Assembly language is not a proper "programming language" per se, but rather a tool that allows you to write machine code using short, semi-human readable mnemonic instructions and link the into an executable, as an alternative to having to write streams of ones and zeroes and load them into memory. This effectively means that not only do each microprocessor family have their own assembly language format and instructions but also each processor version inside that family has its own instruction variations, but in addition to that different assemblers may use different mnemonic substitutes for each processor instruction.

Standards

Unlike most other languages the assembly language is not an artificial language that requires standardisation but rather an implementation of a practical reality that came into existence when a specific CPU was designed and manufactured, so the standard is the actual documentation of a hardware implementation. That means for 8, 16 and 32-bit processors the "standard" are the processor and programming manuals from Intel while for 64 bit assembly language you need to look towards similar manuals from AMD.
