TY - RPRT A1 - Brosig, Laura A1 - Horn, Wolfgang A1 - Jann, Oliver T1 - Round Robin test for the implementation of odour measurements regarding ISO 16000-28 into the evaluation of buildings products - Part II (Specified by VDI 4302-1) N2 - While in 2012 a commercially available acrylic sealant was used as sample material, in 2014 a lacquer doped with specific substances was sent to the participants for the VOC and odour measurement. The resulting measurement values for the perceived intensity were evaluated in consideration of various boundary conditions to identify parameters that could possibly influence the measurement procedure significantly. For the comparison of both interlaboratory comparisons qualified data sets were taken as a basis. Potential for improvement identified in 2012 was mainly confirmed by the interlaboratory test 2014 as well. Besides the accurate conduction as essential part of the measurement it became obvious again that the boundary conditions of the DIN ISO 16000-28 are not defined tight enough. Moreover the thesis that measurements based on the utilisation of comparison scales with only one funnel generate results especially imprecise could not be verified. Both interlaboratory comparisons resulted in relative standard deviations of reproducibility that lay between 20 and 40 % and such are quite comparable with those of well-established interlaboratory VOC comparisons.

T1 - Two new promising approaches for quality assurance measures for materials emissions testing N2 - Two new approaches towards an emission reference material for use in quality assurance measures for materials emissions testing were developed and intensively tested. The overall goal was to obtain solid materials with homogenous and reproducible (S)VOC release. Since the application in inter-laboratory comparisons is aimed at, it should furthermore be long-term stable to ensure safe shipment to the customer without sustaining compound losses. In the first approach, thermoplastic polyurethane (TPU) was impregnated with the VOC texanol under high-pressure with liquid CO2 as solvent. In the second, styrene (VOC) and the SVOC 2,6-diisopropylnaphthalene (DIPN) were spiked into vacuum grease (VG) and a mixture of paraf-fin/squalane (P/S). For the prediction of the emission rates a finite element model (FEM) was developed for the VG and P/S type materials. All requirements for reference materials were fulfilled, whereas the TPU samples need to be aged for about 10 days until repeatable and re-producible emission rates were obtained.

A suited procedure for this purpose is the testing of one unique homogenous material in different laboratories within a Round Robin Test (RRT). Therefore, it is useful to have a reference material which can be used within inter-laboratory studies or as part of the quality management system to ensure comparable results. Several approaches on the development of reproducibly emitting materials have been published. These have in common only to emit a single VOC – toluene. Two further research studies carried out by BAM aimed to develop reference material for emissions testing containing one or more VOC in a single material. The first approach was a doped lacquer with Volatile and Semi-Volatile Organic Compounds (VOC/SVOC) and the second was Thermoplastic Polyurethane (TPU) or a Squalane/Paraffin mixture. Results received with the lacquer based material were presented in more detail.

Exhibit display cases should protect cultural objects from dust as well as from mechanical and physical damage. To ensure a stable climate inside the display cases, a low air exchange rate is maintained. Typically air exchange rates are often smaller than 0.1 d 1, which can result in rising concentrations of potential harmful immissions inside of the display cases due to emissions from materials. Especially high concentrations of organic acids, which can emit from e.g. sealing materials, can produce damage of cultural objects. In 2012 BAM introduced a procedure witch is called: BEMMA-Scheme (Bewertung von Emissionen aus Materialien für Museumsausstattungen) which stands for: “Assessment of Emissions from Materials for Museum Equipment”. Micro chambers are used for VOC emission tests of display case construction materials, e.g. textiles, plastics, sealing material, coatings and others. Each sampling procedure is carried out in duplicate. Emissions like formic acid, acetic acid, formaldehyde and oximes are excluded and the sum of emissions of VVOCs, VOCs and SVOCs is limited. For a positive assessment all listed criteria must be fulfilled; otherwise the display construction material fails the BEMMA scheme. The BEMMA scheme is not a guarantee for an emission free display case, but a necessary requirement for the choice of suitable materials for emission and immission reduced display cases. The basic evaluation for the values used for first assessments were a ZIM-project with nearly 100 tested materials. In-between more than 100 new materials were tested and enlarged the knowledge about material emissions from display case materials. Mainly silicone sealing materials were tested due to the fact that this group of material have the highest emissions. With regard to the testing procedure only construction materials were evaluated, not the display cases their self. Nevertheless in combination with the certificate also designed by BAM additionally the further steps of construction can be taken into account. So other factors such as age and storage time of materials, tightness respectively air change rate, air condition or ventilation of display cases can be included in the evaluation.

