200  DEFINITIONS

     201  ABS WELDING ADHESIVE:  Any adhesive that is intended by
          the manufacturer to weld acrylnitrile styrene (ABS)
          plastic pipe.

     202  ADHESIVE:  Any substance that is used to bond one surface
          to another surface by attachment.

     203  ADHESIVE PRIMER:  Any coating that does not contain any
          adhesive and is intended by the manufacturer to be
          applied to a substrate, prior to the application of an
          adhesive, to provide a bonding surface.

     204  AEROSOL ADHESIVE:  A mixture of rubber, resins, and
          liquid and gaseous solvents and propellants packaged in
          a disposable pressurized spray container for hand-held
          application.

     205  AUTOMOTIVE GLASS PRIMER:  Any adhesive primer that is
          intended by the manufacturer to be applied to automotive
          glass prior to installation with an adhesive/sealant. 
          This primer improves adhesion to the pinch weld and
          blocks ultraviolet light.

     206  CARBON ADSORPTION:  A carbon unit that is typically
          either a fixed-bed or a fluidized-bed design.  VOC-laden
          air is pretreated, if necessary, to remove any solids,
          liquids, and long-chain, high-boiling organic compounds
          that might coat the carbon.  The exhaust stream then
          passes through the adsorbing bed where the VOCs collect
          on the surface of the carbon.

     207  CATALYTIC INCINERATOR:  An incinerator that requires a
          catalyst to promote the oxidation of the VOCs at a lower
          temperature.  The catalyst is often, but not always, a
          platinum serial metal deposited in a porous form onto a
          structure, such as a honeycomb, or pellets.  The VOCs are
          preheated up to 650 to 900 oF and then enter the catalyst
          area.  There the oxidation of the VOCs continue to
          produce an increase in temperature across the catalyst
          bed.

     208  CERAMIC TILE INSTALLATION ADHESIVE:  Any adhesive that is
          intended by the manufacturer to be used for installation
          of ceramic tiles.

     209  CONTACT ADHESIVE:  Any adhesive that is intended by the
          manufacturer to adhere to itself instantaneously upon
          contact.  This adhesive is applied to both adherends and
          allowed to become dry, which develops a bond when the
          adherends are brought together without sustained
          pressure.  For the purpose of this rule, products that
          qualify as a contact adhesive using the above definition,
          and that are labelled exclusively for only one of the
          following applications shall not be required to meet the
          VOC limit for "Contact Adhesives" in Section 301:

          a.   Single-ply roofing material installation
          b.   Bonding of immersible products
          c.   Bonding of flexible vinyl to flexible vinyl

     210  COVE BASE INSTALLATION ADHESIVE:  Any adhesive that is
          intended by the manufacturer to be used for cove base
          installation.

                         c.   Cyclic, branched, or linear,
                              completely fluorinated tertiary
                              amines with no unsaturations.
                         d.   Sulfur-containing perfluorocarbons
                              with no unsaturations and with
                              sulfur bonds only to carbon and
                              fluorine.

          Perfluorocarbon compounds will be assumed to be absent
          from a product or process unless a manufacturer or
          facility operator identifies the specific individual
          compounds (from the broad classes of perfluorocarbon
          compounds) and the amounts present in the product or
          process and provides a validated test method which can be
          used to quantify the specific compounds.

     212  FLEXIBLE VINYL:  Nonrigid polyvinyl chloride plastic with
          at least five percent, by weight, of plasticizer content. 
          A plasticizer is a material, such as a high-boiling point
          organic solvent, that is incorporated into an adhesive to
          increase its flexibility, workability, or distensibility,
          and may be determined using ASTM Method E260-91 or from
          product formulation data.

     213  FLOOR COVERING INSTALLATION ADHESIVE:  Any adhesive that
          is intended by the manufacturer to be used for the
          installation of wood flooring, linoleum, indoor carpet,
          outdoor carpet, resilient tile, or artificial grass.

     214  GRAMS OF VOC PER LITER OF ADHESIVE, LESS WATER, LESS
          EXEMPT ORGANIC COMPOUNDS:  The VOC content in adhesives
          excluding water and exempt organic compounds shall be
          calculated using the following equation:

          Grams of VOC per liter       Ws - Ww - Wes
          of adhesives less water,  =  --------------
          less exempt compounds        Vm - Vw - Ves
     
     
     Where:     Ws =  weight of valatyile compounds (grams)
                Ww =  weight of water (grams)
                Wes=  weight of exempt organic compounds (grams)
                Vm =  volume volume of material (liters)
                Vw =  volume of water (liters)
                Ves=  volume of exempt organic compounds (liters)
     
     
     215  GRAMS OF VOC PER LITER OF MATERIAL:  The weight of VOC
          per volume of material shall be calculated using the
          following equation:

        Grams of VOC per liter 
                of material     =  Ws - Ww - Wes
                                   --------------
                                         Vm

        Where:  Ws =  weight of valatyile compounds (grams)
                Ww =  weight of water (grams)
                Wes=  weight of exempt organic compounds (grams)
                Vm =  volume volume of material (liters)
     
     
     216  GUN WASHER:  Electrically or pneumatically operated
          system that is designed to clean spray application
          equipment and minimize emissions.  A gun washer may also
          be considered a gun cleaning system that consists of
          spraying solvent into an enclosed container using a snug
          fitting.
     217  HOUSEHOLD ADHESIVE:  Any adhesive subject to Article 2,
          Consumer Products, Title 17 of the California Code of
          Regulations.  Household adhesives do not include units of

                    Coatings from the South Coast Air Quality
                    Management District's "Laboratory Methods of
                    Analysis for Enforcement Samples" manual.

          501.4     The VOC content of any plastic pipe welding
                    cement adhesive or primer shall be determined
                    using Proposed SCAQMD Laboratory Method of
                    Analysis for Enforcement Samples, Method 316a.

          501.5     The capture and control efficiency in Section
                    308 shall be determined using methods in 40
                    CFR 52.741 (a)(4)(iii) - Capture System
                    Efficiency Test Protocols, (a)(4)(vi) -

          501.6     The composite vapor pressure of organic
                    compounds in cleaning materials shall be
                    determined by quantifying the amount of each
                    compound in the blend using gas
                    chromatographic analysis (ASTM E260-91) for
                    organics and ASTM Method D3792-79 for water
                    content, if applicable, or by using product
                    formulation data, and by summing the partial
                    pressures of each compound at 20 oC.  For the
                    purpose of this calculation, Raoult's Law
                    applies to the blend.  The vapor pressure of
                    each single component compound may be
                    determined from ASTM D2879-86 or may be
                    obtained from a published source approved by
                    the APCO, such as the sources referenced in 40
                    CFR 52.741.

          501.7     The active and passive solvent losses from
                    spray gun cleaning systems shall be determined
                    using SCAQMD's "General Test Method for
                    Determining Solvent Losses from Spray Gun
                    Cleaning Systems" dated October 3, 1989.  The
                    test solvent for this determination shall be
                    any lacquer thinner with a minimum vapor
                    pressure of 105 mm of Hg at 20 oC, and the
                    minimum test temperature shall be 15 oC.
