SIST EN 4008-012:2009 is a SIST standard from the aerospace series for an electrical and optical connection accessory. It specifies the positioner used with the M22520/2-01 crimping tool to crimp the EN 3155-023 electrical contact according to EN 4008-002. In practice, it tells tool users, manufacturers and inspectors how this accessory is built, identified and used in the crimping process.

What does SIST EN 4008-012:2009 specify?

SIST EN 4008-012:2009 specifies the characteristics of a positioner for the M22520/2-01 crimping tool. The scope is limited to that accessory and its use with EN 3155-023 contacts, so the document is about the positioning and identification of the crimping aid, not the complete contact system.

The standard is organized into:

• Scope
• Normative references
• Terminology
• Required characteristics
• Designation
• Marking
• Technical specification

That structure matters because it shows where to look for the product description, the dimensional information, the material requirements and the linked technical rules.

What are the key requirements of SIST EN 4008-012:2009?

SIST EN 4008-012:2009 sets out how the positioner must function, what it must be made from, how it is identified, and where the broader technical specification comes from.

How the positioner works

Clause 4.1 describes the mechanical principle of the positioner. It is held on the crimping tool by two bayonets and the force of an internal spring acting on the central moving part, called the locator. The contact is positioned longitudinally by butting against a shoulder in the central bore.

In practice, this means the user does not set contact depth by guesswork. The design of the positioner controls the contact location before crimping, which helps repeatability.

What its size and mass are controlled by

Clause 4.2 gives the dimensions in Figure 1 and limits the mass to 30 g maximum. Figure 1 also identifies the data plate, manufacturer’s name and part number, bayonet lock pin and locator in the extended position.

For the reader, this means the standard combines geometry, identification and assembly layout in one place. If you manufacture or inspect the accessory, you use the figure as the reference for form and marking.

What materials are specified

Clause 4.3 specifies the body and ferrule materials. The positioner body is aluminium alloy with a blue colour, and the ferrule is stainless steel.

That matters because the document does not leave material choice open. The selected materials and finish are part of the product definition, so they need to be controlled in procurement and inspection.

How the product is designated

Clause 5 gives the designation format for the positioner, including the standard reference in the identity block. It also notes the possible use of code I9005 between the description block and the identity block.

In practice, this is the way to order, label or record the item consistently in technical documentation.

How it is marked

Clause 6 refers to Figure 1 for marking. The figure shows the key identification points on the positioner.

That means marking is part of the product definition, not an afterthought. It helps users match the accessory to the correct tool and part number.

Where the broader technical rules come from

Clause 7 points to EN 4008-001 for the technical specification. The product standard therefore sits within the EN 4008 series and relies on that companion document for the general technical framework.

What terms does SIST EN 4008-012:2009 define?

SIST EN 4008-012:2009 uses these terms in a specific crimping-tool context:

• Positioner - the accessory fitted to the crimping tool to locate the contact before crimping.
• Locator - the central moving part inside the positioner that helps set the contact position.
• Bayonet - the locking feature that secures the positioner on the tool.
• Indenters - the crimping parts of the tool that form the connection.
• Crimping tool - the hand tool used to make the crimped termination.
• Technical specification - the controlling technical document for the tool family, given here by EN 4008-001.

Who uses SIST EN 4008-012:2009?

SIST EN 4008-012:2009 is used in aerospace electrical connection work. It is relevant to manufacturers of crimping accessories, harness and connector assemblers, quality teams inspecting tooling, and buyers specifying the exact accessory for the M22520/2-01 tool.

It is also useful for maintenance and production staff who need a positioner that matches the correct contact and tool combination.

What changed in SIST EN 4008-012:2009 from the previous edition?

SIST EN 4008-012:2009 is identified as identical to EN 4008-012:2006.

Which standards are used with SIST EN 4008-012:2009?

The standard depends on these referenced documents:

• EN 2591-100 - provides the terminology used in the document.
• EN 3155-023 - defines the electrical contact that this positioner is intended to crimp.
• EN 4008-001 - gives the technical specification for crimping tools and associated accessories.
• EN 4008-002 - gives the list of product standards for the series.
• MIL DTL-22520/2-01 - identifies the hand crimping tool model M22520/2-01.

What does the SIST EN 4008-012:2009 document contain?

SIST EN 4008-012:2009 is a short product standard centered on one accessory and one application. It contains a figure of the locator assembly, a designation example, and the marking points shown on the product.

Its clauses give the scope, the referenced documents, the terminology basis, the required characteristics, the designation format, the marking reference and the link to EN 4008-001. For a reader, that means the document is mainly used to identify and control the correct positioner for aerospace crimping work.
