BS ISO 10295-2:2009
Fire tests for building elements and components. Fire testing of service installations. Linear joint (gap) seals

This part of BS ISO 10295 specifies the heating conditions, methods of test and criteria for the evaluation of the ability of a linear joint seal to maintain the fire integrity and thermal insulation of a fire-separating element at the joint being sealed.

The purpose of the tests is to assess the integrity and insulation performance of the linear joint seals, including the effects of induced movement in those cases where the joint is designed to accommodate movement and has a width greater than 20 mm.

It is not the intention of this part of BS ISO 10295 to provide quantitative information on the rate of leakage of smoke and/or gases, or on the transmission or generation of fumes, although such phenomena can be recorded in describing the general behaviour of specimens during the test.

It is not the intention of this standard to evaluate joint seals where special test procedures already exist, e.g. doors, partitions, penetrations, pipes, ducts and cables.

BS ISO 10295 consists of the following parts, under the general title Fire tests for building elements and components — Fire testing of service installations:

  • Part 1: Penetration seals
  • Part 2: Linear joint (gap) seals

A Part 3 dealing with guidance on the use of a test configuration to establish the direct and extended fields of application for single-component penetration seals is under development.

This part of BS ISO 10295 describes test methods used to determine the fire resistive nature of joint seals when subjected to the standard fire-exposure conditions outlined in BS ISO 834-1.

Joint seals are positioned in joints, voids, gaps or other discontinuities between or bounded by two or more supporting elements. Normally such openings are denoted as “linear” because the length is greater than the width, defined by a typical ratio of at least 10:1 as in practice.

Joints are present in buildings as a result of:

  • Design to accommodate various movements induced by thermal differentials, seismic events and wind loads and exist as a clearance separation
  • Acceptable dimensional tolerances between two or more building elements, e.g. between non-load-bearing walls and floors
  • Inadequate design, inaccurate assembly, repairs or damage to the building.

This part of BS ISO 10295 describes methods of test for evaluating joint seals based on their intended use. It also allows for the application of movement prior to and/or during fire testing.

This standard provides the requirements for the test specimen, the test construction, the equipment (including any special apparatus or instrumentation), the procedures and acceptance criteria as they apply to joint seals and their supporting elements.
