Gaseous hydrogen — Pressure vessels for stationary storage — Part 3: Pressure cycle test data to demonstrate partial pressure cycle estimation methods
Käsitlusala: This document describes detailed methods for evaluating cycle life extension by partial pressure cycles with necessary conditions and example data of their application.
Two methods for evaluating cycle life extension by partial pressure cycles based on the Goodman diagram and exponential formula are presented in ISO 19884-1. These methods do not rely on fracture mechanical methodology but on pressurizing cycle test data, since the framework of ISO 19884-1 is constructed on performance demonstrated by pressurizing cycle test data in hydrogen.

Photovoltaic (PV) module performance testing and energy rating - Part 2: Spectral responsivity, incidence angle and nominal module operating temperature measurements
Käsitlusala: IEC 61853-2:2026 establishes IEC requirements for evaluating PV module performance based on power (watts), energy (joule or watthours) and performance ratio. It is written to be applicable to all PV technologies, including bifacial PV modules, but can be unsuitable for any technology where the module performance changes with time (e.g. modules change their behaviour with light or thermal exposure), or which experience significant non-linearities in any of their characteristics used for the modelling.
The purpose of document is to define procedures for measuring the effects of angle of incidence of the irradiance on the output power of the device, to determine the operating temperature of a module for a specific set of ambient and mounting conditions and measure the spectral responsivity of the module.

This document covers class II and class 0 modules, as defined in IEC 61730-1. Class III modules are out of scope. This document provides the requirements for qualification of front- and backsheets to be used in module safety qualification according to IEC 61730-1. Test method descriptions are provided in IEC TS 62788-2, along with additional characterization methods useful for performance or quality assurance.

Olme- ja bürootarbelised elektri- ja elektroonikaseadmed. Väikese tarbitava võimsuse mõõtmine
Käsitlusala: This European Standard specifies methods of measurement of electrical power consumption and the reporting of the results for a range of electrical and electronic household and office equipment, hereafter referred to as products. This standard - addresses issues associated with measuring electrical power, in particular low power (in the order of a few Watts or less), consumed by mains powered products, - describes in detail the requirements for testing single phase products with a rated input voltage in the range of 100 V a.c. to 250 V a.c. but it may, with some adaptations, also be used with three phase products, - may also be of assistance in determining the energy efficiency of products in conjunction with other, more specific, product standards. The value of energy consumed will depend on the operating mode of the product under test, for instance whether the equipment is in an off mode, in a standby mode or in an active mode. This standard does not specify these modes and so it is not possible to use this standard on its own. Instead, it provides a method of measurement with a variety of modes which are defined elsewhere.

In this case, the hose or tubing would not carry any marking showing the number of this document but can detail the OEM's own identification markings as shown on their part drawings.

Fuel cell technologies - Part 2-400: Fuel cell modules - Calculation of rated power and power density of a PEM stack and PEM module
Käsitlusala: This document specifies methods for calculating the rated power and power density of PEM fuel cell stacks and modules.
To supply power to an application, the stack or module shall be integrated within a fuel cell power system, as illustrated in Figure 1 in accordance with IEC 62282-2-100:2020.
This document applies to all PEM fuel cells, irrespective of their application and PEM technology type, including high-temperature PEM fuel cells.
Figure 1 – Fuel cell power system components
Fuel cell modules may be fitted with or without enclosures, and can operate at substantial pressurisation levels or near ambient pressure.
Since peripheral devices affect the net power output of the fuel cell power system, this standard focuses on the stack and module in their standalone state prior to such peripheral influences, as illustrated in Figure 1.
This document excludes the storage and delivery of fuel and oxidant to the fuel cell module.
