The work of preparing International Standards is normally carried out through
9、 ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborate
10、s closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards
11、. 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. In exceptional circumstances, when a technical committee has collected
12、data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to
13、 be reviewed until the data it provides are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

17、 is to recommend 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 recommended procedure includ
18、es 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.

19、construction Part 2: Guidance on measuring uniformity of furnace exposure on test samples 1 Scope This Technical Report establishes general principles for measuring the uniformity of furnace exposure of samples tested in accordance with the requirements of ISO 834-1. This Technical Report specifies
20、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 gypsum board secured to cold-formed steel supports. This Technical Report does not include requi

23、nstrumentation 4 Test equipment 4.1 Supporting construction 4.1.1 The supporting construction shall consist of cold-formed steel supports faced with two layers of gypsum board a minimum of 16 mm thick intended for use in fire-barrier assemblies on the side facing the furnace and with a single-layer
24、structural panel a minimum of 18 mm thick on the side facing away from the furnace. NOTE 1 Gypsum boards used in fire barrier assemblies are identified as Type X by ASTM C1396 and as Type F by EN 520. NOTE 2 Plywood and oriented strand boards are considered typical structural panels. ISO/TR 834-2:20
