Product group classifications
Note:
This informative Annex has been written in mandatory language to facilitate adoption by anyone wishing to do so.
C.1 General
Manufacturers may be certified in up to four of the product group classifications, as specified in
Clauses C.2 to C.5.
C.2 Group A (architectural products)
Group A includes products that are decorative and establish the aesthetic character of a structure. These
products shall be produced in accordance with the requirements of this Standard. Group A is divided into
two categories:
(a) Architectural trim units (AT), which are non-prestressed products with a high standard of finish quality
and of relatively small size, can be installed with equipment of limited capacity. Products include sills,
lintels, coping, cornices, quoins, medallions, bollards, benches, planters, and pavers. This category
also includes specialty products specifically designed for a project but not commodity or ornamental
units produced for wholesale or retail purposes.
(b) Architectural cladding and load bearing units (A1) are precast concrete building elements (e.g.,
exterior cladding, load bearing and non-load bearing wall panels, spandrels, beams, mullions,
columns, column covers, and other miscellaneous shapes). Elements may be conventionally
reinforced and/or pretensioned or post-tensioned. This category includes category AT.
Note:
Group A does not include structural products that exhibit a high degree of finish or texture, including unique
colouration. Such products are included in Groups B and C.
C.3 Group B (bridge products) and Group BA (bridge
products with architectural finishes)
C.3.1 General
Both Group B and Group BA products shall be produced in accordance with the requirements of this
Standard.
C.3.2 Group B
Group B is divided into four categories:
(a) Precast concrete bridge products (B1) are conventionally reinforced precast concrete elements that
include some types of bridge beams or slabs, piling, sheet piling, pile caps, retaining wall elements,
median barriers, parapet walls, sound barriers and box culverts.
(b) Prestressed miscellaneous bridge products (B2) are any precast concrete and pretensioned or
post-tensioned elements, excluding superstructure beams. This category includes Category B1.
(c) Prestressed straight-strand bridge members (B3) include all precast concrete superstructure elements,
such as box beams, segmental components, I-girders, bulb tees, stemmed members, solid slabs, and
full- or partial-depth bridge deck slabs pretensioned or post-tensioned with straight strands. This
category includes Categories B1 and B2.
(d) Prestressed deflected-strand bridge members include the same class of products as category B3 and
which are pretensioned or post-tensioned with deflected strands. This category includes
Categories B1, B2, and B3.
