The State Enterprise \u201cLviv Research and Design Institute \u2018LvivbudmNDIproekt\u2019\u201d developed the national standard DSTU B V.2.7-241:2010 Building Materials. Rubble Stone. Technical Specifications<\/em> (hereinafter referred to as DSTU-241), which was adopted by Order No. 514 of the Ministry of Regional Development and Construction of Ukraine dated December 16, 2010, and entered into force on September 1, 2011.<\/p>\n\n\n\n

According to Clause 3.1 of Section 3 of DSTU-241, rubble stone is defined as \u201clarge lumps (pieces) of rock of arbitrary shape ranging in size from 80 mm to 1000 mm, obtained by crushing sedimentary rocks (anhydrite, magnesite, dolomite, tuff, shell rock, sandstone, conglomerate, carbonate breccia), igneous rocks (granite, syenite, diorite, gabbro), and metamorphic rocks (gneiss, marble, quartzite).\u201d<\/p>\n\n\n\n

Therefore, based on this definition, rubble stone may be produced exclusively from those sedimentary, igneous, and metamorphic rocks whose names are listed in parentheses in the definition (i.e., only from anhydrite, magnesite, … granite, syenite, … gneiss, marble), since the names of the specified rocks are not followed by the words \u201cetc.\u201d or \u201cand others,\u201d which does not allow the use of other rock types for the production of rubble stone.<\/p>\n\n\n\n

But what should be done in cases where rubble stone is produced from other igneous rocks, such as andesite, basalt, or diabase, whose names are absent from the definition of \u201crubble stone\u201d? And why does the definition of \u201crubble stone\u201d in Clause 3.1 of Section 3 of DSTU-241 contain only a partial list of sedimentary, igneous, and metamorphic rocks from which rubble stone may be produced? (In this regard, see DSTU B A.1.1-56-94 Standardization and Regulation System in Construction. Rocks for the Production of Non-Metallic Construction Materials. Terms and Definitions<\/em>.)<\/p>\n\n\n\n

According to Article 22 of the Law of Ukraine \u201cOn Standardization,\u201d national standards must be reviewed at least once every five years from the date of their adoption.<\/p>\n\n\n\n

There is no publicly available information regarding any review of DSTU-241 since it entered into force.<\/p>\n\n\n\n

At present, many of the regulatory documents referenced in Section 2, \u201cNormative References,\u201d of DSTU-241 require replacement with updated versions.<\/p>\n\n\n\n

For example, the following documents should have long ago been replaced:<\/p>\n\n\n\n
