analysis at a centralised production and distribution facility As a general rule, the product quality o f a plant is consistent regardless o f the size o f its production system, as long as the feedstock and the operating conditions are consistent I f there are no changes in the feedstock and the operating conditions over a long period o f time, only one quality analysis is needed per operation period The principle o f quality control is to per form a daily analysis Types o f analysis, in order to ease the analytical burden o f hydrogen stations and, at the same time, maintain full quality control However, when the feedstock and the operating conditions have not changed and i f it can be assured that the possibility o f contamination is eliminated by the good operation and control o f the distribution facility by, for example, continuously monitoring the canary species be fore shipping, the test frequency may be reduced to as low as once per year Where the hydrogen generators (such as re formers, water electrolysis apparatus or other processes) on the supply side o f a distribution facility are operated intermittently and i f it can be assured that the possibility o f contamination is eliminated by the good operation and control o f the distribution facility by, for example, continuously monitoring the canary species following the start o f the hydrogen generators, the frequency o f analysis may be reduced to as low as once per year In this document, the good operation and control means not only that the facility has a continuous analytical instrument installed but also that such analytical equipment is calibrated and otherwise properly maintained to produce appropriate results at all times While sampling is to be, as a rule, conducted on the distribution side (transfer side), a separate sampling line may be used as long as it does not raise any quality control issues C.6.4 Routine analysis at a hydrogen station C.6.4.1 Hydrogen stations with off-site supply Hydrogen received by an o ff-site hydrogen station is subject to a routine analysis for the constituents that have not been covered by the centralized hydrogen production and distribution facility and for those that may contaminate the gas a fter it is accepted by the station For individual contaminant species that may enter a fter station acceptance, the frequency o f analysis may be reduced to as low as once per year, provided that the possibility o f contamination is deemed eliminated by having a good operation and control program at the station, such as a purge procedure While sampling is to be, as a rule, made at the end o f a nozzle, it may be conducted upstream o f the uelling nozzle to the extent that no changes occur to the quality o f hydrogen f C.6.4.2 Hydrogen stations with on-site supply When a hydrogen generator (such as re former, water electrolysis apparatus or other processes) is operated in the daily start and shut mode (DSS), the quality o f the hydrogen gas produced fluctuates on a daily basis according to the principle described in C.6.3.1 Such operation therefore calls for one analysis per day As in the case o f the centralized production and distribution facilities in C.6.3.1, the frequency o f analysis may be reduced to as low as once per year, provided that the possibility o f contamination is deemed eliminated by the good operation and control o f the station, such as when accumulators are filled a fter the canary species is continuously monitored for quality control on a daily basis following the start-up the generator In this document, the good operation and control means not only that the facility has a continuous analytical instrument installed but also that such analytical equipment is calibrated and otherwise properly maintained to produce appropriate results at all times The analysis and monitoring o f specific canary species for each hydrogen generator is to be conducted in the same manner as described in C.6.3.1 While sampling is to be, as a rule, made at the end o f a nozzle, it may be conducted upstream o f the uelling nozzle to the extent that no changes occur to the quality o f hydrogen f 108 © ISO 2016 – All rights reserved ISO/TS 19880-1:2016(E) C.6.5 Conditions for conducting non-routine analysis I rre s p e c tive o f whe ther cond ition s e xi s t for conduc

characterizes typical operation o f a vehicle pressure vessel, container, or system For compressed hydrogen gas containers, NWP is the vehicle vessel pressure, as specified by the manu facturer, at a uni form gas temperature o f 15 °C and 100% SOC Equivalent to Working Pressure (WP) as defined in ISO 10286 The MOP is the highest gauge pressure of a component or starts, stops, and transients (e.g 1,25 x NWP) This also 70 MPa system that is expected during normal operation including coincides with the NWP CHSS pressure at 85 °C Equivalent to Developed Pressure (DP) as defined in ISO 10286 87,5 MPa Equivalent to Maximum Working pressure in ISO 17268 The MAWP is the maximum gauge pressure of the working fluid (gas or liquid) to which a piece o f process equipment or system is rated with consideration for initiating fault management above normal operation (e.g the vehicle CHSS 96,6 MPa MAWP = 1,1 x 1,25 = 1,38 x NWP) 1st Level (normal control process): terminate fuelling when target pressure (for example from SAE J2601 tables) is reached This is software controlled 2nd Level (principal fault management: redundant electronic protection level): terminate fuelling when 125 % NWP

(informative) Examples of vehicular impact protection measures E.1 General recommendations Recommendations for the protection o f above ground fuel systems equipment Site layouts should be completed such that the need for physical impact barriers is eliminated or minimized Above ground components located near high speed roads with low angle of impact or with low speed roads with high angle o f impact require installation o f road restraint systems that forms to EN 1317 These are engineered guard rail or crash cushion type systems designed to absorb much o f the energy from the impact, reducing the amount o f vehicle damage that would occur otherwise Rigid barriers are required and solutions are provided where high speed and high vehicle impact is anticipated or there is not su fficient spacing for a guard rail type o f system that requires adequate spacing for deflection o f rail during impact For low speed impact potential from on-site tra ffic a range o f bollard type solutions are available There are two types o f solutions application dependant potential impact speed and vehicle size A Type I bollard (150 mm diameter) to protect equipment from impact by a standard size vehicle and a Type II bollard (200 mm diameter) to protect equipment from impact by a larger vehicle Alternative solutions may be employed which are not noted in this standard The rating o f the impact protection should be validated that the system is engineered to meet the applicable impact forces provided in this document The Designer responsible for site layout and the selection o f the impact protection should take into account other considerations not addressed by this standard to reduce risk o f impact o f equipment to as low as reasonably practicable Tra ffic calming measures such as speed bumps and high containment kerbing and similar should be considered where necessary E D i s p e n s e r s p e c i f i c r e c o m m e n d a t i o n s Dispensers should be located on a concrete island or plinth at least 120 mm above grade, (and for example suspended from a structure where the dispenser is at least 4,25 m above the fuelling pad,) or protected using other appropriate means If the dispensers are located on a concrete island or plinth, the distance from the edge of the raised island to each side of the dispenser should be 200 mm minimum An example o f measures that can be used for preventing a vehicle from accidentally colliding into a dispenser in a hydrogen fuelling station, based on requirements in Japan (a translated summary is provided by ENAA Engineering Advancement Association (ENAA) here due to the document not being available in English): a) A protective fence installed on the side of the dispenser on which a vehicle parks for fuelling: 1) The protective fence should be at least 800 mm in height, made of piping of at least 60 mm in diameter, and buried at least 300 mm underground Its width should be greater than the width of the dispenser © ISO 2016 – All rights reserved 113 ISO/TS 9880-1 : 01 6(E) 2) T he pro te c tive fence shou ld b e s enough to with s ta nd an i mp ac t c au s e d by a p a s s enger vehicle (2t) travelling at 20 km/h; b) Installation of the dispenser on a raised island with a minimum height of 150 mm, and with a f f f f the protective fence; c) A fuelling nozzle suspended from a structure where the dispenser is at least 4,25 m above the fuelling pad; d) A collision sensor (if a seismoscope is to be used instead, one that is capable of detecting vehicle collision) installed at each dispenser to detect vehicle collision Measures should be taken to sound collision The example measures 1) and 2) above are demonstrated in example in Figure E.1 below The structural foundation of the dispenser and the fuelling area should be adequate to support all components including vehicles to be fuelled d i s ta nce o at le as t 0 m m rom the d i s p en s er to the s ide o the pl at orm th at
