Plastics - Simple heat release test using a conical radiant heater and a thermopile detector (ISO 13927:2015)
SIST EN ISO 13927:2015

ISO 13927:2015 specifies a method suitable for the production control or product development purposes for assessing the heat release rate of essentially flat products exposed in the horizontal orientation to controlled levels of radiant heating with an external igniter. The heat release rate is determined by the use of a thermopile instead of the more accurate oxygen consumption techniques. The time to ignition (sustained flaming) is also measured in this test. Test specimen mass loss can also be measured optionally.

Measurement method of anti-biofilm activity on plastic and other non-porous surfaces

This document specifies a test method to evaluate the anti-biofilm activity of anti-biofilm treated plastics and other non-porous surfaces of products, including intermediate products. It is applicable to products such as plastics, coating materials, ceramics, stainless steels and rubber. Textile and photocatalytic materials are out of its scope. This method is intended to be a screening test for material development, and it is not expected to reflect effects observed in the actual environment in which materials will be deployed. A “Crystal violet staining – Absorbance measurement assay” is used to quantify the amount of biofilm formation in this document.

Plastics - Determination of Charpy impact properties - Part 1: Non-instrumented impact test (ISO 179-1:2023)
EN ISO 179-1:2023

ISO 179-1:2010 specifies a method for determining the Charpy impact strength of plastics under defined conditions. A number of different types of specimen and test configurations are defined. Different test parameters are specified according to the type of material, the type of test specimen and the type of notch.
The method can be used to investigate the behaviour of specified types of specimen under the impact conditions defined and for estimating the brittleness or toughness of specimens within the limitations inherent in the test conditions. It can also be used for the determination of comparative data from similar types of material.
The method has a greater range of applicability than that given in ISO 180 (Izod impact testing) and is more suitable for the testing of materials showing interlaminar shear fracture or of materials exhibiting surface effects due to environmental factors.
The method is suitable for use with the following range of materials:
rigid thermoplastic moulding and extrusion materials (including filled and reinforced compounds in addition to unfilled types) and rigid thermoplastics sheets;
rigid thermosetting moulding materials (including filled and reinforced compounds) and rigid thermosetting sheets (including laminates);
fibre-reinforced thermosetting and thermoplastic composites incorporating unidirectional or multi-directional reinforcements (such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings and milled fibres) or incorporating sheets made from pre-impregnated materials (prepregs), including filled compounds;
thermotropic liquid-crystal polymers.

1.1 This document specifies a method for determining the Izod impact strength of plastics under defined conditions. A number of different types of specimen and test configurations are defined. Different test parameters are specified according to the type of material, the type of test specimen and the type of notch.
1.2 The method is used to investigate the behaviour of specified types of specimen under the impact conditions defined and for estimating the brittleness or toughness of specimens within the limitations inherent in the test conditions.
1.3 The method is suitable for use with the following range of materials:
— rigid thermoplastic moulding and extrusion materials, including filled and reinforced compounds in addition to unfilled types; rigid thermoplastics sheets;
— rigid thermosetting moulding materials, including filled and reinforced compounds; rigid thermosetting sheets, including laminates;
— fibre-reinforced thermosetting and thermoplastic composites incorporating unidirectional or non-unidirectional reinforcements such as mat, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings and milled fibres and sheet made from pre-impregnated materials (prepregs);
— thermotropic liquid-crystal polymers.
1.4 The method is not normally suitable for use with rigid cellular materials and sandwich structures containing cellular material. Notched specimens are also not normally used for long-fibre-reinforced composites or thermotropic liquid-crystal polymers.
1.5 The method is suited to the use of specimens which can be either moulded to the chosen dimensions, machined from the central portion of a standard multipurpose test specimen (see ISO 20753) or machined from finished or semi-finished products such as mouldings, laminates and extruded or cast sheet.
1.6 The method specifies preferred dimensions for the test specimen. Tests which are carried out on specimens of different dimensions or with different notches, or specimens which are prepared under different conditions, may produce results which are not comparable. Other factors, such as the energy capacity of the apparatus, its impact velocity and the conditioning of the specimens can also influence the results. Consequently, when comparative data are required, these factors are to be carefully controlled and recorded.
1.7 The method is not intended to be used as a source of data for design calculations. Information on the typical behaviour of a material can be obtained, however, by testing at different temperatures, by varying the notch radius and/or the thickness and by testing specimens prepared under different conditions.

