What is BS ISO 834-2 - Measuring furnace exposure about?
BS ISO 834 is an International Standard that discusses fire-resistance tests for elements of building construction.
BS ISO 834-2 is the second part in the multi-series that establishes general principles for measuring the uniformity of furnace exposure of samples tested in accordance with the requirements of ISO 834‑1. BS ISO 834-2 specifies the type and location of instrumentation used to measure the temperature, velocity, and oxygen content near the surface of simulated test samples. The surface of the simulated sample facing the furnace is a gypsum board secured to cold-formed steel supports.
Note: BS ISO 834-2 does not include requirements for furnace performance.
Who is BS ISO 834-2 - Measuring furnace exposure for?
BS ISO 834-2 on measuring furnace exposure is relevant to:
- Fire-test laboratories
- Manufacturers and suppliers of building materials and elements
- Construction industry
- Research and regulatory bodies
Why should you use BS ISO 834-2 - Measuring furnace exposure?
The purpose of BS ISO 834-2 is to describe a procedure to measure the exposure of a test sample to a furnace during a test conducted in accordance with ISO 834 (all parts).
The furnace exposure is determined by measuring temperature, air velocity and oxygen concentration at various locations. The procedure includes the use of low-cost, readily available, lightweight materials to represent the test sample. The recommended materials minimize the influence of variable moisture content among samples.
By complying with the requirements and recommendations given by BS ISO 834-2, you can measure and record fire exposure characteristics. The data obtained during this procedure is intended to provide a basis to demonstrate compliance with ISO/IEC 17025, for assuring the quality of test and calibration results.
