Non-destructive testing - Characterization and verification of ultrasonic air-coupled equipment - Part 2: Probes (ISO/DIS 25222-2:2026)

This document specifies the characteristics of probes used for non-destructive air-coupled ultrasonic testing with centre frequencies above 20 kHz, with focusing or without focusing means. This document refers to probes based on the piezoelectric effect. Air-coupled probes based on other physical principles may be characterized according to this guideline if it is judged as appropriate. This document excludes periodic tests for probes. If parameters specified in this document are to be verified during the probe’s lifetime, as agreed upon by the contracting parties, the procedures of verification for these parameters can be selected from those given in this document.

Dentistry - Dental attachments - Measurement of placement and removal forces (ISO/DIS 3843:2026)

This document specifies a test method for measuring the forces needed for the placement and removal of dental attachments (frictional retention elements of ball head-, snap-on, prefabricated telescopic and bar systems used for the attachment, support and stabilization of crowns and bridges, single attachments, removable partial dentures, complete dentures, and other superstructures on dental implant systems (including monopart implants)and, if not other justified, on natural teeth and root post copings). If not otherwise justified, this document can also be used for tests on custom-made or patient matched devices (e.g. laboratory manufactured). This test method is not applicable to retention devices for which normal placement and removal requires any off-axis rotation for the path of least resistance. This test method is not applicable to dental magnetic attachments, these are specified in ISO 13017.

Respiratory protective devices - Gas cylinder valves - Part 4: Excess flow devices

This document specifies the technical requirements and the necessary tests of Excess Flow Device (EFD) for use with respiratory protective devices (RPD), up to 300 bar operating pressure. Devices that only close the flow in the event of a valve break-off do not fall within the scope of this document. NOTE Throughout the breathing apparatus market exists a variety of cylinder valves that can have different ways of connecting to an EFD. The interchangeability of the EFD is only possible in the case of verified combinations of cylinder valve and EFD. The use of unverified combinations is not considered safe.

Adhesives - Test method for cementitious and calciumsulfate-based floor levelling compounds - Determination of bond strength

This document specifies a test method for the determination of bond strength between an underlayment produced with cementitious or calciumsulfate-based floor levelling compounds and a standard substrate. This document applies to cementitious, and calcium sulphate-based floor levelling compounds used for the preparation of subfloors to ensure the suitability of the substrate prior to the installation of floor coverings. By using the floor levelling compound, a homogeneous layer is built up on the load-bearing substrate, to ensure consistent absorbency, evenness and strength.

Petroleum products - Determination of boiling range distribution by gas chromatography method - Part 2: Heavy distillates and residual fuels

This document specifies a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionization detection. The document is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature, and which have a boiling range of at least 100 °C. The document is applicable to materials with initial boiling points (IBP) above 100 °C and final boiling points (FBP) above 750 °C, for example, heavy distillate fuels and residuals. The method is not applicable to bituminous samples. The test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphthas, reformates, gasolines) or middle distillates like Diesel and Jet fuel. Petroleum or petroleum products containing blending components, which contain hetero atoms (for example alcohols, ethers, acids, or esters) or residue, are not to be analysed by this test method. NOTE For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction. WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
