Such chains are not suitable for use with lifting appliances as defined in DIN 15 003.nor tor being subjected to static loads.To facilitate comparison with the customary chain designations used in the past (*A (short/and 'C (long)*), these have been included in the table below.Chain DIN 5685 - G 4 x 19Continued on page 2DIN 5685 Engl.

The tolerances on nominal size (about ±5%) have bean brought into line with other chain standards.The values specified for pitch have not been changed, their limit deviatlons also being about ±5% and given to the nearest Viomm.Specifications for outside width have been deleted. In keeping with DIN 763. an inside width equal to about 1,8 d has been in・ eluded, which agrees with the dimensions specified for long-link chains in that standard・ with the exception of sizes below 4 mm and size 12 mm.As a measure of deformability.the elastic limit has been introduced The values specified are calculated values which must not be exceeded, since permanent deformation would otherwlse result.
