IS 7631 : 2024/ISO 22915-4 : 2018 Industrial Trucks - Pallet Stackers, Double Stackers and Order-Picking Trucks with Operator Position Elevating up to and Including 1 200 mm Lift Height - Verification of Stability
NATIONAL FOREWORD
This Indian Standard (Third Revision) which is identical to ISO 22915-4 : 2018 'Industrial trucks - Verification of stability - Part 4: Pallet stackers, double stackers and order-picking trucks with operator position elevating up to and including 1 200 mm lift height' issued by International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Transport Tractors, Trailers and Industrial Trucks Sectional Committee and approval of the Transport Engineering Division Council.
This standard was first published in 1975 and then revised in 1993. This revision was undertaken to align it with ISO 5766 : 1990. Subsequently ISO 5766 : 1990 was withdrawn and published as ISO 22915-4 : 2009. The second revision was undertaken to align it with ISO 22915-4 : 2009. This revision of the standard has been undertaken to align it with ISO 22915-4 : 2018.
The main changes incorporated in this standard are as follows:
a) The wording of 4.2.3 is revised editorially for better comprehensibility; and
b) Several drawings in Table 1 are redrawn for better comprehensibility.
This standard is one of the standards on subject 'Industrial trucks - Verification of stability'. The other Indian Standards published on this subject are as follows:

The text of the ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and 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'; and
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.
