In the earlier revisions, moisture content of the timber used for manufacturing handles for brushes had been increased to 15 percent, use of tinplate had been prescribed instead of nickel-plated brass for the manufacture of fernules and excluded the use of brass pins. 0.2.1 In this third revision the measurement of the handle of sash tool brush has been corrected in accordance with the long standing trade practice to make the brush-head separately with the wedge in its proper place and then to fix the handle with the brush-head to complete the sash tool brush. The representation of length of handle outside the ferrule ( D ) has been modified accordingly in Fig. 1. 0.2.2 This type of brushes are generally used for painting window sashes and other narrow strips. 0.3 This standard contain clauses 4.1.6.1, 5.1 and 7.2 which call for agreement between the indentor or inspection authority and the supplier. 0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expres sing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. *Rules for rounding off numerical values ( revised ). 3 IS : 486 - 1983 1.
