  • Molds

  • ...and some more

  • Certification of emission of building products

    voluntary,

    controlled production,

    assesment of builiding

    products:

    basics of materials,

    emissions,

    different testing schemes

    different criteria

  • ANNEX I

    Council Directive 89/106/EEC of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products

    3. Hygiene, health and the environment

    The construction work must be designed and built in such a way that it will not be a

    threat to the hygiene or health of the occupants or neighbours, in particular as a

    result of any of the following:

    - the giving-off of toxic gas,

    - the presence of dangerous particles or gases in the air,

    - the emission of dangerous radiation,

    - pollution or poisoning of the water or soil,

    - faulty elimination of waste water, smoke, solid or liquid wastes,

    - the Presence of damp in parts of the works or on surfaces within the works

  • Sampling strategies for indoor air (ISO 16000-5)

    Aims of sampling:

    finding the causes of health problems

    determination of long term exposure,

    identification of emission sources,

    assessment of remediation.

    Parameters to consider:

    sampling time,

    sampling place,

    sampling duration,

    choice of sorbents.

  • Classification of air pollutants

    Name Abbreviations Boiling point range (C)

    Very Volatile Organic Compounds VVOC 380

  • Dcret no 2012-14 du 5 janvier 2012 relatif lvaluation des moyens daration et la mesure des polluants effectues au titre de la surveillance de la qualit de lair intrieur de certains tablissements recevant du public

    French regulation

    passive sampling for benzene and formaldehyde

    TD-GC/MS analysis for benzene,

    HPLC for formaldeyhde

  • Method Target compounds Standard Sampling time

    QL

    Volatile organic compounds with TD/GC-MS (active sampling) (C6-C16)

    Hydrocarbons, terpenes, alcohols, ethers, ketones, aldehydes, glycols, glycol-ethers, carboxylic acids, halogenated hydrocarbons

    ISO 16000-6 1 hour 5 ng/sample

    Volatile organic compounds with TD/GC-MS (passive sampling) (C6-C16)

  • Quality assurance for TD-GC/MS analysis:

    participation in round robin tests (interlaboratory comparison)

    proper conditioning of tubes,

    logbook for each tube,

    blanks:

    laboratory blank,

    field blank,

    trip blank.

  • Thank you for your attention!
