UL 437

I have seen in UL 437 and in an Australian standard, that there are UL 437 type 1 and type 2 locks. ( https://standardscatalog.ul.com/standar ... dard_437_8 ) Key locks are either just labeled "UL 437" or "UL type 2". I didn't find anything on what type 1 or type 2 is. Does someone here know something?

PS: Combination locks are advertised as "UL Type 1", but I have read that this UL is not 437 but 2000 something. That makes sense, because 437 is for a key lock and not a combination lock.

Everything I have ever read indicates that 437 doesn't have groups and covers keyed locks. 768 is the one that has two groups and is for combination locks. There's more for lots of stuff with some overlap.

Perhaps they copied over some requirements. Other derivative standards from ANSI and BHMA don't mention grouping coming from 437.

From above link:
1 Scope
1.1 These requirements cover key locks categorized as follows and defined in Glossary, Section 3:
a) Cabinet locking cylinders,
b) Door locks,
c) Locking cylinders,
d) Security container key locks, Type 1 and Type 2, and
e) Two-key locks.

Also AS/NZS 3809-1:1998 distinguishes in table 10 "Lock requirements for strongrooms and strongroom doors" under "Lock class in accordance with UL" between "Keylock 437 (Type 2)" for lower class strongrooms and "Keylock 437 (Type 1)" for higher classes.
And dormakaba states about the La Gard 2270 "UL Type 2" instead of "UL Group 2" for a combination lock.

Type 1 and Type 2 are similar to Group 1 and Group 2. Type 1 means 20 hours resistance against picking and impressioning while Type 2 requires only 30 minutes. I know only these UL listed security container locks: LG 2270, M-Locks KL3909, S&G 6804/6805/6824 and S&G FAS 6870. From what I know about the 6870 I would would say it surely complies with a Type 2 lock. The others don't. I don't need to be three years ALOA-certified to get them open faster than in 30 minutes. The S&G Prima-MP would be a Type 1 lock, but it was never certified against anything.

Any other known UL locks?

Does someone know if there is a list of UL listed locks? There is a lot to search on the UL website, but I can't find any locks with it.
