The present revi sion has been undertaken to include the definition of ambient temperature, changing the requirement of shelf life and improving the test for consistency. The use of aluminium foil/waxed paper has also been made recommendatory only. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 'Rules for rounding off numerical values ( revised ). AMENDMENT NO. 1 AUGUST 1993 TO IS 1746 : 1992 SHOE POLISH, PASTE — SPECIFICATION ( Third Revision ) ( Second cover page, Foreword ) — Considering the international trade practices, on marking of polishes, the word paste is being deleted from the marking clause. It is, bowever, retained in the title to indicate its physical state. [Page 2, clause 6.1 (c)] — Delete the word 'PASTE' wherever it occurs.
