Preparation and quality management of fluids for haemodialysis and related therapies - Part 4: Concentrates for haemodialysis and related therapies (ISO 23500-4:2024)
kSIST FprEN ISO 23500-4:2024

This document specifies the chemical and microbiological requirements for concentrates used for haemodialysis and related therapies and applies to the manufacturer of such concentrates.
This document is applicable to:
—     concentrates in both liquid and powder forms;
—     additives, also called spikes, which are chemicals that can be added to the concentrate to supplement or increase the concentration of one or more of the existing ions in the concentrate and thus in the final dialysis fluid;
—     equipment used to mix acid and bicarbonate powders into concentrate at the user's facility.
This document does not apply to:
—     concentrates prepared from pre-packaged salts and water at a dialysis facility for use in that facility;
—     pre-packaged and sterile dialysis fluid;
—     sorbent dialysis fluid regeneration systems that regenerate and recirculate small volumes of the dialysis fluid;
—     equipment to perform patient treatment; this is addressed IEC 60601-2-16.
This document does not cover the dialysis fluid that is used to clinically dialyse patients. Dialysis fluid is covered in ISO 23500-5. The making of dialysis fluid involves the proportioning of concentrate and water at the bedside or in a central dialysis fluid delivery system. Although the label requirements for dialysis fluid are placed on the labelling of the concentrate, it is the user's responsibility to ensure proper use.

Design of fans working in potentially explosive atmospheres
kSIST FprEN 14986:2024

1.1   This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres.
NOTE 1   Operation conditions for the different categories of fans used in this document are defined in Clause 4.
1.3   This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan.
This document covers mechanical equipment, in particular fans. The “type of protection” as specified in EN ISO 80079 37:2016 is constructional safety.
1.4   This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having
—   absolute pressures ranging from 0,8 bar to 1,1 bar,
—   and temperatures ranging from −20 °C to +60 °C,
—   and maximum volume fraction of 21 % oxygen content,
—   and an aerodynamic energy increase of less than 25 kJ/kg.
NOTE 1   25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3.
This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter.
NOTE 2   Temperatures below −20 °C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of −20 °C to +60 °C the normal ambient temperature range for the equipment is −20 °C to +40 °C unless otherwise specified and marked.
1.5   This document does not apply to:
—   group I fans (fans for mining);
—   explosion group IIC (other than hydrogen);
—   category 1D fans;
—   cooling fans or impellers on rotating electrical machines;
—   cooling fans or impellers on internal combustion engines, vehicles or electric motors.
NOTE 3   Measures for category 1D fans are given in EN 1127 1:2019.
NOTE 4   Measures for explosion group IIC (other than hydrogen) are given in EN 1127 1:2019.
NOTE 5   Measures for explosion group I are given in EN ISO/IEC 80079 38:2016 and EN 1127 2:2014.

Coil coated metals - Test methods - Part 3: Colour difference and metamerism - Instrumental comparison
oSIST prEN 13523-3:2023

This document specifies procedures for determining the instrumental colour difference (CIELAB   or  ) of an organic coating on a metallic substrate compared to another one used as a reference (usually called reference) and the metamerism depending on the illuminant.
When two colour specimens have identical spectral reflectance curves, they are matching under any illuminant irrespective of its spectral characteristics. This is termed a “spectral match”. It is also possible for two colour specimens having different spectral reflectance curves to match visually under a given light source but not to match under another light source with different spectral characteristics; such matches are termed "metameric".
One quantitative description of metamerism is the so-called "metamerism index".
Information on the metamerism index is of limited value where ΔE (instrumental colour difference for a given illuminant) is > 0,5. The metamerism index is not suited for determining the absolute colour difference or colour consistency of a given specimen at change of illuminant.
The colour difference under the reference illuminant is to be measured in colour coordinates L*, a* and b*.
Excluded from this method are organic coatings producing fluorescence and/or which are multicoloured, pearlescent or metallic.
Establishing a reference as well as the magnitude of an acceptable colour difference are not covered by this method.
Two methods are given in this document:
a)   instrumental colour difference measurement using a tristimulus colourimeter;
b)   instrumental colour difference measurement using a spectrophotometer or equivalent.
It is advised that care is taken when measuring e.g.
-   textured surfaces;
-   fluorescent coatings;
-   metameric coatings;
-   multi-coloured, pearlescent, metallic or special colour effect coatings.

kSIST FprEN ISO 23500-5:2024

This document specifies the minimum chemical and microbiological quality requirements for dialysis fluids used in haemodialysis and related therapies.
This document applies to
—     dialysis fluids used for haemodialysis and haemodiafiltration,
—     substitution fluid produced online for haemodiafiltration and haemofiltration based on dialysis fluid
This document does not apply to
—     the water and concentrates used to prepare dialysis fluid or the equipment to produce dialysis fluid
—     sorbent-based dialysis fluid regeneration systems that regenerate and recirculate small volumes of dialysis fluid,
—     systems for continuous renal replacement therapy that use pre-packaged solutions, and
—     systems and solutions for peritoneal dialysis.
The delivery and monitoring of the dialysis fluid composition and its permitted deviation from set points is governed by protective systems defined in IEC 60601-2-16.

Coil coated metals - Test methods - Part 22: Colour difference - Visual comparison
oSIST prEN 13523-22:2023

This document specifies the procedure for determining the difference in the colour of an organic coating on a metallic substrate by visual comparison against a standard using either diffuse natural daylight or artificial daylight in a standard booth.
NOTE   Results can differ between natural and artificial daylight.
It might be that two colour specimens will match in daylight but not under another light source. This phenomenon is known as metamerism (see EN 13523 3).
If a metameric match is to be reported in objective terms, spectrophotometric measurements (using CIE Standard Illuminants D65 and A) can be made, in accordance with EN 13523 3.
No statement is made about either the precision or the accuracy of this procedure since the results derived are neither in numerical form nor do they provide a pass/fail evaluation in objective terms. Therefore, this procedure is only intended to be used where the use of colour measuring instruments is not recommendable (evaluation of colour matches, inspection of metallic colours, etc.).
The standardization of such visual comparisons, by light sources, illuminating and viewing geometry and specimen size, provides for improved uniformity of results. This practice is essential for critical colour matching and is highly recommended for colour inspections.
