Glass in building — Forced-entry security glazing — Part 3: Test and classification by manual attack

ISO 16936-3:2005 sets forth a physical test method for security glazing designed to resist actions of manual attack by delaying access of objects and/or persons to a protected space for a short period of time. Its application is limited to the evaluation and the classification of the resistance of forced entry security glazing against the following threats: blunt tool impacts; sharp tool impacts; thermal stress; chemical stress (optional). It is not applicable to the use of power (motor- or engine-driven) tools or devices, explosives, military ordinance and tools, and processes or devices requiring more than two persons to transport and operate.

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 16936-3 was prepared by Technical Committee ISO/TC 160, Glass in building, Subcommittee SC 2, Use
considerations.
ISO 16936 consists of the following parts, under the general title Glass in building — Forced-entry security
glazing:
 Part 1: Test and classification by repetitive ball drop
 Part 2: Test and classification by repetitive impact of a hammer and axe at room temperature
 Part 3: Test and classification by manual attack
 Part 4: Test and classification by pendulum impact under thermally and fire stressed conditions

Introduction
ISO 16936 assesses security-glazing products that are more familiarly known as “anti-vandal”, “anti-bandit”,
and detention glazing products. Because there is no single test that will cover such a wide range of resistance
to attack, four separate test methods are provided to assess the forced-entry resistant properties of security
glazing. It is not intended that any particular test method be associated with the terms “anti-vandal” or “anti-
bandit”, since these terms can be only loosely defined and there is considerable overlap in their definition.
The test method specified in this part of ISO 16936 is a physical test using personnel and equipment and does
not reproduce the conditions of real human attack. The test relies heavily on the competence and experience
of personnel performing the test. The classification determined may not necessarily be reproducible and is
therefore considered as comparative of various glazing constructions.
The selection of tools to be used for the simulated attack is based on an attack which can be carried out
without regard to noise, smoke, vibration, etc. generated during the attack.

Glass in building — Forced-entry security glazing —
Part 3:
Test and classification by manual attack
1 Scope
This part of ISO 16936 sets forth a physical test method for security-glazing designed to resist actions of
manual attack by delaying access of objects and/or persons to a protected space for a short period of time. Its
application is limited to the evaluation and the classification of the resistance of forced-entry security glazing
against the following threats:
 blunt tool impacts;
 sharp tool impacts;
 thermal stress;
 chemical stress (optional).
It is not applicable to the use of power (motor- or engine-driven) tools or devices, explosives, military ordnance
and tools, and processes or devices requiring more than two persons to transport and operate.
NOTE Classifications have not been assigned to specific applications and glazing classification must be specified on
an individual basis for every application.

references, only the edition cited applies. For undated references, the latest edition of the referenced

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
action of force
deliberate action on the part of a person made with the intention of creating a hole in the security-glazing
product by the use of manually held implements or by the use of thrown objects
3.2
attack face
face of a test piece marked by the manufacturer and/or supplier that is designed to face the attack
3.3
category of resistance
classification of the capability of a security-glazing product to resist actions of force
3.4
protected space
space protected against access by the completed installation
3.5
sample
specified number of test pieces which together are representative of the security-glazing product intended to
comply with a particular category of resistance in this part of ISO 16936
3.6
security-glazing composition
specific construction of a glazing product
NOTE A product is deemed to be of the same or superior security-glazing composition if individual plies are
exchanged with others of a different colour, but without significant effect on the resistance to actions of force, and/or
additional glazing products are installed on either face of the security-glazing product, laminated to it or with an air space,
and/or additional equipment such as alarm wires, heating wires, printing, or surface coatings (on part or all of the surface)
are incorporated into the security-glazing product, provided that this does not significantly affect the resistance to actions
of force.
3.7
security-glazing product
product based on glass with or without plastics with a single or multiple ply construction, where the individual
plies are of uniform thickness over the whole area of the product
NOTE A security-glazing product is usually transparent or translucent, and provides a specific resistance to the
actions of force.
3.8
test piece
specified piece of security-glazing product submitted to a specified test procedure
3.9

4 Sampling
The sample submitted for testing shall consist of one test piece. To ensure against invalid test results because
of errors during the test, it is advisable to submit at least one extra test piece. Replicate testing is
recommended. Cut-outs and holes in security-glazing products should be avoided where possible, as these
can affect the resistance of the product.
The test piece shall be (1 100 ± 5) mm long × (900 ± 5) mm wide. The edges shall be free from visible chips,
cracks and flaws. Glass samples should be lightly arrissed for ease of handling.
The surface to be impacted shall be marked on each test piece.
Each test piece shall be conditioned vertically and be self-supporting at (18 ± 3) °C, for at least 12 h
immediately prior to the test.
5 Test piece support apparatus
Security-glazing products should be installed in a frame which can give appropriate resistance to impact and
which also provides a suitable support for the security-glazing product. See Figure 1.
The test piece support apparatus shall
 be inherently rigid,
 have an unyielding connection to a solid base and/or sturdy wall,
 ensure plane and parallel clamping of the test piece in a vertical position,
 be designed in such a way that the test piece touches only the clamping frame during the test,
 ensure clamping of the test piece on all four edges with an edge cover of (30 ± 5) mm,
 have the clamping frame, i.e. the fixed stop and adjustable stop, covered on the contact area of the test
piece with rubber strips 30 mm wide and 4 mm thick of hardness 40 IHRD to 60 IHRD according to
method N of ISO 48:1994,
2
 ensure that the edges of the test piece are clamped with a uniform pressure of (140 ± 20) kN/m ,
 allow mounting of the test piece in such a way that the bottom edge of the exposed faces (protected and
assaulted) of the test piece shall be no higher than 80 cm nor lower than 70 cm from the horizontal
surface supporting the operators.
