Introduction
Under the former Construction Products Directive, the concept of “conformity with the standard” has
make the assessment of fragmentation properties mandatory for thermally treated glass, as failing to
satisfy the fragmentation test (pass/fail criterion) forbid the manufacturer to claim compliance with the
relevant standard.
With the Construction Products Regulation, the concept of “conformity with the standard” doesn't exist
anymore. Therefore, in order to fulfil the needs of national regulations which presuppose that this
assessment is made, fragmentation properties have to be declared explicitly in the declaration of
performances (DoP).
The description of the fragmentation test was in the part 1 of six product standards, five of them using
the Method A and one using the method B (see bibliography, references [3] to [8]). But no reference was
made to this test in the harmonized part (part 2) of the same product standard. Moreover, glass
presenting specific shatter properties can be used as substrate or as component of further transformed
glass products, for which the possibility to declare the shatter property was not explicitly mentioned in
the respective hEN.
The aim by transferring the description of the fragmentation tests in a separate standard on shatter
properties is to allow for a declaration of this characteristic in the DoP. All hENs on glass products, when
revised, will make a reference to the shatter properties standard in their Clause 4, “Characteristics”.
Shatter properties will be a characteristic that will be possible to declare, like any other characteristic
already included in Clause 4.
The wording “shatter properties” is the one used in Mandate M/135. In order to be compliant with that
Mandate, the word “fragmentation” is replaced by “shatter properties” although nothing has been
modified in the description of the test methods.
1 Scope
This document gives test methods to assess the shatter properties of different types of monolithic flat
glass for use in building and construction works, for which a specific fragmentation pattern is required
when tested under defined conditions.
NOTE Thermally treated monolithic glass is a product for which such a requirement exists.
