[Stoves] Particulate Matter Norms

[rajan_jiby at dataone.in]

Dear Crispin,

Bureau of Indian Standards ( BIS ) gives 2 mg/m3 as the upper limit for particulate matter ( PM ) emissions from a wood stove.

Could you please help me with the Norms set by WHO for PM from a wood stove ?  Are the Norms a little more liberal ?

Regards,

Rajan
