    Beskrivelse
    This Standard specifies the requirements and test methods for the inspection in use of Knapsack sprayers of over 3 litres nominal volume carried on the back or shoulder of the operator for applying Plant Protection Products (PPPs) in agriculture and horticulture. It is applicable to lever-operated knapsack sprayers, knapsack compression sprayers and knapsack sprayers driven by an engine or electric motor using hydraulic energy to atomise the spray liquid. The requirements relate mainly to the condition of the sprayer with respect to its potential risk to the operator and the environment and its performance to achieve good application. It does not apply to other portable equipment such as knapsack combustion engine-driven air blast sprayers/mistblowers (see ISO 10988 and ISO 28139), Controlled Droplet Application equipment utilising rotary atomisers, or portable application equipment for spatial application (e.g. foggers).

    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This International Standard recommends the handling, documentation, storage and processing of formalin fixed and paraffin embedded (FFPE) tissue specimens intended for RNA examination during the pre-examination phase before a molecular assay is performed. This International Standard is applicable to molecular in vitro diagnostic examinations including laboratory developed tests performed by medical laboratories and molecular pathology laboratories. It is also intended to be used by laboratory customers, in vitro diagnostics developers and manufacturers, but also pertains institutions and commercial organisations performing biomedical research, biobanks, and regulatory authorities. The formalin fixation and the paraffin embedding process lead to modifications of the RNA molecules, which can impact the validity and reliability of the examination test results. RNA profiles in tissues can change drastically during collection and change differently in different tissue donors' / patients' tissues. Therefore, it is essential to take special measures to minimize the described RNA profile changes and modifications within the tissue for subsequent examination. NOTE – International, national or regional regulations or requirements may also apply to specific topics covered in this International Standard.

DNA integrity in tissues can change before and during formalin fixation, processing and storage. Chemical modifications introduced into DNA during tissue fixation might lead to fragmentation and sequence alterations, changes in the methylation status or even structural changes which can lead to e.g., spurious copy number changes in array-CGH profiles. These modifications of the DNA molecules can impact the validity and reliability of the examination test results. Therefore, it is essential to take special measures to minimize the described modifications for subsequent DNA examination.

    Forslag om nyt arbejdsemne vedtaget
    Komite
    Beskrivelse
    This Standard describes principles and tools to control a manufacturing process in accordance with a GPS specification. It establishes that the result of a GPS specification, consisting of one value, is not sufficient to control a manufacturing process. For this purpose it is necessary to use a set of one or more complementary, independent characteristics that correlate to the manufacturing process parameters. This Standard describes the concept of decomposition of the macro-geometrical part of the GPS specification. It does not cover the micro-geometry, i.e. surface texture. The objective of the decomposition presented in this standard is to define correction values for manufacturing control or to perform a statistical analysis of the process.

    This International Standard recommends the handling, documentation, storage and processing of frozen tissue specimens intended for the examination of extracted proteins during the pre-examination phase before a molecular assay is performed. This International Standard is applicable to molecular in vitro diagnostic examinations including laboratory developed tests performed by medical laboratories. It is also intended to be used by laboratory customers, in vitro diagnostics developers and manufacturers, but also pertains institutions and commercial organisations performing biomedical research, biobanks, and regulatory authorities. Protein profiles and protein-protein interactions in tissues can change drastically before tissue collection (e.g., due to warm ischemia) and after tissue collection (e.g., due to cold ischemia). The changes are caused by e.g., gene induction, gene down regulation, protein degradation. Protein species amounts can change differently in different donors’ / patients’ tissues. The expression of genes can be influenced by the given treatment or intervention (surgery, biopsy), or drugs administered for anaesthesia or even treatment of concomitant disease as well as by the different environmental conditions after the tissue removal from the body. Therefore, it is essential to take special measures to minimize the described protein profile changes and modifications within the tissue for subsequent examination. Tissues that have undergone chemical stabilization pre-treatment before freezing are not covered in this document. In addition this document is not applicable to protein examination by immunohistochemistry.
