This document describes a classification of non-metallic blast-cleaning abrasives for the preparation of steel substrates before application of paints and related products. It specifies the characteristics which are required for the complete designation of such abrasives. This document applies to abrasives supplied in the "new" or unused condition only. It does not apply to abrasives either during or after use. NOTE Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504‑2.

This document specifies the requirements for qualification testing of welders for fusion welding of steels, aluminium, copper, nickel, titanium and zirconium.

In this document, the terms "aluminium", “copper”, “nickel”, “titanium” and “zirconium” refer to the materials and their alloys.

This document provides a set of technical rules for a systematic qualification test of the welder and enables such qualifications to be uniformly accepted independently of product type, location and examiner or examining body.

When qualifying welders, the emphasis is placed on the welder's ability to manually manipulate the electrode, welding torch, welding blowpipe, or laser gun, with or without filler material, to produce a weld of acceptable quality.

The fusion welding processes referred to in this document include welding processes which are designated as manual or partly mechanized.

This document does not cover fully mechanized and automated welding processes which are covered by ISO 14732.

The principles of this document can be applied to other fusion welding processes.

This document specifies test methods for the determination of the percentage of defective particles and of the microstructure of metallic blast-cleaning abrasives. This is one of a number of parts of ISO 11125 dealing with the sampling and testing of metallic abrasives for blast-cleaning. The types of metallic abrasive and requirements on each are contained in the various parts of ISO 11124. The ISO 11124 and ISO 11125 series have been drafted as a coherent set of International Standards on metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.

This document gives guidelines for prevention of hydrogen assisted brittle fracture resulting from the manufacturing process (internal hydrogen embrittlement (IHE)). This document is applicable for parts or components made of high strength steels. It also advises on the relationship between material selection, manufacture including heat treatment, and coating.

This International Standard specifies the requirements and/or measures to eliminate the hazards or reduce the risks in the following groups of stationary grinding machines which are designed primarily to shape metal by grinding: Group 1: Manually controlled grinding machines without power operated axes and without numerical control. Group 2: Manually controlled grinding machines with power operated axes and limited numerically controlled capability, if applicable. Group 3: Numerically controlled grinding machines. NOTE 1 For detailed information on the groups of grinding machines, see the definitions in 3.1 and 3.4. NOTE 2 Requirements in this International Standard are, in general, applicable to all groups of grinding machines. If requirements are applicable to some special group(s) of grinding machines only, then the special group(s) of grinding machine(s) is/are specified. This International Standard covers the significant hazards listed in Clause 4 and applies to ancillary devices (e.g. for workpieces, tools and workpiece clamping devices, handling devices), which are integral to the machine. This International Standard also applies to machines which are integrated into an automatic production line or grinding cell inasmuch as the hazards and risks arising are comparable to those of machines working separately. This International Standard also includes in Clause 7 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 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). Where additional metalworking processes (e.g. milling, turning, laser processing) are involved, this International Standard can be taken as a basis for safety requirements. For specific information on hazards arising from other metalworking processes, which are covered by other International Standards, see the Bibliography. This International Standard applies to machines that are manufactured after the date of issue of this International Standard. This International Standard does not apply to stationary honing, polishing and belt grinding machines and not to transportable motor-operated electric tools in accordance with IEC 61029-2-2 and IEC 61029-2-10.

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. — Group 1: Manually controlled turning machines without numerical control. — Group 2: Manually controlled turning machines with limited numerically controlled capability. — Group 3: Numerically controlled turning machines and turning centres. — Group 4: Single- or multi-spindle automatic turning machines. NOTE 1 For detailed information on the machine groups, see the definitions in 3.5, features and limitations in 5.1.1 and mandatory and optional modes of operation in 5.1.2.1. NOTE 2 Requirements in this International Standard are, in general, applicable to all groups of turning machines. If requirements are applicable to some special group(s) of turning machines only, then the special group(s) of turning machine(s) is/are specified. NOTE 3 The automatic exchange of clamping devices are excluded from this standard 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 (see 4). 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.
