Physical Part Measurement

#1
Is there a standard or specification that defines proper measuring techniques for taking physical measurements such as: Outside Diameter, Inside Diameter, Wall Thickness etc.? In my case the parts are molded and there can be variation in diameters and thickness. I am trying to determine how many measurements are necessary.

You probably need to provide more information before anyone can help you. For example:

What kind of specifications are you dealing with?

What is the purpose of your measurements? Are you doing in-process measurement? Or trying to determine if a part meets a customer spec?

Is the variation random or consistent?

No standard for those items in general...but Mike's questions are on point.
If you haven't already...peruse Miner's blog regarding gage studies...while not a "standard", they include many generally accepted proofs and methods...

The variation is random and inconsistent. The inspection is to determine if a part meets a customer specification. The parts can be .125" diameter up to 24" in diameter with tolerances from +/-.005" up to +/-.125". Thicknes or wall thickness can be a small as .035" up to .750" with tolerances as small as +/-.005" up to +/-.060".

There is always DIN 16742 Plastic moulded parts - Tolerances and acceptance conditions. Text in German and English. It is rather comprehensive.

Thank you I will look at DIN 16742. I am looking for a specification to reference or best practices for taking various physical measurements. For example how many measurement should you take on a round object to determine the OD or the ID. The objects are molded and frequently are not perfectly round. The same thing applies to wall thickness. Wall thickness on parts round and otherwise could vary depending on the area of the part and will vary from part to part. Is there a standard practice or would this be established by an MSA for each part to determine what provides a compliant part?
