IS 12726 : 2024/ISO 22915-21 : 2019 Industrial Trucks - Order-Picking Trucks with Operator Position Elevating Above 1 200 mm - Verification of Stability
NATIONAL FOREWORD
This Indian Standard (Second Revision) which is identical to ISO 22915-21 : 2019 'Industrial trucks - Verification of stability - Part 21: Order-picking trucks with operator position elevating above 1 200 mm' 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 1989. The first revision of this standard was undertaken to align it with ISO 22915-21 : 2009. This revision of the standard has been undertaken to align it with ISO 22915-21 : 2019.
The main changes incorporated in this standard are as follows:
a) The wording of 4.2.3 is revised editorially for better comprehensibility;
b) An additional stability test for creep speed is added to Table 1, tests 3 and 4;
c) The explanatory note to the maximum travel speed is adapted to the state of the art; and
d) 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 standards published on this subject are as follows:

The text of 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.
