The method describes the quantitative determination of the concentration of in-can free formaldehyde in water-dilutable coating materials. The determination method A for in-can free formaldehyde can be only of limited suitability for pigmented systems, as the inherent coloration of the material may have an influence on the detection.

This part of ISO 16365 establishes a system of designation for thermoplastic polyurethane elastomers, which is based on ISO 1043 (all parts) and ISO 11469. The designation system may be used as the basis for specifications. The designation system is applicable to all thermoplastic polyurethane elastomers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colourants, fillers or other additives, etc. The types of thermoplastic polyurethane are differentiated from each other by a classification system based on appropriate levels of the designatory properties: and on information about the alternating hard and soft segments in the main chain, the intended application and/or method of processing, important properties, additives, colour, fillers, and reinforcing materials. It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 16365 does not provide engineering data, performance data, or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, it is intended that they be determined in accordance with the test methods specified in ISO 16365-2, if suitable. In order to specify a thermoplastic elastomer for a particular application or reproducible processing, additional requirements are intented to be given in data block 5 (see 3.1 and 3.6).

This document specifies two methods of the determination of free formaldehyde (HCHO) in polymer dispersions. This document is applicable to acrylic, acrylonitrile butadiene, carboxylated styrene-butadiene and vinyl acetate polymer dispersions. This document can also be applicable to polymer dispersions of other compositions. Method A (UV/Vis spectrometer method) is applicable to polymer dispersions with a free-formaldehyde content higher than 10 mg/kg. Method B (HPLC method) is applicable when lower formaldehyde contents have to be determined or arbitration analyses have to be carried out.

This document specifies a test method for comparing the compression shear strength of adhesive bonds and solid wood at 180 °C and a second elevated temperature. The maximum load of the test pieces after exposure to 180 °C and a specific elevated temperature for a specified duration of time is evaluated. It is applicable to adhesives used in load bearing timber structures and to other wood adhesives. This method is intended primarily to obtain data for the performance of wood adhesives at high temperatures. The result of this method (temperature class) can be used to classify the adhesive with respect to its performance in fire.
