Determination of sustained combustibility of liquids (ISO 9038:2025)
EN ISO 9038:2025

This document specifies a procedure, at temperatures up to 100 °C, to determine whether a liquid product, that would be classified as “flammable” by virtue of its flash point, sustains combustion at the temperature(s) specified, for example, in regulations.
NOTE            Many national and international regulations classify liquids as presenting a flammable hazard based on their flash point, as determined by a recognized method. Some of these regulations allow a derogation if the substance cannot “sustain combustion” at some specified temperature(s).
The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents, petroleum or related products and adhesives, that have a flash point. It is not applicable to painted surfaces in respect of assessing their potential fire hazards.
This test method is applicable, in addition to test methods for flash point, for assessing the fire hazard of a product.

1.1   This draft European Standard deals with safety requirements for construction, manufacturing, installation, maintenance and dismantling of electrically powered vertical lifting platforms affixed to a building structure intended for use by persons with impaired mobility:
-   travelling vertically between predefined levels along a guided path whose inclination to the vertical does not exceed 15°;
-   intended for use by persons with or without a wheelchair;
-   supported or sustained by rack and pinion, rope traction drive, noncircular elastomeric-coated steel suspension members (hereafter called flat belt) traction drive, rope positive drive, chains, toothed belts, screw and nut, guided chain, scissors mechanism or hydraulic jack (direct or indirect);
-   with enclosed liftways;
-   with a speed not greater than 0,15 m/s;
-   with platforms where the carrier is not completely enclosed.
1.2   This draft European Standard deals with all significant hazards relevant to lifting platforms, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4).
1.3   This draft European Standard does not specify the additional requirements for:
-   operation in severe conditions (e.g. extreme climates, strong magnetic fields);
-   lightning protection;
-   operation subject to special rules (e.g. potentially explosive atmospheres);
-   handling of materials, the nature of which could lead to dangerous situations;
-   vertical lifting platforms whose primary function is the transportation of goods;
-   vertical lifting platforms whose carriers are completely enclosed;
-   vertical lifting platforms prone to vandalism;
-   hazards occurring during manufacture;
-   earthquakes, flooding;
-   firefighting, evacuation and behaviour during a fire;
-   noise and vibrations;
-   the design of concrete, hard core, timber or other foundation or building arrangement;
-   the design of anchorage bolts to the supporting structure;

Aerospace series - Industrialization - Guidelines for establishing the manufacturing and inspection file and the associated justifications
EN 9212:2025

The aim of a MIF and the associated justifications is to ensure that manufacturing and/or inspection operations are realized in a compliant and reproducible manner.
The purpose of this document is to provide a guide to the elaboration of the MIF and the associated justifications by:
—   positioning them within the framework:
o   of a programme and its objectives, on the one hand;
o   of the realization of a product, on the other;
—   describing, until production of the product ceases:
o   the principles and conditions applying to the elaboration and then the validation of the MIF within the framework of the industrialization process;
o   the principles and conditions applying to the elaboration and then the validation of the MIJF associated with the MIF, within the framework of the industrialization process;
o   the principles and change and control conditions applying to the MIF and the MIJF.
This document can be used for all processes or sets of processes implemented on a tangible product, which may incorporate software associated with the product. It does not apply to purely software product, commercial-off-the-shelf product (catalogue part) or service (intangible product).
This document applies more particularly to serial production. Nevertheless, the principles and conditions set forth in this document may be applied, making any necessary adaptations, to unit production or to the realization of products to meet development needs (prototypes, demonstrators, etc.).
This document covers the MIF and the MIJF of a product, including the activities related to procurement and the associated industrial means in particular.
