ROHS Substances table 90 ROHS Name CAS TWAEV STEV Ceiling (mg/m³) Notes Sampling Device Flow L/min Volume TWAEV STEV (L) Principle MRV µg CVa (%) # meth. Remarks Isophorone diisocyanate 4098-71-9 0,045 EM S Millipore AP4003705 glass fiber filter pretreated in the laboratory in series with a Teflon filter #MSI Z50WP03700 917 PTF filter GF filter Vial 1 HPLC-UV- 0,038 Flu 15 IRSST 376 Refer to the sampling guidelines supplied with the equipment. If more than one isocyanate is requested, provide a process sample. The two filters in the sampling cassette allow specific analysis of monomer HDI in vapour form and in aerosol form. The result supplied in the report is the sum of the monomers of IPDI of the two fractions. Determination of the corresponding oligomers is also done during the analysis. HDI can be determined simultaneously on the same sample. Note that the analytical method does not differentiate IPDI oligomers from HDI oligomers. The sampling time can be longer than 15 minutes if the IPDI is present in vapour form only. Isopropoxyethanol 109-59-1 106 Pc Activated charcoal tube 100/50mg 0,1 10 GC-FID OSHA 07 Contact the IRSST before sampling. OSHA method 07 is for organic vapours and can be adapted to isopropoxyethanol. Isopropyl acetate 108-21-4 1040 1290 SKC 226-01 activated charcoal tube 2120 Activated charcoal 100/50 mg Max: 0,2 10 3 GC-FID 475 IRSST 279-1 The analysis can be done by gas chromatography coupled with mass spectrometry (GC-MS, IRSST method #369); in this case the analytical uncertainty (CVa) is 0.74%. Isopropyl alcohol 67-63-0 983 1230 3M 3500 organic vapour monitor 2695 Passive dosimeter 0,0394 GC-FID 100 5,0 IRSST 93-1 For the monitors, the flow must be considered as being a sampling rate. According to the data from 3M, the precision (CVsampling) of the sampling rate is 5%. Refer to the 3M passive monitor guide on the IRSST's Web site. Isopropyl alcohol 67-63-0 983 1230 SKC 226-01 activated charcoal tube 2120 Activated charcoal 100/50 mg Max: 0,2 3 3 GC-FID 100 5,0 IRSST 93-1 The analysis can be done by gas chromatography coupled with mass spectrometry (GC-MS, IRSST method #369); in this case the analytical uncertainty (CVa) is 4.8%. Isopropyl glycidyl ether (IGE) 238 356 Activated charcoal tube 100/50 mg 0,01- 0,2 30 3 GC-FID NIOSH 1620 Contact the IRSST before sampling. 4016-14-2 Isopropylamine 75-31-0 12 24 Impregnated glass fiber filter, Millipore AP4003705 955 Impregned FGF 1 HPLC-MS 9 15 IRSST 363 Aniline, diethanolamine, dimethylamine, ethanolamine, isopropylamine, methylamine and morpholine can be sampled at the same time. N-Isopropylaniline 768-52-5 11 Pc Two glass fiber filters impregnated with 1 100 HPLC-UV OSHA 78 sulfuric acid. Contact the IRSST before sampling.
ROHS Substances table 91 ROHS Name CAS TWAEV STEV Ceiling (mg/m³) Notes Sampling Device Flow L/min Volume TWAEV STEV (L) Principle MRV µg CVa (%) # meth. Remarks Kaolin 1332-58-7 5 Pr SKC 225-8-01-1 or 225-8-04 polyvinyl 1,7 180 Grav 25 4,9 IRSST 48-1 chloride filter (nylon) 902 914 PVC filter-37 PVC filter-25 2,75 (GS3) 997 PVC filter-37, 3 parts Additional information is available in Info-Labo 91-03. The weight measurement method for dusts is by definition non-specific. Ketene 463-51-4 0,86 2,6 Glass fritted tip impinger containing 10 mL of hydroxylammonium chloride 1 50 Colo 15 NIOSH S92 An impinger containing toluene and placed ahead of the main impinger can minimize the interference of the acetic anhydride. Contact the IRSST before sampling. Any compound containing an R-CO group such as esters, acid chlorides and anhydrous acids may cause interference. L.P.G. (Liquified petroleum gas) 68476-85-7 1800 DRI-IR OSHA IMIS1803 Contact the IRSST before sampling. Lead and inorganic compounds 7439-92-1 0,05 C3 Mixed cellulose ester filter, 0.8µm, 25 and 1,5 180 ICP-MS 0,1 2,86 IRSST 362 37 mm. 905 MCE filter-37 915 MCE filter-25 Cassettes 913 or 916, whose filters are preweighed, can also be used. For surface wipe sampling, contact Laboratory Customer Service. The analytical results are expressed as total lead. Lead arsenate (as Pb3(AsO4)2) 3687-31-8 0,15 Mixed cellulose ester filter 2 960 ICP-MS OSHA ID121 Contact the IRSST before sampling. Method ID121 is for lead and can be adapted to this product. Lead chromate (as Cr) 7758-97-6 0,012 C2 RP EM PALL CA28149-306 vinyl/acrylic copolymer filter 926 Vinyl/acrylic copolymer filter 1,5 à 4 360 IC-VIS 0,04 4,4 IRSST 365 For surface wipe sampling, contact Laboratory Customer Service. The analytical results are expressed as total water-insoluble chromium VI. Surface tests for chromates can be carried out, and the required equipment (kit #2625) is available at the IRSST. See communiqué 2008-06 on our Web site. Analysis time of 8 days for welding fumes and 10 days for the other processes following the sampling date. Ship all samples by rapid courier within a period not exceeding 24 hours after sampling. Any substance that produces a response on the detector at 540 nm and that has a retention time similar to Cr VI is a potential interference. Lead tetraethyl (as Pb) 78-00-2 0,05 Pc XAD-2 tube 0,01-1 120 GC-PID NIOSH 2533 Contact the IRSST before sampling. Lead tetramethyl (as Pb) 75-74-1 0,05 Pc XAD-2 tube 0,01- 24 GC-PID NIOSH 2534 0,2 Contact the IRSST before sampling.
