Scope

GB/T 39243-2020 is the English-translated version of 船用生物可溶性矿物棉制品技术要求及试验方法.

GB/T 39243-2020 specifies the technical requirements and test methods for marine biosoluble mineral wool products.

Clause 1 states that it is applicable to the manufacture and acceptance of bio-soluble mineral wool products used for fire resistance and thermal insulation in ships and marine engineering, a sentence the page's summary field repeats; no exclusions are recorded.

Clause 3 takes its terms and definitions from EN 1094-1:2008 and adds one of its own, biosoluble mineral wool, defined as alkaline earth silicate cotton of low biological persistence prepared by the high temperature melting method, with a note that it is also known as low-biopersistence alkaline earth silicate cotton.

Clause 4, whose heading on the page is simply 'categories', classifies biosoluble mineral wool products according to their morphological characteristics, but the draft breaks off at that sentence, so the categories themselves and everything after clause 4 are not shown, and the page prints no table of contents for this standard.

Clause 2 cites GB/T 10294, GB/T 11835, GB/T 13480, GB/T 17911-2018, GB/T 20313, GB/T 21114, ISO 22262-1, EN 1094-1:2008, the 2010 International Fire Test Procedure Application Rules (2010 FTP Rules) and EUR 18748 EN (1999).

The page states that the standard was proposed and is managed by the National Ocean Shipping Standardization Technical Committee (SAC/TC12). It carries the Chinese classification U05 and the international classification 47.020.05, and the page estimates its length at 8,892 words.

The page does not state that it replaces an earlier edition; it was issued on November 19, 2020 and has applied since June 1, 2021.
