Plastics - Ultra-high-molecular-weight polyethylene (PE-UHMW) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO/DIS 21304-2:2026)

This document specifies the methods of preparation of test specimens and the test methods to be used for determining the properties of ultra-high-molecular-weight polyethylene (PE-UHMW) moulding and extrusion materials. It establishes general principles for handling test materials and for conditioning both the test materials before moulding and the specimens before testing. This document specifies procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made. Properties and test methods which are suitable and necessary to characterize PE-UHMW moulding and extrusion materials are established. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 21304-1. This document specifies the-materials with MFR less than 0,1 g/10 min at 190 °C /21,6 kg based on ISO 17855-1. The methods of preparation and conditioning, the specimen dimensions and the test procedures specified in this document are used in order to obtain reproducible and comparable test results. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

Methods of testing cement - Part 5: Pozzolanicity test for pozzolanic cement

In this document, the pozzolanicity of a cement is assessed by comparing the concentration of calcium ion, expressed as calcium oxide, present in the aqueous solution in contact with the hydrated cement, after a fixed period of time, with the quantity of calcium ion capable of saturating a solution of the same alkalinity.

Agricultural and forestry machinery - Environmental requirements for sprayers - Part 4: Fixed and semi-mobile sprayers (ISO/DIS 16119-4:2026)

This part of ISO 16119 specifies requirements and the means for their verification for the design and performance of fixed and semi-mobile sprayers, as defined in 3.1 and 3.2, with regard to minimizing the potential risk of environmental contamination during use, including misuse foreseeable by the manufacturer. This type of spraying system is generally a combination of separate elements (main tank, pump and application unit) that can be assembled in fixed installations (fixed sprayers) or with moving parts (semi-mobile sprayers). It does not apply to application equipment for space/spatial treatments. It is intended to be used with ISO 16119 1, which gives general requirements common to all the sprayer types covered by ISO 16119. When requirements of this part of ISO 16119 are different from those stated in ISO 16119 1, the requirements of this part of ISO 16119 take precedence over the requirements of ISO 16119 1 for machines within the scope of this part of ISO 16119. This part of ISO 16119 does not cover safety aspects (see ISO 4254 6). • Filling - Total tank extra volume • Quick coupler for CTS + mandatory provision of inductor hopper or CTS • Filters drain valve • Digital level indicator + accuracy • Pump requirements as per ISO 12908: 2020 • Residue concentration only one method for system rinsing
