SIST EN 846-2:2001

SIST EN 846-2:2001 is a Slovenian standard that adopts EN 846-2:2000. It specifies a test method for determining the bond strength of prefabricated bed joint reinforcement in masonry specimens made from specified units and mortar. The method applies to designed prefabricated bed joint reinforcement complying with prEN 845-3 and is not intended for other reinforcement forms such as bars.

What does SIST EN 846-2:2001 specify?

SIST EN 846-2:2001 specifies one method for measuring how well prefabricated bed joint reinforcement bonds to mortar joints in masonry. The purpose is to test reinforcement in a realistic masonry specimen rather than as an isolated product, so the result reflects the interaction between the reinforcement, the mortar and the masonry units.

The standard is part 2 of the series on methods of test for ancillary components for masonry. In practice, that tells a buyer, specifier or test laboratory that this document is about one defined bond-strength test, not a general design code for masonry reinforcement.

The method applies to designed prefabricated bed joint reinforcement that complies with prEN 845-3. It does not apply to alternative reinforcement used in masonry, such as bars.

What are the key requirements of SIST EN 846-2:2001?

SIST EN 846-2:2001 centers on a controlled bond-strength test for prefabricated bed joint reinforcement in mortar joints. The important point for users is that the reinforcement is assessed in a masonry specimen made from specified units and mortar, so the test is tied to the actual masonry system.

Main points that matter in practice

• The test measures bond strength of prefabricated bed joint reinforcement.
  This matters because the result is used to judge how firmly the reinforcement interacts with the surrounding mortar joint.

• The specimen is a masonry specimen made from specified units and mortar.
  This means the test is not just about the reinforcement itself, but about its performance in a masonry assembly.

• The reinforcement must be designed prefabricated bed joint reinforcement.
  In practice, users need to make sure the product type matches the scope before using the method.

• The reinforcement has to comply with prEN 845-3.
  That links the test method to a defined product family, which is important when selecting samples for testing or comparing products.

• The method is for mortar joints.
  That means the relevant interface is the joint in which the reinforcement is placed, not another location in the wall.

• The method excludes other reinforcement forms, including bars.
  For users, this avoids applying the wrong test to products outside the intended scope.

• The standard is aimed at determining bond strength, not at prescribing the design of the masonry element.
  That distinction matters because the document is used for testing and assessment, not for structural design rules.

What terms does SIST EN 846-2:2001 define?

Bond strength - The measured ability of the prefabricated bed joint reinforcement to remain bonded within the mortar joint under the specified test method.

Prefabricated bed joint reinforcement - A reinforcement product made in advance and intended to be placed in bed joints of masonry.

Masonry specimen - The test piece built from specified units and mortar so the reinforcement can be assessed in a masonry arrangement.

Mortar joints - The joints in the masonry where the reinforcement is placed and where the bond performance is evaluated.

Designed prefabricated bed joint reinforcement - A prefabricated bed joint reinforcement product that falls within the scope intended by the standard and complies with prEN 845-3.

Who uses SIST EN 846-2:2001?

SIST EN 846-2:2001 is used by manufacturers of masonry ancillary components, testing laboratories, specifiers, quality managers and buyers who need to assess prefabricated bed joint reinforcement. It is relevant in masonry product testing, product qualification and quality control where bond performance in mortar joints must be checked against a defined method.

For a buyer or specifier, the standard helps confirm that a test result relates to the right product type. For a laboratory, it provides the test basis for preparing the masonry specimen and measuring bond strength consistently.

What changed in SIST EN 846-2:2001 from the previous edition?

SIST EN 846-2:2001 is identical to EN 846-2:2000.

Which standards are used with SIST EN 846-2:2001?

• prEN 845-3 - Identifies the designed prefabricated bed joint reinforcement to which this test method applies.

What does the SIST EN 846-2:2001 document contain?

SIST EN 846-2:2001 contains the European test method for bond strength of prefabricated bed joint reinforcement in mortar joints. The document frames the test around a masonry specimen built from specified units and mortar, which makes the result relevant to real masonry use rather than to a separate component alone.

For users, the practical value is in having a common test basis for comparing reinforcement products and checking whether a prefabricated bed joint reinforcement behaves as intended in masonry. The standard’s focus is narrow and technical: one bond-strength method, one product family, and one masonry context.
