“All Glory, Laud and Honour” is a hymn written by Theodulf of Orléans around 820 AD, originally in Latin as “Gloria, laus et honor.” Composed during his imprisonment in Angers, France, it was meant for Palm Sunday, celebrating Jesus’ triumphal entry into Jerusalem.
The hymn became part of liturgical traditions, sung during processions. Translated into English by John Mason Neale in 1854, it gained widespread use in Anglican and other churches. Its enduring melody, often paired with the text, is attributed to Melchior Teschner (1615). The hymn remains a staple in Christian worship, especially during Holy Week.
Primary Standards: NIST maintains primary color standards, such as spectral reflectance and transmittance standards, that are traceable to international measurement systems.
Calibration of Instruments: Instruments used for color measurement are calibrated using these standards to ensure accuracy and consistency.
2. Instrumentation
Spectrophotometers: These instruments measure the intensity of light at different wavelengths. They are used to obtain the spectral reflectance or transmittance of a sample.
Colorimeters: These are simpler instruments that measure color using a few broad wavelength bands. They are often used for less precise applications.
3. Measurement Process
Sample Preparation: The sample to be measured is prepared according to specific protocols to ensure uniformity and consistency.
Spectral Measurement: The spectrophotometer or colorimeter measures the light reflected or transmitted by the sample across the visible spectrum.
Data Collection: The data collected includes the spectral power distribution, which indicates how much light is reflected or transmitted at each wavelength.
4. Data Analysis
Color Spaces and Models: The raw spectral data is converted into color space coordinates (e.g., CIE XYZ, Lab) using mathematical models. These models account for human vision characteristics and provide a numerical representation of color.
Comparison and Reporting: The measured color can be compared to standard references or reported in various formats depending on the application (e.g., color difference ΔE).
5. Quality Control and Assurance
Repeatability and Reproducibility: NIST ensures the repeatability and reproducibility of color measurements by using rigorous quality control protocols.
Uncertainty Analysis: The uncertainty associated with the measurements is analyzed and reported to provide a clear understanding of the precision of the measurements.
Example Instruments and Techniques
Goniospectrophotometers: These measure the color of materials that change appearance with viewing angle.
Integrating Spheres: These are used with spectrophotometers to measure diffuse reflectance or transmittance.
Laser-based Systems: Advanced systems that use lasers for highly precise color measurements.
NIST’s methods are designed to provide highly accurate and reliable color measurements that can be used across a wide range of industries, including manufacturing, textiles, and digital imaging.
Colours determine our lives – consciously and subconsciously. They give us direction, influence our emotions, act as a means of communication, underline individuality and give us our identity. RAL colours have existed in all areas of our lives for decades and they set the colour standards for clear global communication of colour in architecture, design, skilled trades and industry.
Enter into the three RAL colour ranges with over 2,500 clearly specified shades for professional colour design. Find out on our website about our colour collections, our analogue and digital products as well as the latest trends from the world of RAL colours.
NFPA 1 Fire Code does not have a specific section dedicated solely to painting facility safety. However, there are several sections within NFPA 1 that address fire safety requirements relevant to painting facilities. These sections provide guidelines and standards for various aspects of fire prevention and protection. Here are some key sections within NFPA 1 that are relevant to painting facility safety:
Chapter 10: Hazardous Materials: This chapter outlines requirements for the storage, handling, and use of hazardous materials, including paints, solvents, and flammable liquids. It covers topics such as storage limitations, ventilation, spill control, and fire protection measures.
Chapter 13: Spraying, Dipping, and Coating Using Flammable or Combustible Materials: This chapter addresses specific fire safety requirements for spray booths, spray rooms, and dip tanks used in painting and coating operations. It covers aspects such as construction, ventilation, electrical equipment, ignition sources, and fire suppression systems.
Chapter 15: Spraying and Dipping Operations: This chapter provides general requirements for spray finishing operations, including safety precautions, ventilation, electrical equipment, and handling of flammable or combustible materials.
Chapter 16: Combustible Dust-Producing Operations: While not specific to painting, this chapter is important for facilities that generate combustible dust during surface preparation or other operations. It addresses fire and explosion hazards associated with combustible dust, providing requirements for dust control, ventilation, equipment, and other safety measures.
These sections highlight key areas within NFPA 1 that can guide painting facility safety. It is essential to consult the latest edition of NFPA 1 and any applicable local or state fire codes to ensure compliance with the most up-to-date requirements and regulations specific to your location and facility type.

Many people are surprised to learn what counts as a “drink”. The amount of liquid in your glass, can, or bottle does not necessarily match up to how much alcohol is actually in your drink. Even before the United States federal government withdrew from regulating alcohol, the conversation, and degree of agreement and attitude, remains remarkably regionally specific:

We follow the catalog of best practice titles developed by a joint committee of the International Organization for Standardization and the International Electrotechnical Commission that should interest educational institutions with an interest in capturing revenue from students outside their home country (which is nearly every educational organization as far as we can see, save for secondary school districts).
ISO/IEC JTC 1/SC 36 Information technology for learning, education and training is charged with standardization in the field of information technologies for learning, education, and training to support individuals, groups, or organizations, and to enable interoperability and reusability of resources and tool. Excluded from this scope are: •standards or technical reports that define educational standards (competencies), cultural conventions, learning objectives, or specific learning content. Work done by other ISO or IEC TCs, SCs, or WGs with respect to their component, specialty, or domain. Instead, when appropriate, normative or informative references to other standards shall be included. Examples include documents on special topics such as multimedia, web content, cultural adaptation, and security. The landing page for all ISO/IEC JTC 1 is linked below.
We maintain the work products of this committee on the standing agenda of our Global, ICT and Acoustics colloquia. See our CALENDAR for the next online meeting; open to everyone.

The Lion’s Pause, often simply called “The Pause,” is a fond, student-run café and social space located in Buntrock Commons at St. Olaf College in Northfield, Minnesota. Its origins date back to the 1960s when students recognized the need for a dedicated recreational and social hub on campus. The name “Lion’s Pause” reflects the college’s mascot, the lion, symbolizing school pride and community spirit.
Over the decades, The Pause has grown into a multifunctional venue, serving as a café, dining spot, and event space. It offers a range of casual foods like its iconic pizza, snacks, and beverages, all prepared and served by student workers. Beyond dining, The Pause plays a vital role in campus life by hosting concerts, dances, movie nights, open mic events, and other activities, fostering a vibrant and inclusive atmosphere for the St. Olaf community.
