This document specifies a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionization detection. The document is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature, and which have a boiling range of at least 100 °C. The document is applicable to materials with initial boiling points (IBP) above 100 °C and final boiling points (FBP) above 750 °C, for example, heavy distillate fuels and residuals. The method is not applicable to bituminous samples. The test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphthas, reformates, gasolines) or middle distillates like Diesel and Jet fuel. Petroleum or petroleum products containing blending components, which contain hetero atoms (for example alcohols, ethers, acids, or esters) or residue, are not to be analysed by this test method. NOTE For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction. WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

Metalinės medžiagos. Tempimo bandymas. Mažesnio kaip 0,200 mm vardinio storio metalinės folijos ir juostų tempimo bandymas naudojant kompiuterizuotas bandymo mašinas

This document specifies a method for tensile testing of test pieces of foil and strip of metals with a nominal thickness less than 0,200 mm by using computer-controlled testing machines. The used test pieces according to this document are rectangular (parallel sided strips) and are prepared by cutting. This method is used to determine typically the proof strength, Rp0,2, the tensile strength, Rm, the percentage plastic extension at fracture, Ax mm, (using the automatic determination by the machine) or the (plastic) elongation after fracture, Ax mm, (by manual determination). NOTE 1 The use of a computer-controlled tensile testing machine is important to apply parameters and fulfil several procedures. NOTE 2 EN ISO 6892 1:2019 Annex B specifies test pieces (shape, dimensions, preparation, determination of the original cross-sectional area) for thin products flats between 0,1 mm and 3 mm thickness. EN ISO 6892 1:2019 Clause B.1 specifies requirements for products of less than 0,5 mm thickness, which can require special precautions. NOTE 3 This document and EN ISO 6892 1:2019 Annex B both apply to products of thickness between 0,1 mm and 0,2 mm. For further information, see Clause 5.
