BS 1387 is UK Standard and ANSI/ASTM are American Standards; both deals in the specifications of Steel or Alloy pipes sizes, BORE, WALL THICKNESS, chemical composition, and manufacturing process.
Both are standard in manufacturing and material process specifications.
For example;
ASTM A 53-90b Carbon-Steel Pipes, Welded (F & E Types) or SEAMLESS (S Type) Grade A & B
BS 1387 Medium (Class B) can be the equivalent etc...etc...
Composite toe shoes are made up of composite materials, such as plastic and carbon fiber. A steel toe shoe is made up of only steel.
ANSI valves are based on American National Standards Institute Standards. For example, ANSI 16.34 refer to steel valves. BS valves are based on British Standards. For example, BS1212 refer to ball valves excluding floats.
The ANSI Z41 standard, which pertains to safety footwear, does not exclusively require either steel toe or composite toe materials. Instead, it specifies performance criteria that various types of protective footwear, including those with steel, composite, or alloy toes, must meet. The choice between steel or composite is generally based on the specific needs of the work environment and personal preference, as both types can provide adequate protection when compliant with the standard.
ANSI stands for "American National Standars Institute"
PN 20 is equal to ANSI 150 & ANSI 300 equals PN 50.
Ansi 150 is a pressure grade of flange ie. Ansi #150 Flange. For steel flanges this is specified by ANSI B16.5.

The ANSI equivalent to BS 6323 CFS 38K is typically the ANSI/ASME B36.10 standard for welded and seamless wrought steel pipe. However, the exact equivalent may vary depending on the specific application and material properties required. For precise applications, it's essential to consult material specification tables or engineering guidelines that detail the mechanical properties and dimensions.
ANSI B36.10 relates to Carbon Steel Pipe, whilst ANSI B36.19 relates to Stainless steel pipe.
Composite toe shoes are made up of composite materials, such as plastic and carbon fiber. A steel toe shoe is made up of only steel.
ANSI 4135

The standards of designing steel septic tank include the NSF/ANSI Standard, and the ACI Standard.
No. It just has to meet or exceed the ANSI standards for safety toes. Many are ceramic.
