Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies) The work of preparing International Standards is normally carried out through ISO technicalcommittees Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3

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 part of ISO 9652 may be the subject of patentrights ISO shall not be held responsible for identifying any or all such patent rights

International Standard ISO 9652-5 was prepared by Technical Committee ISO/TC 179, Masonry, Subcommittee

SC 3,Test methods

ISO 9652 consists of the following parts, under the general titleMasonry:

Vocabulary

1 Scope

This part of ISO 9652 defines terms used in the structural design of unreinforced masonry

This part of ISO 9652 is applicable to masonry in general, except for the following aspects of masonry design:a) seismic design;

b) resistance to fire (see ISO/IEC Guide 52);

c) thermal insulation (see ISO 7345);

of applying the most recent edition of the normative document indicated below For an undated reference, the latestedition of the normative document referred to applies Members of ISO and IEC maintain registers of currently validInternational Standards

3.2 Unit types according to material

3.2.1

calcium silicate unit

unit formed from a mixture of lime and predominantly siliceous materials, shaped by pressing and combined by theaction of steam under pressure

3.2.2

clay unit

unit formed predominantly from clay, loam, brickearth or shale, subsequently fired to a temperature sufficiently high

to produce an adequate ceramic bond

3.2.3 Concrete units

3.2.3.1

autoclaved aerated concrete unit

unit formed from a mixture of fine siliceous aggregate, hydraulic binder, other materials and an aeration agent, thenautoclaved after rising and cutting

3.2.3.2

dense-aggregate concrete unit

unit formed from a mixture of normal-density aggregate, hydraulic binder and other materials, moulded underpressure and/or vibration

3.2.3.3

lightweight-aggregate concrete unit

unit formed from a mixture of low-density inorganic principal aggregate, hydraulic binder and other materials,moulded under pressure and or vibration

3.2.4 Stone units

3.2.4.1

dressed stone unit

unit formed from natural stone by cutting or cleaving to a regular rectangular shape

3.2.4.2

manufactured stone unit

unit formed from aggregate and cementitious binder; intended to resemble, and to be used for similar purposes tothat of, natural stone

3.3 Grouping of units according to their percentage and direction of holes as laid in the wall

Trang 7

nominal size (deprecated)

size of a coordinating space allocated to a unit including allowances for joints and tolerances

3.5.2

work size

size of a unit specified for its manufacture to which the actual size should conform within specified permissibledeviations

Trang 8

Trang 9

Figure 3 — Shell and web

Trang 10

Trang 11

component to attach two assemblies to one another

EXAMPLE A floor or a roof can be connected to a wall

NOTE The term connector includes anchors, straps and ties (5.5.4).

Trang 12

metal connector, one end of which is firmly supported by a wall or other structural member and into which the end

of a joist (timber beam) sits

Trang 13

characteristic dead load

dead load based on specified dimensions and densities

characteristic imposed or wind load

load which has a probability of not more than 5 % of being exceeded where it acts unfavourably or, where it actsfavourably, the load which has a probability of at least 95 % of being exceeded

6.6.1

axial loading

application of a load to a member along an axis

Trang 14

Trang 15

6.10.4

shear strength

strength of masonry subjected to equal and opposite parallel forces that tend to displace, or produce relative sliding

of, adjacent planes

6.10.5

tensile strength

strength of masonry subjected to direct tensile forces

6.11 Strength of masonry units

site compressive strength

compressive strength of mortar specimens made from samples of fresh mortar taken from the site

6.13

support

means of carrying vertical load

SEE also restraint (6.8)

Trang 16

Trang 17

7.8.3

double-leaf wall

collar-jointed wall (deprecated)

two parallel leaves with the space between (not exceeding 25 mm) filled solidly with mortar and tied together so as

to result in common action under load

7.8.4

faced wall

wall in which the facing and backing are bonded so as to result in common action under load

7.8.5

grouted cavity wall

two paralled single-leaf walls, spaced at least 50 mm apart, securely tied together with wall ties and with theintervening cavity filled with grout so as to result in common action under load

pocket-type retaining wall

reinforced masonry wall with the main reinforcement in concrete-filled vertical pockets formed in the tension face ofthe masonry

indentation in a face of the wall

9 Test methods and equipment

9.1

air-dried condition

moisture content achieved by prolonged exposure to ambient conditions in a laboratory

Trang 18

9.2

capping

material applied to the surfaces of a specimen to make them plane and parallel

EXAMPLE Mortar or gypsum

mean area of the cross-section of solid material of a unit or the gross area less the area of voids and re-entrants

10.2 Density of masonry units

powders and wet mortarmass per unit volume

10.3 Volume of masonry units

Trang 19

initial rate of absorption US

average rate, measured over 1 min, starting from the first contact, at which the bed face of the masonry unitabsorbs water at ambient temperature

NOTE The suction rate is expressed as a mass per unit area of the gross area of the bed face per unit time However, theinitial rate of absorption is based upon the net area of the bed face

ability of mortar to retain its moisture under suction from a masonry unit
