What is the Future of Anti Slip Testing and Measurement?

Friday, January 5th, 2018

Pendulum Testing Device

Since the development of the first Coefficient of Friction (CoF) tests we have come a long way. The first simple, and mainly static machines, have now been supplanted by mainly dynamic testing methods with strict measures and controls to allow for some form of consistency from test to test. We now have excellent anti slip testing methods, including;

Pendulum

Covered under the BS 7976-2 method. A dynamic test. Very prescriptive controls so provide excellent reliability. Uses 4S or TRRL sliders.

Floor Friction Tester

Commonly known as the Tortus method. Tests a dry floor using a dynamic method.

Inclined planes

Typically covered by the German regulation BGR 181 (derived from ZH 1/571) these are a ‘real life’ test using a ramp that inclines using either barefoot applications or shoes. DIN51130 is the most common.  It uses an oil/water mixture to simulate an industrial slippage area, the operative wears Lupos Picasso S1 boots. The ramp is inclined to generate the CoF figure. DIN51130 test results are represented as an R figure. R9 being the least effective, R13 being the most effective. Be aware that R9 is only a plane angle inclination of 6°.

DIN51097 is to simulate a barefoot slip test. A barefoot operative stands on a plane with water. DIN51097 is required by standard GUV-I 8527. DIN51097 figures are represented as either A, B or C.  A being the least effective CoF and C being the most effective.

Static Slider

The most prevalent being the North American ASTM C1028. A static test using a weighted slider, the weight changes from 22.7 to 4.5kg. Now only typically used for archived test requirements, most requirements for this have been moved onto the aforementioned anti slip testing methods.

A Hybrid Coefficient of Friction Future?

It is unlikely that in the present future one single unified international standard will prevail. Countries have their own standard for measuring non-slip values but also the different test methods have exposed that some are more accurate than others for different situations. An approval for an international standard ISO/DIS 10545-17 so far has come to nothing but it did provide solid discussion.

Australia and New Zealand issued their standard AS/NZS 3661.1. AS/NZS 3661.1 is a ground-breaking standard for anti slip requirements, it brings in multiple testing methods, each one already proven. The test includes;

  1. Floor Friction Tester for dry tests.
  2. Pendulum with 4S and TRRL for wet tests.
  3. Inclined plane tests DIN51130 and DIN51097.

The standard later moved to AS/NZS 4586, handbook HB 197 and eventually AS/NZS 4663.

In 2003 work was performed on a European standard, SUA 1 brought in ENV 12633. Work is still ongoing but it encouraging to think that this may, eventually, evolve into something that can work across all borders and cover all materials.

ISO7010 Colour Standards in Factory and Warehouse Marking

Thursday, December 21st, 2017

warehouse optimisation with permarouteInternational standards are becoming more prevalent for our warehouse marking tape PermaStripe. One of our aims is to always inform our customers of what standards are potentially applicable and to provide some form of detail.

What is ISO7010?

ISO7010 is the international standard created in 2003 to assist with consistent safety sign regulation across Europe. This regulation concerns workplace safety signs and colour markings for accident prevention, fire protection, health & hazard information and emergency evacuation. Regulations are put in place to help provide a standardised system that is recognised throughout Europe.

permaroute colour standardsInterestingly, the UK didn’t adopt this standard until 2013, before then abiding by its own standard, BS 5499. The UK changed to ISO7010 in January that year once the standard became a European Normative ( EN ) and adopted by European law.

Heskins try to choose colours that are vibrant and are a true representation of the colour being neither too dark not too light. We now produce a range of colours that match ISO7010, the colours apply to both rolls and warehouse markers. The colours used are detailed below;

  • Black – RAL 9004 Signal Black (used on all as representation for black)
  • Blue – RAL 5005 Signal Blue (used for warehouse markers)
  • Green – RAL 6032 Signal Green (used for PermaStripe, green/white PermaRoute and warehouse markers)
  • Red – RAL 3001 Signal Red (used for PermaStripe, red/white PermaRoute and warehouse markers)
  • White – RAL 9003 Signal White (used for green/white PermaRoute, red/white PermaRoute and warehouse markers)
  • Yellow – RAL 1003 Signal Yellow (used for PermaStripe, black/yellow PermaRoute and warehouse markers)

Anti Slip Tape Roll Lengths

Monday, November 27th, 2017

anti slip tape lengthsOur conventional anti-slip tape roll length is 18.3m, a strange metric length. 18.3m goes back to when ‘Imperial’ lengths were more normal and is the equivalent of 60 foot. The foot measurement is still prevalent at our US sister company Heskins LLC. For us in Europe when communicating with our American colleagues we have to rapidly mentally switch from mm, cm and metre to inches, feet and yards in an instant!

Although 18.3m is our most common sales length we also produce many other options, almost any length. Short lengths rolls such as 3m, 5m and 10m are typically for retail sales. These lengths are ideal for putting onto shelves and are an attractive sales proposition. The shorter length means that the product is lighter so does not create hanging issues. Long lengths such as 50m and 100m are normally used for production requirements but there is also a requirement to have an exact specified length to accommodate requirements. All lengths are possible, please ask as we are happy to discuss what is perfect for your company.

Measurement Trivia

On a side note talking about the foot length, just a bit of trivia!  I looked up how it was determined what an exact ‘foot’ length was, how could they be certain in old times, well, I found the answer!  Jacob Koebel in the 16th century determined that on a Sunday at church the first 16 men who left the church were to stand in a row with their left feet touching end to end. The total length is divided by 16 and that is the correct distance for a foot so now you know that 60 of them average foot lengths make up one of our rolls!
