Rigid cellular plastics — Determination of compressive properties
This document specifies methods for determining the compressive strength and corresponding relative deformation, the compressive stress at 10 % relative deformation, and the compressive modulus of rigid cellular plastics.
Steel structures — Structural bolting — Test method to determine parameters of bolt tightening proce...
This test method is to be used only if no rules and parameters for tightening exist, e.g. for pretensioning of stainless steel bolting assemblies, or when bolts are pretensioned by turning the head.
This test method establishes a bolt tightening qualification procedure (BTQP) which provides design and execution rules for pretensioning of stainless steel and carbon steel bolting assemblies with…
Rubber hoses and hose assemblies for aircraft ground fuelling and defuelling — Specification
ISO 1825:2017 specifies the dimensions and construction of, and requirements for, four types of hose and hose assembly for use in all operations associated with the ground fuelling and defuelling of aircraft.
All four types are designed for:
a) use with petroleum fuels having an aromatic-hydrocarbon content not exceeding 30 % by volume;
b) operation within the temperature range of −30 °C to +65 °…
Health informatics — Public key infrastructure — Part 4: Digital signatures for healthcare documents
This document supports interchangeability of digital signatures and the prevention of incorrect or illegal digital signatures by providing minimum requirements and formats for generating and verifying digital signatures and related certificates.
This document describes the common technical, operational, and policy requirements that need to be addressed to enable digital certificates to be used in…
Calibration and quality control in the use of radionuclide calibrators
This International Standard specifies the techniques for calibration and usage of pressurised, well-type ionisation chambers for the assay of radionuclides. Such instruments are used to determine the activity, expressed in becquerel (Bq), of photon and some medium to high-energy beta emitting radionuclides.
This document provides the methods and tests for establishing and maintaining acceptable…
Washer-disinfectors — Part 6: Requirements and tests for washer-disinfectors employing thermal disin...
ISO 15883-6:2011 specifies particular requirements for washer-disinfectors (WDs) intended for use when the level of assurance of disinfection that is necessary can be achieved by cleaning and thermal disinfection (A0 not less than 60) and does not require an independent automated record of critical processes to be kept. It is intended to be used in conjunction with ISO 15883-1, which gives…
Durum wheat semolina and alimentary pasta — Estimation of cooking quality of alimentary pasta by sen...
ISO 7304-1:2016 sets out a method for estimation by sensory analysis of the cooking quality of alimentary pasta. Estimation takes place through the evaluation of the following:
- firmness, by chewing;
- liveliness, by manual handling;
- starch release, by manual handling.
The method does not express a preference and only gives an estimate relating to the evaluation of the cooking of the pasta; it…
Plastics — Film and sheeting — Determination of gas-transmission rate — Part 2: Equal-pressure metho...
ISO 15105-2:2003 specifies a method for the determination of the gas-transmission rate of any plastic material in the form of film, sheeting, laminate, co-extruded material or flexible plastic-coated material.
Specific examples, currently in use, of the method are described in the annexes.
