RH4 & RH5 Compounds (100 ng/m3 target)
Thread Content
How should we understand \"target\" here? Standard? Goal? Indicators?
I can’t think of a more appropriate term than “indicator value”.
It is estimated that these two compounds are likely to be toxic. Using ng/m3 as the unit for estimation likely refers to the concentration in the air. Personally, I think 100 ng/m3 here refers to the limit that needs to be controlled.
“As I expected, the “target values” are indeed RH4 and RH5, which are the classification standards used within the customer’s company. These two types of compounds are highly toxic, so special care must be taken when handling them; otherwise, one could poison themselves. When translating such materials, you should look up more information on industrial hygiene.
