ISO 13802:2015 specifies frequency and methods for the verification of pendulum impact-testing machines used for the Charpy impact test, Izod impact test, and tensile impact test described in ISO 179-1, ISO 180, and ISO 8256, respectively. Verification of instrumented impact machines is covered insofar as the geometrical and physical properties of instrumented machines are identical to non instrumented machines. The force/work verification of instrumented machines is not covered in this International Standard.

This document establishes the terms, definitions, methodologies, and calculations that are necessary for the recovery of waste from plastic products and materials labelled as industrially compostable (hereafter referred to as compostable plastic waste) through organic recycling. The document identifies the different types of organic recycling technologies used in the recovery and subsequent recycling of industrially compostable plastics waste arising from pre-consumer and post-consumer sources. This document also establishes the requirements and calculations to be considered in evaluating organic recycling inputs and outputs and determining output classifications for the recycling operation and the downstream integration points. The document also outlines general quality requirements to be applied in all steps of the recovery process, and provides general recommendations for inclusion in material standards, test standards and product specifications. The process stages, requirements, recommendations, and terminology presented in this document are intended to be of general applicability. This document does not establish test methods and criteria for the definition of the organic recyclability (e.g. compostability) of plastic materials and products. This document refers to plastic waste deriving from products that have been classified as suitable for recovery through organic recycling by the relevant reference standards (e.g., ISO 17088, ISO 18606) and therefore labelled as industrially compostable. These products are generally called “industrially compostable” (e.g. compostable bag, compostable tableware) meaning “suitable for organic recycling”, independently of the final treatment technology (whether it is true aerobic composting, or a combination of anaerobic digestion and composting, or only anaerobic digestion). This document does not address home composting because this gardening practice cannot be classified as recycling.

This document defines sampling conventions for airborne particle size fractions for use in assessing the health relevant exposure from inhalation of particles in the workplace. Conventions are defined for the inhalable, thoracic and respirable fractions. The sampling conventions only describe the inhalation of particles and their penetration in the respiratory tract as governed by inertia (impaction). Deposition in the respiratory tract by other mechanisms, e.g. diffusion, is not considered in this document. The sampling conventions defined in this document apply to both indoor and outdoor workplaces. The assumptions on which the sampling conventions are defined are given in Clause 6. The convention chosen for a specific application will depend on the region of the health effect of the component of interest in the airborne particles (see Clause 5). The conventions can be used with whatever metric is of interest, including particle count, length, surface area, volume or mass. The metric depends on the kind of particle analysis carried out on the sampled aerosol fraction. The health-related fraction concentrations defined in this document are often expressed in mass of the sampled particles per volume of sampled air in order to compare with mass-based occupational exposure limit values. The conventions are not applicable in association with limit values expressed in a different metric, e.g. for fibre limit values defined in terms of the length and diameter of airborne fibres and the ratio of the two (aspect ratio), unless a measurement procedure explicitly requires that a specific health related size fraction is to be sampled/collected [13]. The main purpose of this document is to provide agreement on the particle size fractions to sample and their definitions. Sampling is generally carried out using dedicated samplers, for which there is no need to measure the aerodynamic size distribution of the airborne particles to be sampled. Samplers including a separation into one or more relevant sampling conventions(s) are currently available. In general, no assumptions or pre-knowledge are needed on the number of modes, modal diameter(s) or width of the particle aerodynamic size distribution of the airborne particles to be sampled. Because there is a wide variation from one person to another in the probability of particle inhalation, deposition, reaction to deposition and clearance, this document is not applicable for determining the deposited dose taken up by an individual worker. The conventions are primarily intended for determining workers’ exposure to airborne particles by sampling the airborne particles. This document is not applicable to large particles emitted at high speed that are travelling under the momentum from their emission, instead of being carried by the air (airborne) and aspirated into humans and aerosol samplers by their suction (see Annex B).

ISO 5659-2:2017 specifies a method of measuring smoke production from the exposed surface of specimens of materials or composites. It is applicable to specimens that have an essentially flat surface and do not exceed 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics. It is intended that the values of optical density determined by this test be taken as specific to the specimen or assembly material in the form and thickness tested and are not to be considered inherent, fundamental properties. The test is intended primarily for use in research and development and fire safety engineering in buildings, trains, ships, etc. and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that can be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions. This test procedure excludes the effect of irritants on the eye.

This test procedure excludes the effect of irritants on the eye. It is emphasized that smoke production from a material varies according to the irradiance level to which the specimen is exposed. The results yielded from the method specified in this document are based on exposure to the specific irradiance levels of 25 kW/m2 and 50 kW/m2.

This ISO standard defines the general principles for determining stress-strain curves for thermoplastics in a wide strain rate field, with a focus on data entry of material cards for finite element simulations in the event of transient loads (impact/crash). The procedure is to be used to investigate the strain rate dependent uniaxial tensile deformation behaviour of test specimens and to determine the tensile stress-strain relationship under noncyclic, highly dynamic conditions. The procedure is particularly suitable for use in the material group of injection-moulded thermoplastics, unfilled and filled, including short and long fiber reinforced thermoplastics with a fiber length of up to 10 mm. The proposed standard only describes tests in a standard atmosphere.

This document specifies test methods for the determination of the percentage of defective particles and of the microstructure of metallic blast-cleaning abrasives. This is one of a number of parts of ISO 11125 dealing with the sampling and testing of metallic abrasives for blast-cleaning. The types of metallic abrasive and requirements on each are contained in the various parts of ISO 11124. The ISO 11124 and ISO 11125 series have been drafted as a coherent set of International Standards on metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.
