For fine chemical standards, GB and HG are to be followed – so can SH be used?
Thread Content
Fine chemicals comply with GB HG; then can SH be used? Are there separate standards of one’s own?
Fine chemicals also fall under the category of chemical products, and therefore must comply with the HG standards.
SH can be used; generally, SH is more stringent than HG.
A specification for fine chemicals has now been issued
Fire Protection Standards for Engineering Design of Fine Chemical Enterprises GB51283-2020
Generally, **both shifting blame to general guidelines and to experts involve using the strictest provisions in the applicable standards**
The Fire Protection Design Standard for Fine Chemical Enterprises GB51283-2020 is a newly issued regulation; strictly speaking, it is not as comprehensive as the previous Fire Protection Design Standard for Petrochemical Enterprises GB50160-2008. However, it raises the standards in certain areas, and where project construction conditions permit, all recommendations marked as “preferable” should be taken into consideration. The GB category is essential; for other designs, it is recommended to use the HG category. Additionally, NB categories from other specialized fields should also be considered for selection. In this regard, it is necessary to take into comprehensive consideration local requirements, those of the design institute, and the basic conditions of the factory.
The SH specification can be used, but it is more stringent
