Multi-user, multi-platform, open-source, completely free.

Simply choose a unique group name (with optional password), and instantly connect multiple people together to make music, remote sessions, podcasts, etc. Easily record the audio from everyone, as well as playback any audio content to the whole group.

Visual inspection is faster and cheaper than non-destructive testing (NDT) methods like radiography or magnetic particle testing.

"Quality Standard for Steel Castings for Valves, Flanges, Fittings, and Other Piping Components – Visual Method for Evaluation of Surface Irregularities,"

The primary objective of MSS SP-55 is to establish a uniform "visual" acceptance level for the surface finish of steel castings. It is designed to ensure that castings are free from harmful surface defects that could compromise the structural integrity or performance of valves and fittings. 0;381;0;407;

"A free PDF is fine for training." Fact: For legal compliance and ISO 9001 audits, your quality manager must possess a legitimate, purchased copy. Free copies will fail an audit.

Beware of free, unofficial downloads, as they may contain low-resolution images, making the visual inspection process (the very purpose of the standard) impossible. Conclusion

Note: The standard was updated to include iron and ductile iron castings in the 2025 edition. Key Features of the MSS SP-55 Standard

If your company is a member of MSS (or affiliated through VMA – Valve Manufacturers Association), you may access the PDF for free or at a reduced price via the member portal.

MSS SP-55 does not cover internal defects (which require NDT methods like radiography or ultrasonic testing), nor does it apply to weld repairs or non-steel materials.

The most notable change in the 2025 edition is the expansion of the standard's scope. Previously, MSS SP-55 applied only to steel castings. The 2025 edition now explicitly covers as well. The revised title reflects this change: "Quality Standard for Iron and Steel Castings for Valves, Flanges, Fittings, and Other Piping Components".

: Twelve types of irregularities are categorized, with five examples for each—two showing acceptable levels and three showing rejectable ones. Categories of Surface Irregularities

Often, engineers ask: "Can I use ASTM A802 instead?" Let’s clarify:

The standard is unique because it relies on a series of reference photographs rather than just text. These photos illustrate various degrees of surface irregularities, categorized into types:

BEST PRACTICES

SonoBus does not use any echo cancellation, or automatic noise reduction in order to maintain the highest audio quality. As a result, if you have a live microphone signal you will need to also use headphones to prevent echos and/or feedback.
For best results, and to achieve the lowest latencies, connect your computer with wired ethernet to your router. Although it will work with WiFi, the added network jitter and packet loss will require you to use a bigger jitter buffer to maintain a quality audio signal, which results in higher latencies.
SonoBus does NOT currently use any encryption for the data communication, so while it is very unlikely that it will be intercepted, please keep that in mind. All audio is sent directly between users peer-to-peer, the connection server is only used so that the users in a group can find each other.
For getting started and lots of more detailed information please look at the SonoBus User Guide. Or download the PDF version of it.
