This document describes two methods for determining the content of polycyclic aromatic hydrocarbons (PAH) and one method for determining the content of benzene, toluene, ethylbenzene and xylenes (BTEX) with gas chromatography with mass spectrometric detection (GC-MS).

See Annex A for a list of PAH and BTEX that can be determined with this document.

This document is intended to be used for construction products.

In a number of cases additional analysis with high performance liquid chromatography (HPLC) can be necessary to determine a number of compounds. To determine PAH multiple liquid-liquid extraction is used to remove disturbing compounds. The tests that led to this document were carried out on different types of roofing material, asphalt and one tar containing asphalt, [3] and [5].

The detectability limit of the methods for individual compounds in roofing material, asphalt and tar containing asphalt for PAH is 0,5 mg/kg to 1,5 mg/kg and for BTEX 0,1 mg/kg.

The working range depends on the matrix and the interferences encountered.

NOTE 2       The limit of detection of most elements will be affected by their natural abundance, ionization behaviour, on abundance of isotope(s) free from isobaric interferences and by contamination (e.g. handling and airborne). Handling contaminations are in many cases more important than airborne ones.

The limit of detection will be higher in cases where the determination is likely to be interfered (see Clause 6) or in case of memory effects (see e.g. EN ISO 17294‑1:2006).

The method in this document is applicable to construction products and validated for the product types listed in Annex A.

This document covers factory-made reflective insulation (RI) products intended for use as thermal and acoustic insulation of buildings. The products are manufactured in the form of rolls or boards. They are made from low emissive film(s) and infrared semi-transparent material layer(s) or air cavities.

This document describes the methods and criteria for assessing the performance of factory-made reflective insulation products in relation to essential product characteristics and includes the procedures for assessment and verification of the constancy of performance.

Reflective insulation products require specific setup instruction(s) depending on their level of compressibility.

This document does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards.

This document does not cover:

—    products intended to be used for the insulation of building equipment and industrial installations;

—    products made of mineral wool, polystyrene or polyurethane foams (not inclusive) faced with aluminium or metalized foil on one or both external surfaces (which are already covered by a corresponding harmonized European product standard);

—    membranes used as vapour control layer (VCL) or vapour-permeable roof or wall underlay (which are already covered by a specific harmonized European product standard).

This document specifies requirements and test methods for room temperature sensors used to control the room temperature.

This document covers wall mounted and flush mounted room temperature sensors.

The following aspects are not covered by this document:

—    Pendulum temperature sensors

—    Ceiling mounted temperature sensor

—    Extract air temperature sensors

NOTE          The measured value available at the output of the sensor is influenced by the place where the sensor device is located and factors such as air velocity, wall temperature, self/waste heating of the device and the air temperature. The perceived temperature, which is important for the well-being of a person, depends among other factors on air temperature, temperature of the surrounding walls and air flow rate as indicated in EN ISO 7730.

The temperature sensor element can be combined with other sensors in one device. This document only deals with the room temperature sensing of this devices. Other sensors are not covered except of their influence on the room temperature sensing (e.g. self-heating).

This document specifies sensor characteristics contributing to the determination of the control accuracy of individual zone controller according to EN 15500‑1.
