TEMPLATEATLAS R134a Pressure-Temperature Charts | Dimensional Collection PHOTO AND FONT LICENSES Publication date: November 2, 2026 This notice identifies the two third-party photographs and three font families used in the dimensional chart collection. Retain the applicable credits, source links, license notices, and indications of changes when redistributing these assets or charts containing them. The original photographic source files are supplied unchanged in Production/assets. Their chart renditions were prepared as described below. Original dimensional vector illustrations were created for TemplateAtlas and are identified separately from the photographs. A. PHOTOGRAPHS 1. R134a refrigerant cylinder Original file: Production/assets/cylinder.png Original title: R134a container Photographer credited on Commons: Лобачев Владимир (Vladimir Lobachev) License: Creative Commons CC0 1.0 Universal Public Domain Dedication License URL: https://creativecommons.org/publicdomain/zero/1.0/ Source page: https://commons.wikimedia.org/wiki/File:R134a_container.png Original image URL: https://upload.wikimedia.org/wikipedia/commons/4/4b/R134a_container.png Suggested credit: Photo: Vladimir Lobachev / Wikimedia Commons, CC0 1.0. Resized for page placement; grayscale conversion in monochrome editions. The photograph shows a real Coolcraft refrigerant cylinder with a visible 134a label. The original is a 1798 x 3286-pixel PNG with transparency. For PDF placement, it is proportionally resized with Lanczos resampling to fit within 420 x 770 pixels. The RGBA image retains its original alpha transparency. Its transparent background is not flattened onto white. Monochrome editions convert the color channels to grayscale while preserving the alpha channel. Provenance note: the Commons description identifies Vladimir Lobachev and declares the file as own work under CC0. Embedded EXIF metadata names Aleksei Pleshkov. Both records are preserved here to make the source history explicit. 2. Type K thermometer and contact probe Original file: Production/assets/thermometer.jpg Original title: Thermoelement-Thermometer Omega (1) Photographer: Harke Selected license: Creative Commons Attribution-ShareAlike 3.0 Unported License URL: https://creativecommons.org/licenses/by-sa/3.0/ Source page: https://commons.wikimedia.org/wiki/File:Thermoelement-Thermometer_Omega_(1).jpg Original image URL: https://upload.wikimedia.org/wikipedia/commons/3/37/Thermoelement-Thermometer_Omega_%281%29.jpg Suggested credit: Photo: Harke / Wikimedia Commons, CC BY-SA 3.0. Resized and JPEG encoded for page placement; grayscale conversion in monochrome editions. Original photograph supplied with the collection. The photograph shows a real Omega HH501DK Type K thermometer with a contact probe on a white background. The original is 1495 x 2875 pixels. Its PDF rendition is proportionally resized with Lanczos resampling to fit within 1050 x 1050 pixels, converted to RGB, and encoded as optimized JPEG at quality 88 with 4:4:4 color sampling. Monochrome renditions are converted to grayscale before RGB encoding. The depicted equipment has not been redrawn. The original photograph and any adapted photographic versions supplied with this collection are distributed under CC BY-SA 3.0. Preserve the photographer credit, source and license links, and the indication of changes. The Commons page also offers other licenses; this collection selects CC BY-SA 3.0 for this photograph. B. PHOTOGRAPHIC PREPARATION AND ATTRIBUTION The supplied original photographs remain unchanged. Resizing, encoding, and monochrome conversion apply only to renditions prepared for the charts. Page placement preserves the photographs' aspect ratios. The matching WebP pages are lossless renders of the completed PDFs. This lossless page encoding preserves the rendered page; it does not reverse the thermometer photograph's JPEG compression or restore detail removed during image resizing. Visible product names identify the equipment depicted. Use of these photographs does not imply endorsement by their photographers, equipment manufacturers, font authors, or Wikimedia. The TemplateAtlas logo is user-supplied brand artwork and is separate from the third-party photo and font licenses in this notice. C. ORIGINAL VECTOR ARTWORK AND VISUAL RESEARCH The shaded pressure gauge, copper heat-exchanger coil, two-phase vessel, and CF3-CH2F molecular illustration are original vector artwork created for TemplateAtlas. Their shapes, material shading, highlights, and compositions were produced specifically for this collection. Saturation curves are drawn from the canonical R134a numerical model. The gauge needle is calculated from a stated saturation reference and a linear 0-200 psig scale. Phase-vessel volumes and molecular geometry are illustrative rather than quantitative measurements. The method document explains these distinctions. Official manufacturer material was consulted to understand equipment and technical-publication conventions. In particular, the Testo 550s brochure was used for visual research. Its product photographs, branding, and screen readouts were not copied into the collection. The original vector artwork does not imply manufacturer endorsement. Visual research reference: https://static.testo.com/image/upload/US/testo-550s-datasheet-us.pdf D. FONT SOFTWARE AND PRODUCTION INSTANCES All three font families use the SIL Open Font License, Version 1.1. Their supplied copyright notices and complete license texts are included below and in the named files under Production/fonts. The OFL permits font embedding subject to its terms and states that the requirement for font software to remain under the OFL does not apply to documents created using that font software. 1. Manrope Copyright 2018 The Manrope Project Authors Official project: https://github.com/googlefonts/manrope Bundled license: Production/fonts/manrope-OFL.txt Source variable font: Production/fonts/manrope-variable.ttf Production static instances: manrope-500.ttf, manrope-700.ttf, manrope-800.ttf (weight-axis values 500, 700, and 800 respectively). Manrope 800 provides the principal display headings. Manrope 700 is available for labels and supporting display typography. The source variable font was instantiated at the listed weights to create static TrueType files for PDF production. Glyph designs were not redesigned. The supplied copyright notice does not declare a Reserved Font Name. 2. Space Grotesk Copyright 2020 The Space Grotesk Project Authors Official project: https://github.com/floriankarsten/space-grotesk Bundled license: Production/fonts/spacegrotesk-OFL.txt Source variable font: Production/fonts/spacegrotesk-variable.ttf Production static instances: spacegrotesk-400.ttf, spacegrotesk-500.ttf, spacegrotesk-600.ttf, spacegrotesk-700.ttf (weight-axis values 400, 500, 600, and 700 respectively). Space Grotesk provides supporting headings and labels. The source variable font was instantiated at the listed weights for static TrueType PDF use. Glyph designs were not redesigned. The supplied copyright notice does not declare a Reserved Font Name. The Manrope and Space Grotesk instances retain their source family identities and accompanying copyright and OFL notices. Production registration aliases are internal document-generation identifiers. They do not claim authorship of the typeface designs. 3. IBM Plex Copyright © 2017 IBM Corp. with Reserved Font Name "Plex" Official project: https://github.com/IBM/plex Bundled license: Production/fonts/OFL.txt The production font bundle includes IBM Plex Sans (Regular, Text, Medium, SemiBold, and Bold), IBM Plex Sans Condensed SemiBold, IBM Plex Mono Regular, and IBM Plex Serif (Regular and SemiBold). IBM Plex Sans Text and SemiBold provide the main body and numerical table typography; other supplied family members support selected text treatments. These supplied static IBM Plex font files retain their original font software notices. No glyph redesign or family renaming is applied. Selected fonts are embedded in the chart PDFs to preserve their intended appearance. The Reserved Font Name notice remains part of the license. E.
