What is BS EN 15416-4 - Open assembly time about ?
BS EN 15416-4 is the fourth part of an international standard used for adhesives for load-bearing timber structures. This BS EN 15416-4 helps you in ensuring the safety of you as well as the environment.
BS EN 15416-4 specifies a laboratory method of determining the open assembly time in standard climate (20 ±2) °C and (65 ±5) % relative humidity (hereafter climate [20/65]).
BS EN 15416-4 is intended to determine the open assembly time using a defined procedure for obtaining a reliable base for comparison of open assembly time between adhesives under referenced conditions.
Note: The method gives a result that cannot be applied to the safe manufacture of timber structures without taking into account the influence of factors such as timber density, moisture content, factory temperature and relative air humidity.
Who is BS EN 15416-4 - Open assembly time for ?
BS EN 15416-4 on adhesives for load bearing timber structures is useful for:
- Manufacturing furniture
- Scientific laboratories
- Building wooden houses
- Civil engineers
Why should you use BS EN 15416-4 - Open assembly time ?
BS EN 15416-4 best practice guidelines help in performing the tests for adhesives for load-bearing timber structures. This test method is useful in assessing the standard beech lap joints in tensile shear after various open assembly times. This result in an increasing coefficient of variation or helps in changing the failure mode.
With the help of BS EN 15416-4, you can conduct the test in different climatic conditions, which results in ensuring the sustainability of load bearing timber structures.
By applying BS EN 15416-4, you can determine the open assembly time and can also calculate the tensile shear strength of adhesives for load-bearing timber structures to improve quality and reliability of timber structures.
What’s changed since the last update ?
BS EN 15416-4:2017 supersedes BS EN 15416-4:2006. BS EN 15416-4:2017 includes some technical changes with respect to BS EN 15416-4:2006. These include:
- Title has been changed
- 7.2 covering failure mode has been introduced
- New definition of open assembly time has been given in 3.1
- Time intervals for open assembly times in Table 1 divided into slow and fast systems
- Requirement has been added as Clause 8
