Searching for a standard specification for glass tube level gauges
Thread Content
The last edit to this post was made by ds66616 on 2018-9-22 at 22:23; it states in one of the inspection requirements that \"glass tube level gauges should be equipped with protective sleeves\"； \"Glass tube level gauges should not be used for flammable and explosive liquids.\" This requirement is actually easy to understand. However, a standard is specified after this requirement: \"(Article 4.11.2 of AQ5204)\.\" In an attempt to find this standard, searches on the Internet yielded only the Safety Technical Regulations for Paint Manufacturers AQ 5204-2008, which does not contain any Article 4.11.2. I would like to ask whether it might be a mistake made by the person who formulated these inspection requirements? What is the correct standard number? Could you help find it?
It is likely that an expert made a mistake; the \"Safety Technical Regulations for Coating Manufacturers AQ5204-2008\" specifies as follows: 4.10.2 Flammable liquids should not use glass tube level gauges. When using a glass tube level gauge, protective measures such as sleeves should be employed.
I see, it was my own carelessness. Thank you for the help:handshake
Yes, there are no mandatory standards prohibiting the use of glass level gauges
