This part of ISO 1924 specifies a method for measuring the tensile strength, strain at break and tensile energy absorption of paper and board, using a testing machine operating at a constant rate of elongation (20 mm/min). This part of ISO 1924 also specifies equations for calculating the tensile index, the tensile energy absorption index and the modulus of elasticity. Testing in conformance with this part of ISO 1924 always includes the measurement of tensile strength. Measurement or calculation of other properties is subject to agreement between the parties concerned. This part of ISO 1924 is applicable to all papers and boards, including papers with a high strain at break if the results are within the capacity of the testing machine. It also applies to the components of corrugated board but not, however, to corrugated board itself. This part of ISO 1924 is not applicable to tissue paper and tissue products for which ISO 12625-4[2] is applicable. For the determination of tensile properties of laboratory sheets, ISO 5270[3] is recommended.

ISO 12625-8:2010 specifies a basket-immersion test method for the determination of water-absorption time and water-absorption capacity of tissue paper and tissue products. It is expressly stated that the detection of impurities and contraries in tissue paper and tissue products be applied according to ISO 15755. For the determination of moisture content in tissue paper and tissue products, ISO 287 is applicable.

This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of composite gas cylinders and tubes for compressed hydrogen. NOTE 1 Unless specified in the text, for the purposes of this document, the word “cylinder” includes tubes. This document applies to - fully wrapped composite cylinders (Type 3 and Type 4) - hoop wrapped cylinders (Type 2) with carbon fibres intended to be permanently mounted in a frame (e.g. bundle or trailer) with a test pressure of not less than 300 bar, with: — non-metallic liners (for Type 4) or seamless metallic liners (for Type 2 and Type 3), — a maximum water capacity of 3 000 l — a maximum working pressure of 1 000 bar. — the product of working pressure times water capacity (p x V) not exceeding 1 000 000 bar.l. NOTE 2 A glass fibre protective layer is sometimes applied to the external surface of the cylinder

This document specifies a method for the determination of the viscosity number of dilute solutions of polyamides in certain specified solvents. The method is applicable to the polyamides designated PA 46, PA 6, PA 66, PA 69, PA 610, PA 612, PA 11, PA 12, PA 6T/66, PA 6I/6T, PA 6T/6I/66, PA 6T/6I, PA 6I/6T/66 and PA MXD6 as defined in ISO 16396-1, as well as to copolyamides, compounds of polyamides and other polyamides that are soluble in one of the specified solvents under the specified conditions. The method is not applicable to polyamides produced by anionic polymerization of lactams or produced with cross-linking agents; such polyamides are normally insoluble in the specified solvents. The viscosity number is determined by the general procedure specified in ISO 1628-1, observing the particular conditions specified in this document.
