strain relief for circular and rectangular electrical and optical connectors, so designers, manufacturers, test labs, and buyers can specify the same product form and verify it the same way.

What does SIST EN 3660-013:2008 specify?

SIST EN 3660-013:2008 defines one product family of cable outlets, style A, for use with the associated connector standard EN 3660-002. It also sets the temperature classes, the dimensional interface, the material and finish options, the test programme, and the designation and marking rules.

Clause	What it covers
1	Scope
2	Normative references
3	Terms and definitions
4	Characteristics
5	Designation
6	Marking
7	Technical specification

The scope limits use to associated electrical connectors from EN 3660-002 and to the temperature ranges for Class N and Class W. In practice, that tells the reader which connector family and which environmental range the part is intended to match.

What are the key requirements of SIST EN 3660-013:2008?

SIST EN 3660-013:2008 is mainly a dimensional and verification standard. Clause 4 controls the physical interface, the material finish, installation torque, strength torque, and the test plan that proves the part is suitable for aerospace use.

Fit, size, and interface

Clause 4.1 defines the shell sizes, dimensions, mass, thread form, and the location of the cable tie or lacing area. Figures 1 to 3 and Table 1 show the envelope and the spacer pad, which matters because these parts must fit the intended connector and leave enough room for the cable restraint method.

Clause 4.2 links the cable outlet to the associated connector interface in EN 3660-002 and to the standard AS85049 interface. Table 2 and Figures 4 and 5 define the teeth count and the interface diameters, so procurement and inspection can confirm that the rear accessory will mate and lock correctly.

Material, finish, and installation

Clause 4.3 assigns the material and finish by class: aluminium with electroless nickel for Class N, and aluminium with olive drab cadmium plate for Class W. The spacer is fluorosilicone and green, which matters when matching environmental performance and identifying the approved build.

Clause 4.4 gives installation torque values for assembly only, while Clause 4.5 gives coupling thread strength torques for test purposes. In practice, one set is for tightening during installation and the other is for proving the thread can withstand the required mechanical load.

Verification and qualification

Clause 4.6 ties verification to Table 5 and to EN 3660-001. The test matrix covers visual examination, dimensions and mass, housing continuity, surface transfer impedance, temperature endurance, rapid temperature change, environmental exposure such as salt mist, sand and dust, low pressure, ozone, and mechanical checks such as shock, vibration, endurance, mating and unmating forces, rear accessory strength, locking wire hole strength, and magnetic permeability.

Several tests are marked for variant A only, including mould growth, fluid resistance, and flammability. That helps a buyer or test house know which checks apply to the selected version before qualification starts.

Identification and documentation

Clause 5 defines the designation format, combining the description block, the standard reference, the material and finish class, the shell size, and the variant code. This is important for ordering and traceability because the part number carries the exact build definition.

Clause 6 points the marking requirement back to EN 3660-001 and Figure 1, and Clause 7 points the technical specification back to EN 3660-001. Together, these clauses show that this part standard works as a product definition built on the parent technical specification.

What terms does SIST EN 3660-013:2008 define?

Clause 3 uses the terms and definitions from EN 3660-001. The key terms in this part are:

• Cable outlet - the rear accessory on a connector that provides cable exit and strain relief.
• Style A - the product style covered by this part, identified as straight and unsealed.
• Class N - the version with aluminium and electroless nickel finish, used in the higher temperature range.
• Class W - the version with aluminium and olive drab cadmium plate finish, used in the lower temperature range.
• Spacer pad - the fluorosilicone insert shown in Figure 3 and used in the variant identified in the designation example.
• Shell size - the size code used in the dimensional tables and designation, such as 08 to 24.
• AS85049 interface - the interface pattern used for compatibility checking in Clause 4.2.2.

Who uses SIST EN 3660-013:2008?

SIST EN 3660-013:2008 is used by aerospace connector and accessory manufacturers, harness and system integrators, test laboratories, quality teams, and procurement staff. They use it to specify a cable outlet, check fit and finish, run qualification tests, mark the product, and write purchase or inspection requirements for connector back-end accessories.

Which standards are used with SIST EN 3660-013:2008?

SIST EN 3660-013:2008 depends on these referenced and companion documents:

• EN 2591 - provides the test methods used in the verification table, including the thread strength torque test in EN 2591-420.
• EN 3660-001 - gives the technical specification, terms and definitions, marking basis, and qualification framework for cable outlet accessories.
• EN 3660-002 - identifies the associated electrical connector(s) that this cable outlet is intended to fit.
• AS85049 - provides the connector accessory general specification used as an interface reference in Clause 4.2.2.

What does the SIST EN 3660-013:2008 document contain?

The document contains dimensioned drawings, interface figures, and tables for shell sizes, mass, thread data, torque values, and interface teeth counts. It also contains the material and finish definition, a designation example, and a test matrix that links product verification to specific EN 2591 methods.

For readers doing design or inspection, the most useful parts are Figures 1 to 5 and Tables 1 to 5. Those pages tell you what to measure, what to test, and how to identify the part without reproducing the normative values here.
