Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 10135 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product

specifications and verification.

This second edition cancels and replaces the first edition (ISO 10135:1994), which has been technically

revised.

ISO 10135:2007(E)
Introduction

This International Standard is a technical product documentation (TPD) standard (as prepared by ISO/TC 10),

but also serves as a geometrical product specification (GPS) standard (as prepared by ISO/TC 213) and is to

be regarded as a complementary process specific tolerance GPS standard (see ISO/TR 14638). It influences

links 1 and 2 of the chain of standards on mouldings.

For more detailed information of the relation of this International Standard to other standards and the GPS

matrix model, see Annex B.

Materials that are moulded to produce parts may exist in a solid, doughy or liquid form.

In order to produce parts by moulding, it is recognized that special consideration has to be made concerning

the moulding process and the designs of the mould, which influence the design of the part.

It is often necessary to slightly change the intended geometry of a part in order to avoid surface imperfections

(e.g. caused by sinks due to thermal contraction of material) and in order to enable the removal of the part

from the mould. Different necessary mould components such as parting surfaces, gates, risers, vents, ejectors

etc. can also produce undesired, but inevitable surface imperfections. Therefore, the resulting moulded part

will exhibit deviations from the ideal geometric form. To control these deviations in order to achieve the

intended function and to ensure that the moulded part can be reproduced when a mould shall be replaced

(e.g. due to breakdown), it is necessary that such permissible deviations be able to be indicated and specified

on technical drawings.

Moulded parts, cast parts and forged parts are parts produced by the use of a mould, e.g. by blowing, injection,

casting or forging. For convenience, the use of the term “moulded part” in the text of this International

Standard covers moulded or cast or forged parts.

The tolerance specified for a casting may determine the casting method. It is therefore recommended, before

the design or the order is finalized, that the customer liaise with the foundry to discuss:

a) the proposed casting design and accuracy required;
b) machining requirements;
c) method of casting;
d) the number of castings to be manufactured;
e) the casting equipment involved;
f) datum target system according to ISO 5459;
g) casting alloy;

h) any special requirements, for instance, individual dimensional and geometrical tolerances, fillet radii

tolerances and individual machining allowances.

Although the figures in this International Standard are presented in first angle projection, they could equally

well have been presented using third angle projection.

6.2 Tool markings

When it is necessary to specify the size of the maximum permissible deflection caused by auxiliary mould

components i.e. gates, risers, vents, ejectors and other types of tool markings, they shall be indicated by the

graphical symbol shown in Figure 7. This shall be placed above a reference line (see ISO 128-22) connected

to the feature by a leader line and an arrowhead, which is pointing to the surface as shown in Figure 8. The

type of marking is indicated with a letter symbol according to Table 4 after the graphical symbol. If the type of

markings is another than any of those listed in Table 4 the type shall be stated in full text/writing instead of a

letter symbol. For details of the symbol, see Figure A.3.

A plus and/or minus sign shall be indicated after the letter symbol or the text indicating the type of tool marking,

see Figure 9. A plus sign is used if the tool marking shall be elevated above the adjacent surface of the

moulded part as shown in Figure 9 a). A minus sign is used if the tool marking shall be depressed below the

adjacent surface of the moulded part as shown in Figure 9 b). The plus and minus sign is used when elevation

The maximum permissible local deviation of the tool mark from the surface may be indicated by adding values

after the plus and/or minus sign, see Figure 10. The value representing the maximum permissible rise above,

and/or depression below, the surface shall always be stated.
Figure 10 — Example of tool marking symbol

If it is necessary to specify the maximum permissible area, this area shall be indicated in brackets after the

value of the maximum permissible rise above, and/or depression below the surface, i.e.:

⎯ as a diameter on the surface of the moulded part [Figure 11 a)] by one value or

⎯ by two values representing the dimensions of a rectangle on the surface of the moulded part

[Figure 11 b)] where the first value represents the direction in the plane of the drawing and the second

value represents the direction orthogonal to the plane of the drawing.
a) As a diameter b) As a rectangle

Figure 11 — Example of tool marking symbols used with specification of maximum permissible area

and deflection area

Values for maximum permissible flash can be specified on the right hand side of the graphical symbol for tool

marking below the reference line, see 6.5 and Figure 12.

Figure 12 — Example of indication of permissible limit of flash at an ejector marking

The location of tool markings on the surface of a moulded part shall be indicated and toleranced in

accordance with ISO 1101.
6.3 Special ejector markings identifier

If necessary for recognition purposes, the ejector markings shall be specifically indicated on the drawing. The

graphical symbol shown in Figure 13 shall be used. For details of the symbol, see Figure A.4.

symbol for specifying maximum permissible elevation and or depression as shown in Figure 14.

marking symbol
6.4 Mismatch
6.4.1 General

Surface mismatch may appear on real features and is formed by more than one mould component at the

location where the parting surface intersects the features. Surface mismatch may be generated e.g. by a main

parting surface, a slider, a tooling insert or a parting surface between two mating cores etc.

Examples of surface mismatch caused by dimensional, linear and rotational mismatch are given in Figures 15,

16 and 17 respectively.

components

Rotational mismatch.

Since mismatch is an undesirable product of a moulding process, it may be necessary to control its

appearance by specifying the maximum permissible surface mismatch.
