1 Field of application
Lightweight horizontally perforated bricks are building materials for loadbearing and non-loadbearing brickwork. Lightweight horizontally perforated brick panels are not intended for loadbearing walls.
Lightweight horizontally perforated bricks and lightweight horizontally perforated brick panels are predominantly used for the construction of internal walls.
2 Concept
Lightweight horizontally perforated bricks and lightweight horizontally perforated brick panels are bricks which are moulded from clay, loam or clayey substances, with or without additives (air-entraining agents), and fired. Their apparent brick density shall not exceed 1,0 kg/dm3. The additives shall not have a long-term deleterious effect on the properties of the bricks.
3 Requirements
3.1 Shape
Lightweight horizontally perforated bricks and lightweight horizontally perforated brick panels shall have the shape of a unit defined by rectangles. Grooves or similar may be provided on the stretcher faces to improve plaster adhesion. Depressions may be made in the bed faces to accommodate reinforcements.
3.2 Types of brick
3.2.1 Lightweight horizontally perforated bricks are bricks in which the perforations run parallel to the bed face. They may be made with small perforations (cross section of an individual hole not exceeding 6 cm2) which accept mortar either entirely or in the marginal zone or with large perforations (cross section of an individual hole exceeding 6 cm2) (see table 1). The brick shall never be higher than it is wide.
3.2.2 Lightweight horizontally perforated brick panels are bricks in which the perforations run parallel to the bed face. The pattern of perforation is not specified. The height of the bricks shall exceed the thickness.
3.3 Perforations and webs
3.3.1 Perforations and webs shall conform to table 1. The webs shall be distributed over the cross-sectional area in such a way that the side walls and vertically running webs are stiffened by horizontally running webs or walls (see figures 1 and 3). They may be of any cross-sectional shape; rectangular perforations shall be preferred.

Lightweight horizontally perforated bricks and lightweight horizontally perforated brick panels shall be free from expansive particles, e.g. lime. If bricks contain expansive particles liable to diminish their usability, the test described in subclause 6.5 (water vapour test) shall be carried out.
Bricks shall be deemed to have passed the test if they exhibit no structural damage or if not more than 5 chips with a maximum depth of 3 mm occur for every 100 cm2 of external face.

3.9 Content of harmful salts causing efflorescence
Bricks shall be free from harmful salts leading to structural damage in the bricks or plaster. Bricks shall be deemed to have passed the test for harmful salts if the test described in subclause 6.5, carried out on loose bricks, shows that the proportion by mass of magnesium sulfate (MgSO4) does not exceed 0,12 %.

The following symbols shall be used for the various types of brick:
LLz lightweight horizontally perforated brick
LLp lightweight horizontally perforated brick panel
The sequence of elements used when designating lightweight horizontally perforated bricks shall be term, DIN number, type of brick (symbol), compressive strength class, apparent brick density class and format symbol as given in table 6.
Example of designation:
Designation of a lightweight horizontally perforated brick (LLz) of compressive strength class 12, apparent brick density class 0,9, length l = 240 mm, width b = 175 mm and height h = 113 mm (3 DF):
Brick DIN 105 — LLz 12 — 0,9 — 3 DF
The sequence of elements used when designating lightweight horizontally perforated brick panels shall be DIN number, type of brick (symbol), apparent brick density class and format symbol as given in table 7.
Example of designation:
Designation of a lightweight horizontally perforated brick panel (LLp) of apparent brick density class 0,6, length l = 330 mm, height h = 238 mm and thickness s = 80 mm (80 s):
Brick DIN 105 — LLp 0,6 — 80 s
If lightweight horizontally perforated brick panels are produced with differing length or height, these dimensions shall also be stated in the designation.
Example of designation:
Designation of a lightweight horizontally perforated brick panel (LLp) of apparent brick density class 0,6, length l = 495 mm, height h = 320 mm and thickness s = 60 mm:
Brick DIN 105 — LLp 0,6 — 495 × 320 × 60
5 Marking
All bricks shall be provided with a works mark (manufacturer's mark) and the symbol identifying the brick type (LLz or LLp).
Lightweight horizontally perforated bricks ready for dispatch shall additionally be marked on one stretcher face with a colour coding stripe not less than 20 mm in width, indicating the compressive strength class (see table 8) and details of their apparent brick density class.
An indication of the apparent density class is considered adequate for lightweight horizontally perforated brick panels.
It shall be deemed sufficient if one brick is marked for up to 200 lightweight horizontally perforated bricks not less than 10 DF and for up to 50 lightweight horizontally perforated brick panels.

6 Testing
If bricks are packaged, it shall be deemed sufficient if the packaging or an attached label gives the works mark, brick type, apparent brick density class and compressive strength class (for lightweight horizontally perforated bricks).
6.1 Shape, dimensions, perforation
In accordance with DIN 105 Part 1.
A measuring rule or a gauge board with a millimetre scale is sufficient for measuring the length of lightweight horizontally perforated brick panels with dimensions exceeding 495 mm.
The deflection shall also be determined for lightweight horizontally perforated brick panels as illustrated in figure 5. In this determination, the panel shall be pressed on a longitudinal face or width against a smooth surface. Deviations from straightness shall be determined using a measuring wedge and stated to the nearest whole millimetre.
6.2 Apparent brick density
In accordance with DIN 105 Part 1.
6.3 Compressive strength
In accordance with DIN 105 Part 1.
Lightweight horizontally perforated bricks, including standard format bricks, shall be tested as whole bricks. Form factors shall not be applied.
6.4 Bending strength
The bending strength of lightweight horizontally perforated brick panels shall be determined on 5 air-dried samples.
Each panel shall be tested lying flat. The panel shall be placed on two supports so that it can move and stressed in the middle parallel to the supports by means of a 20 mm wide mandrel. The distance between supports shall equal the length of the panel minus 50 mm. The load shall be increased steadily at a rate of approximately 10 N per second.
6.5 Expansive particles and water-soluble salts
In accordance with DIN 105 Part 1.
7 Inspection
7.1 General
See DIN 105 Part 1.
7.2 Internal control
In accordance with DIN 105 Part 1.
7.3 Third party inspection
In accordance with DIN 105 Part 1.
The inspection of lightweight horizontally perforated brick panels shall include the bending strength test instead of the compressive strength test and the determination of deflection.
