This International Standard specifies the requirements and/or measures to eliminate the hazards or reduce the risks in the following groups of turning machines and turning centres, which are designed primarily to shape metal by cutting. This international standard takes account of intended use, including reasonably foreseeable misuse, maintenance, cleaning, and setting operations. It specifies access conditions to operators positions and manual load/unload stations. It presumes accessibility to the machine from all directions. It describes means to reduce risks to operators and other exposed persons. This international standard also applies to workpiece transfer devices including transport devices for loading/unloading when they form an integral part of the machine. This international standard deals with significant hazards relevant to turning machines when they are used as intended and under the conditions foreseen by the manufacturer. Risk analysis of hazards arising from other metal working processes (e.g. grinding, milling, friction welding, forming, electro discharge, laser processing) are covered by other standards (see Bibliography). However, if additional milling and grinding operations are provided hazard arising from additional clamping condition and ejection of parts shall be considered. This International Standard also applies to machines which are integrated into an automatic production line or turning cell in as much as the hazards and risks arising are comparable to those of machines working separately. This International Standard also includes a minimum list of safety-relevant information which the manufacturer has to provide to the user. See also ISO 12100:2010, Figure 2, which illustrates the interaction of manufacturer's and user's responsibility for the operational safety. The user's responsibility is to identify specific hazards (e.g. fire and explosion) and reduce the associated risks can be critical (e.g. whether the central extraction system is working correctly). This International Standard applies to machines that are manufactured after the date of issue of this International Standard.

 

This part of ISO 148 specifies the Charpy (V-notch and U-notch) pendulum impact test method for determining the energy absorbed in an impact test of metallic materials. This part of ISO 148 does not cover instrumented impact testing, which is specified in ISO 14556[1]. Annexes B and C are based on ASTM E23[2] and are used with the permission of ASTM International, 100 Barr Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428-2959, USA.

 

This part of ISO 148 covers the verification of pendulum-type impact testing machines, in terms of their constructional elements, their overall performance and the accuracy of the results they produce. It is applicable to machines with 2 mm or 8 mm strikers used for pendulum impact tests performed in accordance with ISO 148-1. It can be applied to pendulum impact testing machines of various capacities and of different design. Impact machines used for industrial, general or research laboratory testing of metallic materials in accordance with this part of ISO 148 are referred to as industrial machines. Those with more stringent requirements are referred to as reference machines. Specifications for the verification of reference machines are found in ISO 148-3. This part of ISO 148 describes two methods of verification. A pendulum impact testing machine is not in compliance with this part of ISO 148 until it has been verified by both the direct and indirect methods and meets the requirements of Clause 6 and Clause 7. This part of ISO 148 describes how to assess the different components of the total energy absorbed in fracturing a test piece. This total absorbed energy consists of

 

This part of ISO 148 specifies the requirements, preparation and methods for qualifying certified reference test pieces used for the indirect verification of pendulum impact testing machines in accordance with ISO 148-2. It specifies notched test pieces with nominal dimensions identical to those specified in ISO 148-1; however, the tolerances are more stringent.

This document specifies a method for quantitative determination of various perfluorinated hydrocarbons by means of High-Performance Liquid Chromatography (HPLC) and mass spectrometry in soil, sludge, sediment and waste (see Table 1). For many substances to which this document applies a limit of quantification (LOQ) of 0,1 to 10 µg/kgdm can be achieved. See also Annex D for more information regarding the LOQ’s reachable. The method can be applied to the analysis of additional PFAS not specified in the scope, if validity is proven by proper in-house validation protocols, particularly for volatile compounds that may be lost during preparation. For each target compound all, branched and non-branched are quantified together. In this method the amount of linear and branched PFAS is quantified using the response factor of the linear PFAS in the calibration standard and the total area of the linear and branched PFAS (Annex C gives more explanation). Alternatively, the linear isomer and sum of branched isomers may be quantified separately and the sum of both can be calculated provided a complete separation of the linear isomer from the branched isomers is obtained. All compounds of Table 1 were tested during an international inter laboratory trial in Europe in the period December 2023 to April 2024. The table specifies for which the criteria of an interlaboratory standard deviation (CVR) of 50 % was not reached. See Annex D for more details. The validity of the procedure has been proven for soil, sediment and sludge samples and for a selection of waste samples. For other waste types than mentioned in Annex D the laboratory shall validate the suitability of the procedure of this standard.
