Lab test on braided lines.

[stickbom!]

Braids are reeeeeeeally under-rated :P

[Makaira]

Now it becomes very clear why there is so much rod breakage & reel failure right??? Fireline seems to take the cake in terms of underating .... but it also has relatively higher diameter than the rest.

The ratio of the measured and specified line’s breaking strength is extraordinary; and as high as 2.593 for Berkley FireLine. I wonder which type of loading and knot the line manufacturer and independent tester adopt for their tests. Is it static or short loading which can produce different results?

On the other hand, previously the mono-line’s manufacturers were overrating, and now the braid is underrating. However, isn’t braid all about high line breaking strength to diameter ratio

errr... Richard, could you repeat that in Singlish

[mark]

let me see if i can help..

lim bei ka li kong, fireline thin thin but si bei yong, chao chao B S also got 280% above its rated strength, its really very lau sian...

long long ago, mono line mfg kong their line very tok kong but ali ba ba us 1, nowadays braided/fuse mfg lau sian us...

Hi TM,

Actually these days, the mono boys are underrating like there is no tomorrow as well e.g. Momoi Diamond. For non-IGFA rated lines, the line diameter is actually a more "less inaccurate" way of judging lines these days (what an oxymoron!!!) .... if you know what I mean. For example, Momoi Diamond 30lb breaks at almost 50#, but it is .59mm thick. That is actually more or less the same diameter of other lines that are rated 50lbs. Comparing Momoi Diamond to say Sufix Superior, its 30lb line is only .55mm thick. So, the actual breaking strength of a monofilament line; other than the quality of materials used, manufacturing process, secret formulas etc., is usually in direct relation with its thickness i.e. the thicker it is, the stronger it is, all things being equal.

It is actually a very deceptive numbers game manufacturers are playing these days. Anglers can be caught unawares & bust their tackle very easily. There was actually a chart on mono breaking strength similar to the one Mikey shared with us. I think it was published on either Sportfishing or Marlin Magazine. There was also a test done comparing abrasion resistance & knot strength of major monofilament brands. Interesting read too.

Best regards,
Makaira

Guys,

Let's use English so everyone can share the fun and information

The European Tackle Assosciation has implemented steps to standardise nylon line ratings. Now most European line makers show on their label that their line adheres to the "new standard" where the line rating is very close to the "actual test" rating. This is exactly to prevent misleading nylon lines that are way over their ratings.

Problem created because of line companies who want to claim to have " the strongest XXlb line in the industry".

Care to share which European standard, machine and test procedure are adopted?

I would guess a modified Charpy impact tester could be appropriate to measure the broad energy spectrum absorbed by the line upon a fish's strike. For example, http://www2.umist.ac.uk/material/res...arpy/notes.htm

The energy concentration during such instance is usually high up in the frequency spectrum; where most rods are marginal in dissipating the energy and hence breakage. This dissipating mechanism is mostly due to the shearing forces of the bonding resin employed between carbon fibers of a blank.

Just my 2 cents.
