This part of ISO 8655 specifies a photometric reference measurement procedure for the determinationof volume of piston-operated volumetric apparatus. The tests are applicable to complete systemscomprising the basic apparatus (with a maximum nominal volume of 10 mL) and all parts selected foruse with the apparatus, disposable or reusable, involved in the measurement by uptake (In) or delivery(Ex).NOTE General requirements and definitions of terms for piston-operated volumetric apparatus aregiven in ISO 8655-1. For the metrological requirements, maximum permissible errors, requirements formarking and information to be provided for users for piston-operated volumetric apparatus, see ISO8655-2 for pipettes, see ISO 8655-3 for burettes, see ISO 8655-4 for dilutors, see ISO 8655-5 fordispensers, and see ISO 8655-9 for manually operated precision laboratory syringes. The gravimetricreference measurement procedure for the determination of volume of piston-operated volumetricapparatus is given in ISO 8655-6. Alternative methods for the determination of volume are given in ISO8655-7.

This part of ISO 8655 specifies- metrological requirements,- maximum permissible errors,- requirements for marking and- information to be provided for users,for manually operated precision laboratory syringes. It applies to syringes with nominal volumes up to 200 ml, designed to deliver their volume (Ex).Manually operated precision laboratory syringes are instruments used for delivering liquids and gases.The barrel is typically made of glass and the plunger and the needle are typically made of metal.NOTE General requirements and definitions of terms for piston-operated volumetric apparatus are given in ISO 8655-1. The gravimetric reference measurement procedure for the determination of volume is given in ISO 8655-6. A photometric reference measurement procedure for the determination of is given in ISO 8655-8. Alternative methods for the determination of volume are described in ISO 8655-7.

This European Standard specifies minimum performance and durability requirements for shockpads and elastic layers used within synthetic turf, needle-punch and textile sports surfaces. It applies to any shockpad used as an elastic component in sports surfacing system. The Standard describes how the performance of a shockpad or elastic layer shall be measured, and the results classified in a common format to enable developers of sports surfacing systems that wish to use shockpads or elastic layers to select the most appropriate shockpad or elastic layer for their intended sports surface. It also details the maximum changes in performance a shockpad or elastic layer should experience when subjected to artificial ageing if it is to offer satisfactory long-term performance when installed within a sports surfacing system. The Standard also specifies appropriate performance tolerance for production and on-site quality control procedures. Note1: The sports performance characteristics of a synthetic turf, needle-punch or textile sports surface are provided by the combined characteristics of the playing surface, any infill within the playing surface pile and any shockpad. The selection of the correct permutations of each is complex and the responsibility of the sports surface designer. It is important to take these facts into account when considering the performance of a shockpad; a shockpad alone should not be expected to satisfy the performance requirements of the complete playing surface as specified in EN 15330-1 and EN 15330-2. Note 2: This Standard only refers to the shockpad or elastic layer. It makes no recommendations on sub-base constructions or the different synthetic turf for needle-punch textile sports surface designs. Note 3: Some types of shockpad are also intended to provide structural properties to the base of a sports facility. These aspects of a shockpad’s performance are not considered by this European Standard. Where appropriate compliance with national standards and guidelines for these aspects should be followed.

This document specifies requirements and test methods for manual wheelchairs intended to carry one person of mass not greater than 250 kg, including:— stand-up manual wheelchairs, and— manual wheelchairs for showering and/or toileting.This document does not apply to custom-made manual wheelchairs or manual wheelchairs intended for use in sports.This document also specifies requirements and test methods for manual wheelchairs with electrically powered ancillary equipment.

This series of standards applies to welding of metallic materials in the manufacture and maintenance of railway vehicles and their parts.This part of the series describes the production requirements (i.e. preparation and execution) of the welding work.
