SIST EN 2267-008:2006

SIST EN 2267-008:2006 is the Slovenian standard identical to EN 2267-008:2005. It specifies UV laser printable electrical lightweight cables of the DM family for aircraft on-board electrical systems, for operating temperatures from -55 °C to 260 °C. The standard also allows -65 °C where a cold test shows it is acceptable, and it requires markings that comply with EN 3838.

What does SIST EN 2267-008:2006 specify?

SIST EN 2267-008:2006 specifies the product characteristics for DM family electrical cables used in aircraft. It is organized into 10 clauses covering scope, references, terms, materials and construction, required characteristics, quality assurance, designation, marking, packaging and delivery, and the technical specification.

In practice, this means the document tells suppliers and users what the cable is made of, how it is identified, which tests it has to pass, and how it is supplied. The main data for sizes and performance are given in Tables 1 to 3.

What are the key requirements of SIST EN 2267-008:2006?

Materials and construction

SIST EN 2267-008:2006 requires copper or copper alloy conductors nickel plated according to EN 4434 code D. The insulation build-up uses a polyimide tape first layer with fluorocarbon coating, then one or two PTFE tapes, with overlap rules given in Table 1. For single-core cable, the outer insulation tape has to accept UV laser printing.

This matters because the conductor material, plating, and insulation stack determine electrical performance, mass, and resistance to heat and handling during installation.

Size codes and dimensional data

SIST EN 2267-008:2006 uses size codes linked to nominal section, closest AWG, linear resistance at 20 °C, outside diameter, and mass in Table 2. Clause 4.3 also points to EN 2267-002 for the number of cores, and clause 4.4 points to EN 2267-002 for core colour coding.

For a buyer or harness designer, this is the table to use when selecting a cable size that fits the available space and meets current-carrying and weight targets.

Required characteristics and test methods

SIST EN 2267-008:2006 ties its performance requirements to EN 2084 and EN 3475-100, and Table 3 lists the applicable tests. Key points include overload resistance, thermal ageing, cold bend at -65 °C, thermal shock, flammability, thermal endurance, humidity resistance, abrasion, torsion, plating checks, arc resistance, strippability, flexibility, contrast, and UV laser markability.

This means qualification and routine verification depend on a defined test set, not on general product description alone. Table 3 gives the temperatures, times, forces and pass criteria that laboratories and quality teams have to use.

Marking, designation, and supply

SIST EN 2267-008:2006 requires markings that comply with EN 3838 and identifies the cable with a designation built from the standard number, number-of-cores code, nominal section code, and colour-coding code. Clause 7 gives the format and an example designation. Clauses 8 to 10 point to EN 2267-002, EN 2084 and EN 2235 for marking, packaging, delivery lengths and the technical specification.

In practice, this helps procurement, inspection and traceability teams order the right cable, check the received product, and keep markings readable through service and handling.

Quality assurance

SIST EN 2267-008:2006 sends quality assurance to EN 9133. That links the product standard to the aerospace qualification procedure for standard parts.

For suppliers, this is the route for demonstrating that the cable family is controlled and qualified in an aerospace context.

What terms does SIST EN 2267-008:2006 define?

• DM family - the cable family covered by this product standard for aircraft electrical use.
• AWG - American Wire Gage, used in the tables as the closest wire size reference.
• PTFE - polytetrafluoroethylene, the tape material used in the insulation build-up.
• UV - ultraviolet; in this standard it refers to UV laser printing on the cable insulation.
• DSC - differential scanning calorimeter, the test method named in Table 3.
• EN 3475-100 - the general aerospace cable test-method document whose terms, definitions and symbols apply here.
• EN 3838 - the standard for user-applied markings on aircraft electrical cables.

Who uses SIST EN 2267-008:2006?

SIST EN 2267-008:2006 is used by cable manufacturers, aerospace harness suppliers, aircraft electrical system designers, quality managers, test laboratories, and buyers. They use it to specify the cable build, confirm test coverage, qualify product, check markings, and compare offered sizes against the required cable code.

What changed in SIST EN 2267-008:2006 from the previous edition?

SIST EN 2267-008:2006 corresponds to EN 2267-008:2005.

Which standards are used with SIST EN 2267-008:2006?

• EN 2084 - gives the general technical specification used for packaging, labelling, delivery lengths and related product information.
• EN 2235 - covers screened and jacketed single and multicore electrical cables and is used here for cabling.
• EN 2267-002 - provides the general part for this cable series, including number of cores and colour coding.
• EN 3475-100 - supplies the general aerospace cable test methods, plus the terms, definitions and symbols used in this standard.
• EN 3838 - sets the requirements and tests for user-applied markings on aircraft electrical cables.
• EN 4434 - specifies the lightweight copper or copper alloy conductors used in the cable construction.
• EN 9133 - gives the quality management qualification procedure for aerospace standard parts.

What does the SIST EN 2267-008:2006 document contain?

The document contains a construction specification, a test matrix, and ordering and marking rules for DM family cables. Table 1 gives insulation layer details by size code, and Table 2 gives resistance, diameter and mass limits. Table 3 is the main technical core because it maps each EN 3475 test to this cable family and adds the temperatures, forces, durations and acceptance criteria to be used.

Clause 7 shows how the cable is designated, which helps with purchase descriptions and traceability. Clauses 8 to 10 link the product to marking, packaging, delivery lengths and technical specification requirements used in supply and inspection.
