SIST EN 2134:2004 is the Slovenian adoption of EN 2134:2001 from CEN for aerospace series round bars extruded in aluminium and aluminium alloys. It specifies dimensions and tolerances for bars with 10 mm < D < 220 mm, so manufacturers, buyers and inspectors can specify and check the same bar sizes for aerospace applications.
What does SIST EN 2134:2004 specify?
SIST EN 2134:2004 specifies the dimensions and tolerances of extruded round bars made from aluminium and aluminium alloys for aerospace applications. The document is organized into scope, normative references, the form of the bar, recommended dimensions and mass, and tolerances for diameter, length, straightness and roundness.
The standard is focused on product geometry and size control. It supports ordering, manufacturing and inspection by giving the dimensions to use and the tolerance limits to check against.
What are the key requirements of SIST EN 2134:2004?
SIST EN 2134:2004 sets out the product range first: it applies to round bars, extruded in aluminium and aluminium alloys, with diameters greater than 10 mm and less than 220 mm. In practice, this tells the reader which bar sizes are covered before any procurement or inspection work starts.
Dimensions and ordering information
Clause 4.1 gives recommended diameter and linear mass values. The table links nominal diameter to linear mass, with the mass values calculated using a density of 2.8 kg/dm3. For a buyer or planner, this is useful for estimating weight, stock and handling.
Clause 4.2 states that bars shall be supplied in fixed lengths or random lengths as specified on the order. For random lengths, the order shall state the minimum and maximum lengths. This matters because the supplier cannot choose the length basis on its own.
Diameter and length tolerances
Clause 5.1.1 gives diameter tolerances by diameter range. The tolerance increases as the nominal diameter increases, which means the allowable deviation is set according to bar size. Inspectors use this table to decide whether delivered bars are within limits.
Clause 5.1.2 gives length tolerances for bars supplied in fixed lengths. This is the control point for customers who need cut lengths rather than stock lengths, because the received length must match the ordered length within the stated limit.
Straightness and roundness
Clause 5.2.1 covers straightness. It refers the method of measurement and symbols to EN 3848, then gives straightness deviation limits by diameter range, including a limit per metre and a limit on any length. For practical use, this means straightness must be checked with the EN 3848 method and judged against the table.
Clause 5.2.2 covers roundness. It also refers the method of measurement to EN 3848 and gives roundness deviation limits by diameter range. This is the key control for how circular the bar section must be.
What terms does SIST EN 2134:2004 define?
Nominal D is the nominal diameter used to identify the bar size and to select the applicable tolerances.
Linear mass is the mass per unit length of the bar, given in kg/m, and it is used for weight calculations and planning.
Fixed lengths are bars supplied to a specified length, with a length tolerance applied to the ordered size.
Random lengths are bars supplied within a stated length range, with minimum and maximum values specified on the order.
Straightness deviation is the allowed departure from a straight bar shape, checked over one metre and over a specified length.
Roundness deviation is the allowed departure from a perfectly round cross-section.
Who uses SIST EN 2134:2004?
SIST EN 2134:2004 is used by aerospace material producers, distributors, purchasers and inspection personnel. Manufacturers use it to make bars to the right size, buyers use it to order the correct product form, and quality staff use it to verify diameter, length, straightness and roundness.
It is also relevant where aerospace material specifications need a common dimensional basis for incoming inspection and supply agreements.
What changed in SIST EN 2134:2004 from the previous edition?
SIST EN 2134:2004 is identical to EN 2134:2001.
Which standards are used with SIST EN 2134:2004?
EN 3848 provides the method of measuring form deviations, and SIST EN 2134:2004 uses it for straightness and roundness measurements.
EN 4258 gives the general organization of aerospace metallic material standards and explains how EN standards in this series relate to one another.
What does the SIST EN 2134:2004 document contain?
The document contains one form figure, one table for recommended diameter and linear mass, one table for diameter tolerances, one table for length tolerances, one table for straightness deviation and one table for roundness deviation. It also gives the ordering rule for fixed and random lengths and points to EN 3848 for the measurement methods used in geometric checks.
Taken together, these tables and references support product specification, purchasing and inspection of extruded aluminium and aluminium alloy round bars for aerospace use.
