This standard has been prepared in supercession to the earlier Indian Standard IS 10936: 1984/ ISO 569:1982 ‘Co-ordinated dimensions of heald frames in relation to the pitch of the harness’ since ISO 10787 published in three parts cancels and partially replaces ISO 569:1982 on which IS 10936:1984 was based. This standard consists of three parts under the general title Textile machinery and accessories — Heald frames: )I ,‘, .-1 .’ Part 1 Heald-carrying rod fixed to the frame stave by rod support — Coordinated dimensions Part 2 Heald-carrying rod fixed directly on the frame stave — Coordinated dimensions Part 3 Guides for heald frames In this standard, the text of ISO Sandard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’. b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker. CROSS REFERENCE In this adopted standard reference appears to the following International Standard for which Indian Standard also exists. The corresponding Indian Standard which is to be substituted in its place, is . listed below along with its degree of equivalence for the edition indicated. However, that International Standard cross-referred in this adopted ISO Standard, which has subsequently been revised, position in respect of that latest ISO Standard has been given: International Standard Corresponding Indian Standard Degree of Equivalence ISO 2768-1 : 1989 General tolerances IS 2102 (Part 1) : 1993 General Identical — Part 1 : Tolerances for linear and tolerances: Part 1 Tolerances for linear angular dimensions without individual and angular dimensions without individual tolerance indications tolerance indications 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)’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
