is Single Burning Item 4 Requirements 4.1 General Product properties shall be assessed in accordance with Clause 5. To comply with this standard, products shall meet the requirements of 4.2, and the requirements of 4.3 as appropriate. NOTE 1 Information on additional properties is given in Annex C. One test result for a product property is the average of the measured values on the number of test specimens given in Table 5. NOTE 2 Apparent density is a useful parameter, among others, for the identification but it should not be used as a basis for the quality assessment of XPS products. Apparent density of XPS boards and billets, if voluntary declared by the manufacturer will be determined in accordance with EN 1602, Thermal insulating products for building applications – Determination of the apparent density. Apparent density of pipe sections, if voluntary declared by the manufacturer will be determined in accordance with EN 13470, Thermal insulating products for building equipment and industrial installations – Determination of the apparent density of preformed pipe insulation. Products manufactured from XPS can have the same thermal and mechanical properties at different densities. For this reason, product density is not quoted as requirement in this standard. 4.2 For all applications 4.2.1 Thermal conductivity For flat specimens, the thermal conductivity shall be based upon measurements carried out in accordance with EN 12667 or EN 12939 for thick products. For cylindrical specimens EN ISO 8497 shall be used as specified in 5.3.2.
In both cases, the thermal conductivity values shall be determined by the manufacturer and verified in accordance with EN ISO 13787, Subclause 5.3.1, and Annex B of this standard. They shall be declared by the manufacturer at reference mean temperatures covering the product service temperature range. The following conditions apply:  the measured values shall be expressed with three significant figures;  the declared conductivity curve shall be given as a limit curve, defined in EN ISO 13787;  the value of the declared thermal conductivity, λD, shall be rounded upwards to the nearest
0,001 W/(m·K); SIST EN 14307:2010

0,000 1 W/(m.K) for λ values below 0,1 W/(m.K) and in 0,001 W/(m.K) for λ
values above 0,1 W/(m.K). This shall be used as a reference for the verification of the declaration. When thermal conductivity is declared as a table derived from the equation, rounding upwards to the next 0,001 W/(m.K) has to be done for the full range of the thermal conductivity. NOTE Determinations of the declared thermal conductivity of pipe sections, following EN ISO 8497, having joints in metering area, include the effects of these joints as defined in EN ISO 23993.
4.2.2 Dimensions and tolerances 4.2.2.1 Linear dimensions of boards The length, l, and width, b, shall be determined in accordance with EN 822, the squareness,Sb , in accordance with EN 824, and flatness, Smax, in accordance with EN 825. No test result shall deviate from the declared values by more than the tolerances given in Table 1. Table 1 — Tolerances of length, width, squareness and flatness of boards Length or width mm Tolerances Length or width

4.2.2.2 Thickness of boards The thickness, d, shall be determined in accordance with EN 823. No test result shall deviate from the declared thickness, dD , by more than the tolerances given in Table 2 for the labelled class. SIST EN 14307:2010

4.2.2.3 Dimensions and tolerances of pipe sections and segments The length, l, thickness, d, inside diameter, Di, the deviation from the squareness, v, and the deviation from the linearity, L, of pipe sections and segments shall be tested in accordance with EN 13467. Products with a facing or natural skin shall be tested without removing them. No test result shall deviate from the declared values by more than the tolerances given in Table 3. Tolerances on prefabricated wares may be agreed between the parties. Table 3 — Tolerances for pipe sections and segments Length, l ± 10 mm Thickness, d a, ± 3 mm or ± 5% b Inside diameter, Di – 0 mm / + 4 mm or + 2 % b Squareness, v ± 6 mm or ± 2 % b Linearity, L ± 6 mm a
The tolerances only apply to unfaced products. The thickness of any facing exceeding 2 mm shall be indicated in the manufacturer’s literature. b
The greater value applies.
NOTE Smaller tolerances may be declared by a producer. 4.2.3 Dimensional stability Dimensional stability under specified temperature and humidity conditions shall be determined in accordance with EN 1604. The test shall be carried out after storage for 48 h at (23 ± 2) °C and (90 ± 5) % relative humidity. The relative changes in length, û0l, in width, û0b, and in thickness, û0d, shall not exceed 2 %. SIST EN 14307:2010

