This document deals with all significant hazards, hazardous situations or hazardous events relevant to hand-held or hand-operated laser processing machines (HLMs), when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. HLM is the machine, as defined in ISO 11553-1:2020, 3.7, in which laser radiation is generated, where the laser provides sufficient energy/power to cause a phase transition in a part of the workpiece and where the laser output or workpiece to be processed is guided manually or hand-held during the laser material processing.
This document defines general design requirements of HLM. HLM includes the laser device, beam-guiding device (e.g. mirror, fibre, lenses), beam-shaping device (e.g. telescope, focusing), and controls. The laser assembly as an integral part of the HLM or only the laser processing head is hand-held or hand-operated during the laser material processing.
This document does not apply
— to laser processing machines which are remotely controlled by a manual controller (hand-operated controller), such as joy sticks, keyboard, etc., without touching a workpiece or a part mechanically connected with the laser material processing head by using the hand(s) of the operator (user)
— to laser processing machines without a drive system which may not belong to machinery. And the laser processing apparatus without moving parts, which may not be considered as machinery in “Type C standard”.
— to medical or cosmetic applications for the treatment of living human or animal tissue;
— to weapon applications, (e.g. such as with regard to military applications, direct close combat.)
NOTE “hand-operated laser processing machine” is synonymous with “hand-guided laser processing machine” in this document. Hand-operated laser processing machines often use manual force reduction means such as wheels, supports, etc., for manual positioning of the laser processing heads or the workpieces.
It is applicable to HLMs using laser radiation to process materials.
The purpose of this document is to draw attention to the hazards related to HLMs and to prevent personal injury. Depending on the application and the location/operating conditions of HLMs, a number of different significant hazards can arise. This document describes both the areas of hazards analysis and risk assessment as well as protective measures.
Requirements dealing with noise as a hazard are covered by ISO 11553-3:2013.
This document does not apply to laser products or equipment manufactured solely or expressly for applications which are excluded from the Scope of ISO 11553-1:2020. This document is not applicable for HLMs which have been manufactured before the date of publication of this standard.

This document specifies procedures for static and cyclic strength tests on lower-limb prostheses (see NOTE 2) which typically produce compound loadings by the application of a single test force. The compound loads in the test sample relate to the peak values of the components of loading which normally occur at different instants during the stance phase of walking. This document specifies Test Ranges (R) by specifying locomotion profiles for the cyclic test in relation to the intended use. According to the concept of the tests of this document, each sample of lower limb prosthetic device or structure submitted for test is, nevertheless, free to develop its individual performance under load. The tests described in this document comprise: principal static and cyclic tests for all components; a separate static test in torsion for all components; separate static and cyclic tests on ankle-foot devices and foot units for all ankle-foot devices as single components including ankle units or ankle attachments and all foot units as single components; a separate static ultimate strength test in maximum knee flexion on knee joints and associated parts for all knee units or knee-shin-assemblies and adjacent components that normally provide the flexion stop on a complete prosthesis; optional separate tests on knee locks for all mechanisms which lock the knee joint in the extended position of the knee unit or knee-shin-assembly. The tests described in this document apply to specific types of ankle-disarticulation prostheses (see NOTE 2), to transtibial (below-knee), knee-disarticulation and transfemoral (above-knee) prostheses and to the distal (lower) part of hip-disarticulation and hemi-pelvectomy prostheses (see NOTE 3). The test geometry described in this standard is only intended to be used up to a level of 150 mm above the knee-joint centre. This document is suitable for the assessment of the conformity of lower limb prosthetic devices or structures with the strength requirements specified in ISO 22523:2006, 4.4 (see NOTE 1). Lower limb prosthetic devices or structures on the market, which have demonstrated their compliance with the strength requirements specified in ISO 22523:2006, 4.4 through submission to the relevant tests of ISO 22523:2006, need not be retested to this document. NOTE 1 The tests can be performed on complete structures, on part structures or on individual components. NOTE 2 The tests only apply to ankle-disarticulation prostheses which include (foot) components of prosthetic ankle-foot devices taken from the normal production line. NOTE 3 The distal part comprises the knee unit, the ankle-foot device and all parts between. Tests on hip units are described in ISO 15032.

This document gives guidance on the sample preparation of milk and milk products for physical and chemical analysis, including analysis by applying instrumental methods. This document specifies the (sub)sampling and sample preparation steps carried out after sampling in accordance with ISO 707 | IDF 50 [1] and prior to method-specific sample preparations (e.g. as with analytical methods). NOTE Analysis on volatile substances, minor components or allergens can require additional precautionary measures in sample preparation in order to avoid loss of or contamination with one or more target analytes.
