Standard specification download
Thread Content
I would like to ask everyone: are there any more professional websites where I can download the standards and specifications used in chemical engineering design, such as GB, SH, SY, JB, etc.? Paid options are also available, as searching on Baidu usually takes a long time and many files cannot be downloaded. I’d appreciate it if you could recommend some options; thank you very much! :P
There are many in Haichuanli; if that doesn’t work, use Gongbiao.com
It’s available in most bookstores, but if you use it frequently, it’s better to buy the paper version as it’s more convenient for flipping through and making notes
http://www.zbgb.org/index.html can basically be found there
http://www.sac.gov.cn/ and http://openstd.samr.gov.cn/bzgk/gb/std_list_type?r=0.8552442814744007&page=1&pageSize=50&p.p1=1&p.p6=75&p.p90=circulation_date&p.p91=desc – these two websites can be used to check the information
