EN 13213-2001 pdf download.Hollow floors.
Drill a hole of diameter 6 mm in the centre of the indentor position into the load-bearing layer. Insert the measurement stick through the hole down to the rigid surface.
Place a rubber plate of 3 mm thickness and 65 shore A hardness in accordance with ISO 48 between indentor and specimen.
Apply the load with a steel indentor in accordance with figure 2.
Apply a steadily increasing load at a rate of 120 N/s ± 10 % until working load is reached. Read the move of the indentor corresponding to the measurement stick as maximum deflection.
5.4 Solidity of load bearing layer
The test procedure and size of the specimen are described in EN 196-1.
The prisms shall be produced with the same material which is used in the hollow floor construction.
These samples shall be tested with regard to the bending strength and compressive strength tested in accordance with EN 196-1.
5.5 Dimensional deviations
5.5.1 ThIckness of the load bearing layer
Control measurements of the thickness of the load bearing layer shall be done at random using a dial gauge with an accuracy of 0,1 mm and noted.
5.5.2 MeasurIng the flatness deviations
Verification of deviations from the flatness shall be done by individual measurement of limit values, e.g. spot check inspection (see figure 3) or by using a grid system to measure the levels. The grid shall be measured out.
6 Evaluation of conformity
6.1 General
The compliance of a hollow floor with the requirements of this standard and with the stated values (including classes) shall be demonstrated by:
– initial type testing
– factory production control by the manufacturer, including product assessment. For the purposes of testing, floors may be grouped into families, where it is considered that the selected property is common to all floors within that family.
NOTE A family is a group of products within which a change of components does not affect the characteristic(s) stated.
6.2 Type testing
6.2.1 Initial type testing
Initial type testing shall be performed on first application of this standard. Tests previously performed in accordance with the provisions of this standard (same product, same characteristic(s) , test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account. Whenever a change occurs in the floor design, the raw material or supplier of components, or the production process ( subject to the definition of a family, see 6.1), which would change significantly one or more of the stated characteristics, the type test shall be repeated for the appropriate characteristic(s).
If tests or assessments (e.g. reaction to fire, release of dangerous substances) have been performed in accordance with the provisions of this or other European standards and are stated with the component or raw material concerned, the manufacturer of the hollow floor need not repeat the test or assessment.
6.3 Factory production control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain a FPCsystem to ensure that the product placed on the market conforms with the stated performance characteristics. The FPCsystem shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product.
A FPC-system conforming with the requirements of the relevant part(s) of EN ISO 9000, and made specific to the requirements of this standard, will be considered to satisfy the above requirements.
The result of inspections, tests or assessments shall be recorded, as shall any action taken. The action to be taken when control values or criteria are not met shall be recorded.
6.3.2 Equipment
All weighing, measuring and testing equipment used by the manufacturer shall be calibrated and regularly inspected according to documented procedures, frequencies and criteria.
6.3.3 Raw materials and components
The specifications of all incoming raw materials and components shall be documented, as shall the inspection scheme for ensuring their conformity.
6.3.4 Design process
If design or calculation has been used, (except where verified by testing), the FPCsystem shall document the design of products, identify the checking procedure and those individuals responsible for the design.
During the design process itself, a record shall be kept of all checks, their results, and any corrective actions taken. The record shall be sufficiently detailed and accurate to demonstrate that all stages of the design phase, and all checks, have been carried out satisfactorily.EN 13213-2001 pdf download.