4.3.4 Compressive stress or compressive strength The compressive stress at 10 % deformation, σ10, or the compressive strength, σm, shall be determined in accordance with EN 826. No test result for either the compressive stress, σ10, or the compressive strength, σm, whichever is the greatest shall be less than the value given in Table 4, for the declared level. Table 4 — Levels for compressive stress or compressive strength Level Requirement kPa CS(10\Y) 100 ≥ 100 CS(10\Y) 150 ≥ 150 CS(10\Y) 200 ≥ 200 CS(10\Y) 250 ≥ 250 CS(10\Y) 300 ≥ 300 CS(10\Y) 400 ≥ 400 CS(10\Y) 500 ≥ 500 CS(10\Y) 600 ≥ 600 CS(10\Y) 700 ≥ 700 CS(10\Y) 800 ≥ 800 CS(10\Y) 1000 ≥ 1 000
4.3.5 Water vapour diffusion transmission properties Water vapour diffusion transmission properties shall be determined in accordance with EN 12086, and declared as the water vapour diffusion resistance factor, µ, for homogeneous products and as the water vapour resistance, Z, for faced or non-homogeneous products. No test result of µ shall be less than the declared level, MU, chosen from the following levels: 50; 80; 100; 150; 200; 250; 300. If Z is declared, no test result of Z shall be less than the declared value. Alternatively, for the declaration of water vapour transmission properties, the values quoted in EN ISO 10456 may be used. SIST EN 14307:2010

For pipe sections, segments and prefabricated wares fabricated from boards, the declared characteristics shall be determined on the boards from which they have been fabricated, except dimensions, squareness, flatness, pipe section linearity, thermal conductivity and reaction to fire.
EN 12939, provided it has been demonstrated that the results give safe (higher) values. The thermal conductivity shall be determined for the full temperature range of the product. For factory production control see Annex A. For XPS products for which ageing procedure applies, this procedure is described in Annex B. The results of ageing procedure performed on boards are also valid for pipe sections, segments and prefabricated wares fabricated from the same boards. For ITT, measurements of thermal conductivity made on two inside diameters of pipe sections at the greatest and smallest insulation thickness set of diameters are deemed to be representative of the total product range. For FPC, one dimension only is tested, i.e. one thickness of one diameter. NOTE Suitable sizes are e.g. 48 mm and 194 mm inside diameter. The guarded hot plate method EN 12667 or EN 12939 for thick products shall be deemed to be a suitable method for measurement of pipe sections having an inside diameter exceeding 500 mm. Flats products shall be prepared having the same thickness and density as the sections. If the guarded hot plate method is used the fact shall be stated in the test report. The thermal conductivity shall be determined directly at the measured thickness. If this is not possible it shall be determined by measurements on other thicknesses of the product providing that:  the product is of similar chemical and physical characteristics and is produced on the same production line/unit;  and it can be demonstrated that the thermal conductivity does not vary more than 2 % over the range of thicknesses where the calculation is applied. Where a product is manufactured in a range of thicknesses and the manufacturer chooses to characterise the entire range by declaring only one λ, he shall declare the highest λ of the range. If facings have been removed, this and the reason for the remove shall be stated in the test report. 5.3.3 Reaction to fire The tests shall be carried out in accordance with EN 13501-1. Rules for mounting and fixing are given in EN 15715:2009. Annex A of EN 15715:2009 gives tables for product and installation parameters for flat products and pipe insulation products as placed on the market. Installation parameters for standardized assemblies are only given for flat products. A conditioning period of six weeks applies before testing. SIST EN 14307:2010