Plastics - Determination of puncture impact behaviour of rigid plastics - Part 2: Instrumented impact testing (ISO 6603-2:2023)
EN ISO 6603-2:2023

This document specifies a test method for the determination of puncture impact properties of rigid plastics, in the form of flat specimens, using instruments for measuring force and deflection. It is applicable if a force-deflection or force-time diagram, recorded at nominal constant striker velocity, is necessary for detailed characterization of the impact behaviour.
The test method is applicable to specimens with a thickness between 1 mm to 4 mm.
The method is suitable for use with the following types of material:
—    rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds and sheets;
—    rigid thermosetting moulding and extrusion materials, including filled and reinforced compounds, sheets and laminates;
—    fibre-reinforced thermoset and thermoplastic composites incorporating unidirectional or multi-directional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings, milled fibres and sheets made from pre-impregnated materials (prepregs).
The method is also applicable to specimens which are either moulded or machined from finished products, laminates and extruded or cast sheet.
The test results are comparable only if the conditions of preparation of the specimens, their dimensions and surfaces as well as the test conditions are the same. In particular, results determined on specimens of different thickness cannot be compared with one another (see Annex E). Comprehensive evaluation of the reaction to impact stress can be obtained by determinations made as a function of impact velocity and temperature for different material variables, such as crystallinity and moisture content.
The impact behaviour of finished products cannot be predicted directly from this test, but specimens may be taken from finished products (see above) for tests by this method.
Test data developed by this method is not intended to be used for design calculations. However, information on the typical behaviour of the material can be obtained by testing at different temperatures and impact velocities (see Annex D) by varying the thickness (see Annex E) and by testing specimens prepared under different conditions.
It is not the purpose of this document to give an interpretation of the mechanism occurring on every particular point of the force-deflection diagram. These interpretations are a task for scientific research.

The lowest significant frequency is used for the validation. This validation procedure only applies to force measurement systems used in high-speed tensile testing machines showing a level of resonance influence that could be critical to the obtained result. Once the relevant frequencies of the system and the anticipated strain for the given material are known, this method allows to calculate the theoretical maximum allowed test speed too.

EN ISO/ASTM 52936-1:2023

This document specifies the general principles to be followed when test specimens of thermoplastic materials are prepared by laser-based powder bed fusion, which is also called laser sintering. The laser-sintering process is used to prepare specimens layer upon layer in which thermal energy selectively fuses regions of a powder bed. This document provides a basis for establishing reproducible sintering conditions. Its purpose is to promote uniformity in describing the main process parameters, build orientation of the sintering process and also to establish uniform practice in reporting sintering conditions.
The particular conditions required for reproducible preparation of test specimens which will give comparable results will vary for each material used. These conditions shall be agreed upon between the interested parties.

Plastics - Determination of thermal conductivity and thermal diffusivity - Part 2: Transient plane heat source (hot disc) method (ISO 22007-2:2022)
SIST EN ISO 22007-2:2022

This document specifies a method for the determination of the thermal conductivity and thermal diffusivity, and hence the specific heat capacity per unit volume of plastics. The experimental arrangement can be designed to match different specimen sizes. Measurements can be made in gaseous and vacuum environments at a range of temperatures and pressures.
This method gives guidelines for testing homogeneous and isotropic materials, as well as anisotropic materials with a uniaxial structure. The homogeneity of the material extends throughout the specimen and no thermal barriers (except those next to the probe) are present within a range defined by the probing depth(s) (see 3.1).
The method is suitable for materials having values of thermal conductivity, λ, in the approximate range 0,010 W∙m−1∙K−1 < λ < 500 W∙m−1∙K−1, values of thermal diffusivity, α, in the range 5 × 10−8 m2∙s−1 < α < 10−4 m2∙s−1, and for temperatures, T, in the approximate range 50 K < T < 1 000 K.
NOTE 1   The specific heat capacity per unit volume, C, C = ρ ∙ cp, where ρ is the density and cp is the specific heat per unit mass and at constant pressure, can be obtained by dividing the thermal conductivity, λ, by the thermal diffusivity, α, i.e. C = λ/α, and is in the approximate range 0,005 MJ∙m−3∙K−1 < C < 5 MJ∙m−3∙K−1. It is also referred to as the volumetric heat capacity.
NOTE 2   If the intention is to determine the thermal resistance or the apparent thermal conductivity in the through-thickness direction of an inhomogeneous product (for instance a fabricated panel) or an inhomogeneous slab of a material, reference is made to ISO 8301, ISO 8302 and ISO 472.
The thermal-transport properties of liquids can also be determined, provided care is taken to minimize thermal convection.

The essential work of fracture (EWF) method is based on the use of double edge notched tensile (DENT) specimens. 1.2 The method is suitable for use with films or thin sheets, of thickness not greater than 1 mm, made of ductile polymeric materials, in which fracture propagation is stable (crack growth is always driven by the external applied force). If, at any time during the test, brittle fracture occurs, with fast crack propagation driven by the elastic energy stored in the specimen, the sample is not suitable for the application of the present test method.
