ISO 19085-10:2018 gives the safety requirements and measures for displaceable building site saws, designed to cut wood and materials with similar physical characteristics to wood, hereinafter referred to as "machines". NOTE 1 For the definition of displaceable machine, see ISO 19085‑1:2017, 3.5. ISO 19085-10:2018 deals with all significant hazards, hazardous situations and events as listed in Clause 4, relevant to the machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases have been taken into account. NOTE 2 For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010. The machine can also be fitted with a device for the saw blade to be manually raised and lowered through the table, whose hazards have been dealt with. This document does not apply to the following: a) machines with a maximum saw blade diameter smaller than 350 mm or greater than 500 mm; b) hand-held woodworking machines, including any adaptation permitting their use in a different mode, i.e. bench mounting; c) machines with a device to tilt the saw blade for angle cutting, machines with more than one saw blade rotational speed and machines equipped with a sliding table; NOTE 3 Hand-held motor-operated electric tools are covered by IEC 62841‑1 together with IEC 62841‑2‑5. NOTE 4 Machines with the device to tilt the saw blade for angle cutting, machines with more than one saw blade rotational speed and machines equipped with a sliding table are considered as table saws, covered by ISO 19085‑9. ISO 19085-10:2018 is not applicable to machines intended for use in potentially explosive atmospheres or to machines manufactured prior to the date of its publication.

Textiles - Seam tensile properties of fabrics and made-up textile articles - Part 2: Determination of maximum force to seam rupture using the grab method (ISO/DIS 13935-2:2025)

ISO 13935-2:2014 specifies methods for the determination of seam maximum force of sewn seams when the force is applied perpendicularly to the seam. ISO 13935-2:2014 describes the method known as the grab test. The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical or chemical treatment. It may be applicable to fabrics produced by other techniques. It is not normally applicable to geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns. The sewn fabrics may be obtained from previously sewn articles or may be prepared from fabric samples, as agreed by the parties interested in the results. This method is applicable to straight seams only and not to curved seams. The method is restricted to the use of constant rate of extension (CRE) testing machines.
