ISO 15011-5:2011 溶接および関連プロセスの健康と安全性—ヒュームおよびガスをサンプリングするための実験室方法—パート5：熱分解-ガスクロマトグラフィー-質量分析を使用して、全体または一部が有機材料で構成される製品を溶接または切断するときに生成される熱分解生成物の識別 | ページ 6

3.1

chemical agent

any chemical element or compound, on its own or admixed, as it occurs in the natural state or as produced, used or released, including release as waste, by any work activity, whether or not produced intentionally and whether or not placed on the market

[SOURCE: Council Directive 98/24/EC ^[7] , Art. 2(a)]

3.2

occupational exposure limit value

limit of the time-weighted average of the concentration of a chemical agent in the air within the breathing zone of a worker in relation to a specified reference period

[SOURCE: Council Directive 98/24/EC ^[7] , Art. 2(d)]

Note 1 to entry: Limit values are mostly set for reference periods of 8 h, but can also be set for shorter periods or concentration excursions. Limit values for gases and vapours are stated in terms independent of temperature and air pressure variables in millilitres per cubic metre and in terms dependent on those variables in milligrams per cubic metre for a temperature of 20 °C and a pressure of 101,3 kPa. Limit values for airborne particles as well as mixtures of particles and vapours are given in milligrams per cubic metre or multiples of that unit for actual environmental conditions (temperature, pressure) at the workplace. Limit values of fibres are given in number of fibres per cubic metre or number of fibres per cubic centimetre for actual environmental conditions (temperature, pressure) at the workplace.

3.3

shop primer

material that is applied to an unpainted metal surface for protective purposes, which does not have to be removed prior to welding and does not prevent the making of an acceptable weld

Note 1 to entry: Shop primers are typically applied with a thickness of between 15 µm and 30 µm.

3.4

thin organic coating

material that is applied as a very thin film to an unpainted metal surface for protective purposes, which does not have to be removed prior to welding and does not prevent the making of an acceptable weld

Note 1 to entry: Thin organic coatings are typically applied with a thickness of between 1 µm and 3 µm.

3.5

weld-through adhesive

polymer that is applied prior to welding to a primed or unpainted metal surface for the purpose of bonding, which does not prevent the making of an acceptable weld

3.6

weld-through sealant

mastic, gap-filling material that is applied prior to welding to an unpainted metal surface for non-pressure sealing purposes, which does not prevent the making of an acceptable weld

3.7

weld-through oil

material composed of aliphatic and aromatic hydrocarbons that is applied to afford protection and act as a lubricant during pressing operations, which does not prevent the making of an acceptable weld

Note 1 to entry: The aromatic hydrocarbon content of weld-through oils is typically less than 10 % volume fraction.

3.8

weld-through wax

material composed of esterified fatty acids that is applied to afford protection and act as a lubricant during pressing operations, which does not prevent the making of an acceptable weld
