D.T.D. 5102
(Superseding in part Specification D.T.D. 330)
October, 1959
Reprinted October, 1964

Ministry of Defence
MINISTRY OF AVIATION
Aircraft Material Specification
SOFT IRON FOR DYNAMO-ELECTRIC MACHINES
(Type B)

NOTE 1. This specification is one of a series issued by the Ministry of Aviation, either to meet a limited requirement not
covered by any existing British Standard for aircraft material or to serve as a basis for inspection of
materials the properties and uses of which are not sufficiently developed to warrant submission to the British
Standards Institution for standardisation.

NOTE 2. The material is intended primarily for magnetic relays, the yokes of dynamo-electric machines and for
other stationary parts of magnetic circuits carrying a direct flux. It is purified iron with high permeability at
flux densities between 15,000 and 19,000 gauss (1.5 and 1.9 webers/m2).

NOTE 3. This specification together with specification D.T.D. 5092 supersedes specification D.T.D. 330.
D.T.D. 5102 differs front D.T.D. 5092 only in the requirement for magnetic characteristics.

Sheet, strip, and plate
Bars and billets for forging
Forgings
Bars for machining
Tubes

Chemical composition
1.1. The material shall consist of iron of a purity sufficient to give the magnetic characteristics required
by Clause 8.
Definitions
2.1. Cast. The term “cast” shall be taken to mean the material derived from any one original furnace
charge.
2.2. Batch. A “batch” shall consist of one cast or, at the discretion of the Inspecting Authority, an
aggregate of casts up to a total of 10 tons from any one “furnace run” on the same material.
Condition
3.1. The material shall be supplied either in the “as manufactured” or heat-treated condition as stated
on the order.
NOTE. Material supplied in the “as manufactured“ condition will require heat treatment in
accordance with Clause 4 in order to achieve the magnetic properties specified in Clause 8.
Heat-treated material, after machining, may require further heat treatment under nonscaling conditions as given in
Clause 4.3 in order to restore the original magnetic properties.
Heat treatment
4.1. Material to be supplied in the heat-treated condition shall be heat treated together with its representative test pieces.
4.2. Except as provided in Clause 4.4 test pieces and material to be supplied in the heat-treated condition shall be heated
at a temperature between 920°C and 940°C for not less than one hour,
cooled at a rate not exceeding 50°C per hour to a temperature of 670°C or less, and cooled thereafter at the natural rate of
cooling of the furnace.
4.3. In order to prevent the formation of scale, test pieces shall be heated either in suitable closed
containers, or in a furnace atmosphere of hydrogen (preferably) or cracked ammonia containing not
more than 0.5 per cent of residual ammonia. Contamination by sulphur, oxygen or carbon is to be
avoided, and cast-iron containers shall not be used.
4.4. With the concurrence of the Inspecting Authority, an alternative heat treatment that will ensure
compliance with the requirements of Clause 8 may be used.
5 Freedom from defects
5.1. The material shall be free from harmful defects.
5.2. Any material may be rejected for faults in manufacture although it may have passed the magnetic
test specified in Clause 8 below.
Margins of manufacture
6.1. The tolerances on the thickness of sheets, strips and plates, the diameters of bars and the dimensions
of forgings shall be agreed between manufacturer and purchaser and stated on the order.
6.2. The tolerances on the dimensions of tubes shall be as follows:
Outside diameter
Up to and including 2″ … … …
Over 2″, up to and including 3¾” …
Over 3¾” … … … …
Thickness
For all sizes … … … …
Selection and preparatiou of samples for magnetic tests
7.1. The Inspector shall select an ingot from each batch from which three sections. including one from
or
7.2.
7.3.
each end shall be cut to provide three test samples. One sample shall either
(a) (preferably) be pierced. forged without welding, and machined to a ring with the following
dimensions:
Outside diameter of ring … … … 4 inches
Radial thickness … … … … ¼ inch
Axial length … … … … ½ inch
(b) be forged to a bar for testing in a compensated yoke permeameter, in accordance with the provisions of B.S.2454.
Alternatively. where the material is supplied in the form of tubes, a sample shall be cut from the
batch and shall be machined to a radial thickness of not more than of the mean diameter, and to an
axial length which shall ensure a radial cross sectional area of from 1 to 10 sq cm (0.16 to 1.6 sq in).
Test pieces shall be heat-treated in accordance with Clause 4.2 and shall not be mechanically worked
before testing in accordance with Clause 8.
Magnetic tests
“8.1. After the heat treatment specified in Clause 4, test pieces shall be submitted to magnetic tests in accordance with one of the
methods specified in B.S.2454, recording either B against H or vice versa. The results
obtained shall comply with the requirements of Table 1 or Table 2 below. The tests shall be carried out by
the manufacturer, unless the order states that they will be carried out by the purchaser after delivery.”

Coercive force. After a test piece has been subjected to a magnetising force sufficient to produce in it
a flux density of 15,000 gauss (1.5 weber/m2
) the coercive force shall be not more than 1.5 oersted
(120 amp/m). The measurement of coercive force may be made by any suitable means, using the
same specimen as for the B/H measurement.

Ingots. If any test piece fails to comply with the requirements of Clause 8 the remaining two samples
of the set of three shall be prepared as described in Clauses 7.1 (a) or (b), and 7.3. Both test pieces
shall comply with the requirements of Clause 8.
Tubes. If any test piece fails to comply with the requirements of Clause 8, the Inspector shall select
for test from the batch two further samples, one of which shall be from the tube from which the
original test sample was taken, unless that tube has been withdrawn by the manufacturer. The
test pieces prepared from both these further samples in accordance with Clause 7.2 and 7.3 shall
comply with the requirements of Clause 8.
