TIÊU CHUẨN JIS K 0108 : 2010 (JSAC/JSA) - Phương pháp xác định hydro sunfua trong khí thải

This translation has been made based on the original Japanese Industrial Standard revised by the Minister of Economy, Trade and Industry through deliberations at the Japanese Industrial Standards Committee as the result of proposal for revision of Japanese Industrial Standard submitted by The Japan Society For Analytical Chemistry (JSAC)/Japanese Standards Association (JSA) with the draft being attached, based on the provision of Article 12 Clause 1 of the Industrial Standardization Law applicable to the case of revision by the provision of Article 14. 

Consequently JIS K 0108: 1983 is replaced with this Standard.
