This standard was first published in 1986 based on ISO 4115 : 1980. The first revision of this standard has been undertaken with a view to bring it in line with the latest version of ISO 4115 : 1997. The text of ISO Standard 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. 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: International Standard Corresponding Indian Standard Degree of Equivalence ISO 4117 : 1993 Air and air/land cargo IS 11499 : 1996 Air and air/land cargo Identical pallets – Specification and testing pallets – Specification and testing (first revision) The technical committee has reviewed the provisions of the following International Standards referred in this adopted standard and has decided that they are acceptable for use in conjunction with this standard: International/Other Title Standard ISO 7166 : 1985 Aircraft – Rail and stud configuration for passenger equipment and cargo restraint ISO 8097 : 1993 Aircraft – Minimum airworthiness requirements and test conditions for certified air cargo unit load devices ISO/TR 8647 : 1990 Environmental degradation of textiles used in air cargo restraint equipment ISO 9788 : 1990 Air cargo equipment – Cast components of double stud fitting assembly with a load capacity of 22 250 N (5 000 lbf), for aircraft cargo restraint IATAUnit Load Devices (ULD) Technical Manual Sizes and units used in this adopted ISO Standards are both in SI and FPS system. The Committee recommended using only SI system. 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.
