FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Flooring,
WallFinishing andRoofing Sectional Committee hadbeen approved bytheCivilEngineering Division Counci1.
This standard has been formulated with aviewto laying down anew specification for pitch-mastic flooring for
area where heavy hydrocarbon products like kerosene, diesel oil, furnace oil are handled. This standard will
alsobeapplicable to petrol pumps, dieseldepot oflargeconsumer oftheseproducts aswell asfactories handling
hydrocarbon products. It isalso applicable to road surfaces prone to oil spillage by automobiles.
The composition of the Committee responsible for formulation of this standard is given at Annex E.
For the purpose of deciding whether aparticular requirement of this standard iscomplied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
[S2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in
the rounded off value should be the same asthat of the specified value inthis standard.
