This International Standard specifies the characteristics of laminate floor coverings, supplied in either tile or plank form. To encourage the consumer to make an informed choice, the standard includes a classification system (see ISO 10874) based on intensity of use, which shows where these floor coverings should give satisfactory service. It also specifies requirements for marking and packaging…
Space systems — Environmental testing for spacecraft thermal control materials
This international standard intends to establish a guideline for the ground-based environmental tests of thermal control materials (TCMs) used on spacecraft’s surface. This standard describes the test methods of charged particle radiation(s), solar ultraviolet (UV), atomic oxygen (AO) and thermal cycling. Typical TCMs include, but are not limited to, coatings, optical solar reflector (OSR) and…
The proposal of this new work item is to develop the standard of "Quick-frozen coated aquatic products". The standard specifies the requirements for quick-frozen coated aquatic products and the test methods for quality control. It also specifies the requirements of packaging, marking, storage and transportation. The standard is applicable to quick-frozen aquatic products-breaded or in…
Non-destructive testing — Ultrasonic testing — Specification for standard block No. 1
This International Standard specifies requirements for the dimensions, material and manufacture of a steel block for calibrating ultrasonic test equipment used in manual testing.
Plastics — Strain rate dependent tensile tests for thermoplastics at ambient temperature
The proposed standard defines the general principles for determining stress-strain curves for plastics 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…
Fans — Laboratory methods of testing air circulating fans
This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans that are larger than 1800 mm, which do not have a lower input power limit. The diameter of the fan being tested shall be limited…
Measurement of radioactivity — Gamma emitting radionuclides — Rapid screening method using scintilla...
ISO 19581 specifies a screening test method to quantify rapidly the activity concentration of gamma-emitting radionuclides, such as 131I, 132Te, 134Cs and 137Cs, in solid or liquid test samples using gamma-ray spectrometry with lower resolution scintillation detectors as compared with the HPGe detectors (see IEC 61563).
This test method can be used for the measurement of any potentially…
Space systems — Liquid rocket engines and test stands — Terms and definitions
ISO 17540:2016 provides terms and definitions in scope of design, testing, reliability analysis and quality control of liquid rocket engines. The terms are required for use in all types of documentation and literature including in the scope of standardization or using the results of this activity.