Labelling procedures for construction products are based on such emission test chamber measurements and hence measurement performance should be verified. A suited procedure for this purpose is the testing of one unique homogenous material in different laboratories within a Round Robin Test (RRT). Therefore, it is useful to have a reference material which can be used within inter-laboratory studies or as part of the quality management system to ensure comparable results. Any commercially available product on the market can be used as reference material, provided it is thoroughly characterised. However, these materials often emit only a few and material specific VOCs and appropriate homogeneity is not given. Therefore, alternative materials should be found. Several approaches on the development of reproducibly emitting materials have been published. These have in common only to emit a single VOC – toluene. Two further research studies carried out by BAM aimed to develop reference material for emissions testing containing one or more VOC in a single material. The first approach was a doped lacquer with Volatile and Semi-Volatile Organic Compounds (VOC/SVOC) and the second was Thermoplastic Polyurethane (TPU) or a Squalane/Paraffin mixture. Currently, the second approach is not at a level that it could be tested within a RRT. Important requirements for the production of a reference material were repeatability (homogeneity), reproducibility, long-term stability in terms of compound release and transport stability. The emission rates should be high enough to obtain well measurable chamber air concentrations at standardised test conditions. The lacquer samples were prepared by weighing portions of a water-based lacquer to which defined amounts of the pure analytes were added. Defined amounts of the lacquer mixture were filled into Petri dishes and cured under standard conditions (23 °C and 50% relative humidity). Reproducible emissions were obtained when the storage time of the cured material was not longer than four weeks. The concentrations were analyzed 7 days after loading of the material into the chamber. Two RRT were conducted by use of the lacquer system. Here, the laboratories had to identify and also to quantify the compounds. The relative standard deviations obtained were typical for such a kind of test. More than 50 participants reported results. N2 - Die Untersuchung von Produkten auf deren Emissionseigenschaften ist ein aktuell wachsender Aufgabenbereich für Messinstitute. Label werden für Bauprodukte auf Basis von Emissionskammermessungen vergeben, weshalb die dabei eingesetzten Messmethoden überprüft werden sollten. Ein Ringversuch (RV), bei dem ein homogenes Material von verschiedenen Laboratorien parallel untersucht wird, ist ein geeignetes Verfahren dafür. Für einen solchen Ringversuch aber auch generell für die laborinterne Qualitätssicherung ist es sehr hilfreich ein Referenzmaterial zu haben, um gut vergleichbare Ergebnisse zu erhalten. Generell kann jedes kommerziell erhältliche Produkt als Referenzmaterial verwendet werden, wenn es gut charakterisiert ist. Allerdings emittieren die meisten Produkte nur wenige VOC und diese sind typischerweise sehr materialspezifisch. Die Homogenität der Materialien ist nicht immer gegeben, so ist es besser, nach alternativen Materialien zu suchen. Es sind schon einige Veröffentlichungen zu reproduzierbar emittierenden Materialien verfügbar. Diese enthalten bislang zumeist nur ein einzelnes VOC – Toluol. Im Rahmen von zwei Forschungsvorhaben arbeitet die BAM an der Entwicklung von Referenzmaterialien für Emissionskammer-Untersuchungen, die einzelne VOC oder VOC-Mischungen emittieren. Der erste Ansatz war die Dotierung eines kommerziellen Lackes mit einer VOC/SVOC-Mischung, weitere Untersuchungen werden mit Thermo¬plastischem Polyurethan (TPU) sowie einer Squalan/Paraffin-Mischung durchgeführt. Da mit dem zweiten Ansatz noch Tests laufen, ist damit noch kein RV durchgeführt worden. Wichtige Anforderungen an ein Referenzmaterial sind die Wiederholbarkeit (Homogenität), Reprodu-zierbarkeit und Langzeitstabilität in Bezug auf die VOC-Abgabe und die Transportstabilität. Die Emissionsraten sollten hoch genug sein, um gut messbare Kammerluft-Konzentrationen bei Standardbedingungen zu erhalten. In einen wasserbasierten Lack wurde eine VOC/SVOC-Mischung zugegeben und nach der Durchmischung wurden davon einzelne Portionen in Petrischalen abgefüllt. Diese Schalen wurden unter Standardbedingungen (23 °C und 50% relative Luftfeuchtigkeit) getrocknet. Reproduzierbare Emissionen wurden erhalten, wenn die Lagerzeit ca. vier Wochen nicht überschritten wurde. Die Konzentrationen wurden sieben Tage nach der Beladung der Kammer bestimmt. Zwei RV wurden mit einem wie oben beschriebenen Lacksystem durchgeführt. Es nahmen ca. 50 Labore teil, diese mussten die Zielsubstanzen sowohl identifizieren als auch quantifizieren. Die gefundenen Mittelwerte und Standardabweichungen lagen jeweils im zu erwartenden Bereich für solch einen RV.

T1 - Reproducibly emitting reference material for quality assurance/quality control of emission test chamber measurements N2 - Volatile Organic Compounds (VOC) are ubiquitous in the indoor air, since they emit from materials used indoors. Investigations of these materials are mostly carried out in test chambers under controlled climatic conditions. Quality control of these test chamber measurements is important but there is a lack of commercially available homogenous reference materials as required for round robin tests or quality assurance of laboratories. The approach of the present study is the impregnation of a supporting material with VOC, which are reproducibly released in measurable chamber air concentrations under standardised test conditions. A polymer made of Thermoplastic Polyurethane (TPU) was chosen as carrier material. It was impregnated with the VOC trimethyl pentanediol isobutyrat (texanol).
